The reason why you feel the heat more on the VFR compared to the 600RR isn't because of the exhaust routing - it's the engine type. The CBR is an inline 4, so the engine heat is forward of you. The VFR is a V-4, so you have the rear bank of cylinders right there under the tank and between your thighs. It's the same reason Ducati's are constantly called uncomfortable because of the heat, be it the twin or V-4, that rear bank will keep the rider "warm" and limber.
Exactly. I love it so much. My bike journey so far (british so I gotta deal with shit laws). Pulse 125 (chinese sumo) Honda CLR 125 (retro scrambler) Yamaha MT03 660 (street moto) Aprilia Dorsoduro 750 (XL Moto)
You should have addressed the original reason for undertails in the first place. They first showed up on 2 stroke race bike where the engine needed long and complex exhausts for maximum power. Then it just became a game of street bikes looking like their racing cousins. Now we don’t race with 2 strokes so short pipes are back in. If anyone ever figures out clean 2 strokes long pipes will be back.
I definitely don't notice the heat on my CBR600RR either. But the engine throws enough heat that more than makes up for that Haha. Undertail exhaust was one of the main factors in my decision making when buying the bike though. I love the look.
Yeah the look is gorgeous, I'm surprised more mid tier bikes don't do it as they can't really be raced. Just make a super sweet looking bike that makes up for it's extra weight by making the engine 36 CC's (or whatever) bigger.
@@GeneralAsimov agreed. I much prefer the aesthetics of the undertail look. Nice and tidy. And for those of us that have no plans on tracking our bikes, its no big deal. My 600RR has more than enough power.
Moto moose cbr 600 sounds really nice but I got the fz6 s2 because it has less higher pillion seat, so that people won't have trouble getting up (my mom especially )
@@jacksonjr.1400 that makes sense. I'm pretty short so sometimes I have a hard time with the 600RR. But I love the look of sportbikes too much to change to something else.
The under tail exhaust one of the sportiest looking features ever put on a street bike. Any issues with heat under the seat can be eliminated with some cheap heat shield or a few exhaust lowering links. On the other hand a good aftermarket slip on is pricey and when I fork out the cash for one it would be nice to see it.
Timothy Buchanan Ever own one ? After 10 years of having a undertail exhaust on my R1 , sold the bike and dont miss that part about it one bit. Love my FZ09's exhaust, I dont feel heat it at all even with full Graves titanium exhaust.
Timothy Buchanan Nice bikes, my buddy has one, but being a 600 and single exhaust can I think they are not even close to as bad as my R1 was. Although a full exhaust with cat removed instead of just slip ons on R1 might have helped.
Lassi Kinnunen. If the exhaust was done something like what you said it would probably look pretty good. Something like on the ninja h2. I think the point of the under tail is the looks not performance. Its longer heavier and more expensive. The under tail is all about looks. With all of its disadvantages performance wise it still has one great advantage most forget about. When you low side or drop your bike like almost everyone does at some point. Your $700+ muffler doesn't get destroyed. Personally I like the way the 2015 ninja h2 exhaust design the best but it only looks better if you run a full titanium. $5000+. So in short can't beat the looks of the under tail.
Buell Pioneered the underslung exhausts almost 20 years ago. I watched a video explained why he did that. He had a muffler, hugged it against his body & turned around. He then held it out arms stretched & it was harder & slower to do it. It’s amazing it’s taken 20 years for the rest of the industry to catch on.
Well. Honda redesigned the 600RR for 2024 (for sale basically everywhere but America) and kept the undertail exhaust. Don't worry. I'm just as surprised as you are.
It's one big thing that makes me love the look of my '09 Street Triple so much more than the newer models. It's a real shame that they're becoming so much less common.
One important thing missed - Heat from the undertail exhaust pipe passes next to the rear shock, slightly changing it's dynamics as the shock heats up. Ultimately the technology didn't exist to pack 9000 cats underneath the bike until recently, but it's safe to assume the advantages drove the innovation.
I agree, I've had 848 Evo and 1098 with termis, almost same bike as you and super hot. But I disagree with winter, it doesn't really heat you up but I lean back and stick my hands under the tail at every light and my God can that ever help.
Where i live we got snow in the winter and basically icy roads everyday. But in the start spring and atum heated grips is freaking AWESOME! Highly recommend, but don't cheap out and buy some off brand chinese ones, buy from a decent brand and you'll love em :)
@@maartos There are two types of bikers: There are guys who have a bike because it reminds them of a time where their life wasn't so fucking boring and they hadn't given up yet. Then there are real bikers, who live and breath bikes. Yes we ride whenever we can
What a pleasant thing to watch a video that goes straight to the point and doesn't spend 12 minutes on bullshiting about subscribing or the youtubers own life. Thanks for that.
The only way I can see an F4 is with the undertail exhaust. But if they do redesign it would be nice to see a design like what is on their F3 with the pipes coming off the side
So, whatever your video was about, that 916 at 3:16 looks slick. 99.99% of us aren't motogp riders, 95% of us aren't trying to win the local road GP. But when you walk into your garage, and see that beautiful beast, that is better than any 1/10 of a second anywhere.
they will never be discontinued, they move heat away from the engine faster allow consistent back pressure , allow better air dynamics and don't get destroyed in a low side slide. In fact more and more manufactures are redesigning ways to use them instead of the side exhaust.
I love under tail exhausts as well. On my 05 cbr600rr I removed the heat shield and never felt any heat from it. The bike did push heat to my legs from engine temps though. I had a titanium akrapovic exhaust system with carbon fiber canister at the end.
yup and doesn't effect balance at all and heat is not an issue for rider or suspension, but we are talking about Honda, the best engineered motorcycles in the world Bar None....I didn't say fastest...I Said best engineered.
tinwoods I guess Lorenzo and Dovi are squids since their Ducatis have the same exhaust set up -_- But then again, I prefer the under engine exhausts on the Panigales.

It makes sense. One benefits from experience with the qualities of both to appreciate how it affects the handling. On my first outing in the Bershire Intl. trials on an OSSA enduro back in '70, I attached a really spiffy looking round metal tool container from an old Honda 160 just aft of the seat on the fiberglass tail. I hadn't noticed it affecting the handling until I actually was underway on the first day - and it wasn't good. It affected the feel of the machine much greater than I would have suspected and the next year did away with it to carry tools somewhere else, including in my pockets. The difference was remarkable.
On my fz6, i rode it back home from buying it on a hot day and kinda really disliked the heat from it, now it's cold here and I don't feel any of the heat either. Hit home for me haha
Weird vid. Almost the first statement "Moto GP bikes use undertail" contradicts the whole premise of the sweeping statement that undertail pipes are going away. How about sports bikes that are built in the full knowledge that will spend their life on the track and the stock can will be in the bin within 15 minutes of the bike coming out of the dealership (ahem... GSXR 1000). No underseat space needed, and with a carbon fibre pipe it will be light as anything. The "gasses travelling further" premise I also question, although I don't know the physics of it, but I know what my old GSXR 750 was like with a full length RS3 and cut down RS3 - the shorty robbed 6bhp off the top. I think "forever" is a strong word...
Some Motogp bikes have dual exhausts that have an undertail and a side mount. I believe the reason for this is on v twin bikes having one of the exhaust go out the tail is easier and more compact then going out the side. Although that’s just a theory. I’m not sure why they do it.
HeroRR I am not sure they run v2 in any series anymore... Furthermore I believe (without checking) that Honda runs one of these setups which blows your theory out of the water
This is your opinion. Motorcross and trail bikes have had the exaust under the seat for,,,,,,EVER! They will never move them and as for road and race bikes it is just evolution some will some won't. The first road bike that had the mufflers under the seat is the Honda NR750, the bike the Ducati 916 was heavily copied from and of course the MV F4. I doubt they will change that any time soon. As far as making a handling problem at least 14 bikes with the pipes under the seat have won the World Superbike Championship, Including Ducati and Honda! Also trunks are for Elephants!
Couldn't live without under seat storage on my 929. Was gonna sell for something more comfy like an MT or Triple. Ended up doing a Renthal bar conversion and keeping it. So useful.
My Ducati has plenty of trunk space (more than my other bikes), and having the exhaust mounted in the rear keeps the engine area cooler which helps ALLOT
Fun fact, you feel the exhaust heat not only because heat rises, but on a hot day the air is already hot and doesnt rob the exhaust of its heat (obviously) on a cold day, the thick dense cold air only disipates the heat, but pushes it down
My Triumph Street Triple has the pipes under the seat as well. Yes the heat can get serious on a hot day. But I really like the way they look on the bike! 😎
A carbon muffler was probably the best mod I ever did to my 600RR. You could pull off the track after a 20 minute session and grab the muffler with your bare hand and not get burned.
I've got a 2 bros system on my 02 VFR800 and I don't notice the exhaust heat on my rear so much as I do from the pipe going up to the can. That bad boy roasts the calf on a 100 F + day.
I was expecting the older R1 when you were mentioning bikes with under tail exhaust. Cool video though. You always have interesting content in your videos!! :) Cheers
2:26 yeah your bike cools down real fast on cold days. i use to ride my bike during the winter and i had to stopp every 5min to warm upp my hands on the exhaust. if i touched the exhaust right away it whould burn my gloves but if i waited like 40sec then that was enough to cool down the exaust to where i could hold my hands on it without melting the gloves. and the bike was on the entire time so yeah that heat disapears real quick in the cold
The only time I've ever noticed feeling a noteworthy amount of heat from my CBRs undertail exhaust was when the bike was overheating up to 124 degrees.
Racing bikes began using under-seat exhausts in the 1970s for a number of reasons: to cut drag, improve balance, place the outlet in the bike’s vortex for more efficient gas exit, increase lean angles and make the exhaust long without curling the pipes. Also, there are more electronics now, like traction control and ABS, those computers need to go somewhere and they usually end up under the seat. Why they went away....strict emissions.... bigger cans can't fit under the seat anymore so they have to push them under the engine.
When I bought my F4i, the seller was like, I have an under tail kit for this if you want to buy it? I was like, uh, no. Thanks. It already had an exhaust. I’m not buying a new exhaust for a 15 year old bike that already has one. Not to mention all the work.
Lets not forget catalyst placement/heat issues. All bikes these days have cats and they need to be close to the engine to light off quickly and stay hot under all conditions. For simplicity and weight savings (not to mention mass centralization) its just smart to incorporate the collector, cat, muffler and O2 sensor into a tidy package and stuff it all under the engine, at the lowest point on the bike.
I've never ever felt the heat from my undertail, and I run a aftermarket exhaust the weight is a fraction of OEM. I will agree that the exhaust does travel further creating slightly more back pressure, but it's non noticeable to the every day sport enthusiast. In a gasoline engine the less back pressure the easier the engine can put out the HP it's designed for. With two strokes it's the opposite. In all reality it's only for aesthetics from the days of the 80's when racing bikes were mainly two strokes and needed the extra back pressure. Companies that still manufacture undertail exhaust systems are behind the times and are not being user friendly to the rider that likes to work on his or her own bike
But why are exhaust on both ends of the bike like the old kawasaki z1, ex250 (classic ninja 250) and honda nighthawk 750 gone? Like my old 07 ninja 250 makes more power at top than the newer 2008-2012 ninja 250 but the old ninja 250 makes less torque.. so does one exhaust increase torque?
I have the VFR800 VTEC and the standard rear part of the exhaust weighs (cat up) 8.7 KG and is noticeable as that weight is high up and to the very rear of the bike. Made my own and now is half that weight and makes a very noticeable difference. I would of made a low down system if it was not for the big void left under the tail. Would of then been able to get it down to a 1/4 of the weight beside having that low down. As to heat, not an issue in the UK as it rain most of the time.
The under tail exhaust was one of the top reasons I fell deeply in love with my R1.

GSXR 1000). No underseat space needed, and with a carbon fibre pipe it will be light as anything. The "gasses travelling further" premise I also question, although I don't know the physics of it, but I know what my old GSXR 750 was like with a full length RS3 and cut down RS3 - the shorty robbed 6bhp off the top. I think "forever" is a strong word...
Some Motogp bikes have dual exhausts that have an undertail and a side mount. I believe the reason for this is on v twin bikes having one of the exhaust go out the tail is easier and more compact then going out the side. Although that’s just a theory. I’m not sure why they do it.
HeroRR I am not sure they run v2 in any series anymore... Furthermore I believe (without checking) that Honda runs one of these setups which blows your theory out of the water
Max Mazourov GP bikes lean to much and benefit. They do not need the storage space and one only sits on them for a short time.
They run V4s, with 2 cylinders per exhaust for better pulsaltion dynamics.
Really enjoyed your video. All the best,

This is your opinion. Motorcross and trail bikes have had the exaust under the seat for,,,,,,EVER! They will never move them and as for road and race bikes it is just evolution some will some won't. The first road bike that had the mufflers under the seat is the Honda NR750, the bike the Ducati 916 was heavily copied from and of course the MV F4. I doubt they will change that any time soon. As far as making a handling problem at least 14 bikes with the pipes under the seat have won the World Superbike Championship, Including Ducati and Honda! Also trunks are for Elephants!
No likes for your ignant comment
A lot easier to cross a ford in some extreme adventure bike without the exhaust underwater, can be done but easy to kill the engine with backpressure.
Man I super appriciate all your videos and all the work you put in to make them. Thank you much bro!
Undertail exhaust ruins the lines of a sharp tail..
Neito Kradavish no
Take a quick look at the Desmosedici RR, then rethink your statement.
I love the undertail on my 600😔
I DON'T CARE!!!
PEOPLE BUY BIKES BECAUSE OF LOOKS AND SOUND!! THIS IS PATHETIC!!
This didnt aged well ....... :D
You forgot the terrible smell it leaves on your clothes, especially if you have an aftermarket exhaust.
Not if it is tuned right.
Couldn't live without under seat storage on my 929. Was gonna sell for something more comfy like an MT or Triple. Ended up doing a Renthal bar conversion and keeping it. So useful.
My Ducati has plenty of trunk space (more than my other bikes), and having the exhaust mounted in the rear keeps the engine area cooler which helps ALLOT
Erik Buell slung the whole thing under the engine on the old XB and that is a sweet handling machine.
Fun fact, you feel the exhaust heat not only because heat rises, but on a hot day the air is already hot and doesnt rob the exhaust of its heat (obviously) on a cold day, the thick dense cold air only disipates the heat, but pushes it down
Still gonna chuck one on my future “big” bike
My Triumph Street Triple has the pipes under the seat as well. Yes the heat can get serious on a hot day. But I really like the way they look on the bike! 😎
A carbon muffler was probably the best mod I ever did to my 600RR. You could pull off the track after a 20 minute session and grab the muffler with your bare hand and not get burned.
Didn't go away, Honda CBR 600RR still has em. Why do you think they didn't go away?
It's going away now, with the E-bike
I don't have a fast motorbike but I love this look on a classic, so I'm doing it.
Whatever it takes!
Happy to report that the new 600rr has got one.
2 years later and Honda is still rocking it
straight to the point, no mumbo jumbo 👍
I've got a 2 bros system on my 02 VFR800 and I don't notice the exhaust heat on my rear so much as I do from the pipe going up to the can. That bad boy roasts the calf on a 100 F + day.
My 2010 Buell Lightning has the exhaust all the way under the whole bike! Love it!
Undertail exhaust on the Ducati always caught my eye. Ive got to have one!
I was expecting the older R1 when you were mentioning bikes with under tail exhaust. Cool video though. You always have interesting content in your videos!! :) Cheers
You have any issues with your jacket/backpack smelling like exhaust fumes with yours after riding? Mines really bad on my 05 1kRR
whats your opinion on the under belly exhaust like in the KTMs?
2:26 yeah your bike cools down real fast on cold days. i use to ride my bike during the winter and i had to stopp every 5min to warm upp my hands on the exhaust. if i touched the exhaust right away it whould burn my gloves but if i waited like 40sec then that was enough to cool down the exaust to where i could hold my hands on it without melting the gloves. and the bike was on the entire time so yeah that heat disapears real quick in the cold
The only time I've ever noticed feeling a noteworthy amount of heat from my CBRs undertail exhaust was when the bike was overheating up to 124 degrees.
Racing bikes began using under-seat exhausts in the 1970s for a number of reasons: to cut drag, improve balance, place the outlet in the bike’s vortex for more efficient gas exit, increase lean angles and make the exhaust long without curling the pipes. Also, there are more electronics now, like traction control and ABS, those computers need to go somewhere and they usually end up under the seat.
Why they went away....strict emissions.... bigger cans can't fit under the seat anymore so they have to push them under the engine.
Another great video bro!
2 brother exhaust curse i have :C what should i do burn down the whole bike or bring to scrap yard?
Curious: would it be a problem to have the exhaust exit at the bottom, ahead of the rear tire, firing downwards?
Is there any already available to buy for a 2008-2010 Yamaha R6 or would I need to get one custom made?
Under tail exhausts are more aero dynamic so faster top end especially above 120.
What are your priorities
When I bought my F4i, the seller was like, I have an under tail kit for this if you want to buy it? I was like, uh, no. Thanks.
It already had an exhaust. I’m not buying a new exhaust for a 15 year old bike that already has one. Not to mention all the work.
Might wanna check out the new CBR600RR ;)
Lets not forget catalyst placement/heat issues.
All bikes these days have cats and they need to be close to the engine to light off quickly and stay hot under all conditions.
For simplicity and weight savings (not to mention mass centralization) its just smart to incorporate the collector, cat, muffler and O2 sensor into a tidy package and stuff it all under the engine, at the lowest point on the bike.
Also does under tail exhaust further complicate license plate placement
What's old is new, will definitely be back
Under tail exhaust is the best! My 04 CBR 600RR looks amazing with it
I've never ever felt the heat from my undertail, and I run a aftermarket exhaust the weight is a fraction of OEM. I will agree that the exhaust does travel further creating slightly more back pressure, but it's non noticeable to the every day sport enthusiast. In a gasoline engine the less back pressure the easier the engine can put out the HP it's designed for. With two strokes it's the opposite. In all reality it's only for aesthetics from the days of the 80's when racing bikes were mainly two strokes and needed the extra back pressure. Companies that still manufacture undertail exhaust systems are behind the times and are not being user friendly to the rider that likes to work on his or her own bike
But why are exhaust on both ends of the bike like the old kawasaki z1, ex250 (classic ninja 250) and honda nighthawk 750 gone? Like my old 07 ninja 250 makes more power at top than the newer 2008-2012 ninja 250 but the old ninja 250 makes less torque.. so does one exhaust increase torque?
I have the VFR800 VTEC and the standard rear part of the exhaust weighs (cat up) 8.7 KG and is noticeable as that weight is high up and to the very rear of the bike. Made my own and now is half that weight and makes a very noticeable difference. I would of made a low down system if it was not for the big void left under the tail. Would of then been able to get it down to a 1/4 of the weight beside having that low down. As to heat, not an issue in the UK as it rain most of the time.
