Royal Enfield Meteor 350 - Larger Front Sprocket

- In this video, we fit a larger front sprocket to the Meteor 350, for more top-end. We've already fitted a DNA air filter. This combination should give us good performance and a higher top speed. Let's find out...
without remapping the console there is nothing to do, the Brazilians have already done it and the final speed goes up to 83mph
Yes. Definitely worth looking at what they’ve done in Brazil.
Look at the wiring diagram. There is a way to fool the ecu... Ive done it
Never ever going to get higher top speed just with gearing alterations. The bikes are not rev limited !!! They are speed limited with the readings being taken from the ABS sensors. And even the removal of the sensors simply puts the engine into limp mode . Until someone starts selling replacement ECU units with the speed control function removed there is no way to get this engine to do what we all know it should.
We hear so many conflicting and strong opinions on rev limited vs. ABS sensor vs. both. Whether the top-speed is higher, lower, or the same, it was never going to become a fast bike. With the sproket, DNA Air Filter, and exhuast, I'm much happy with the overal performance.
Oh yes those mods have made a big difference to my Meteor Too. I have just purchased an uprated camshaft from Hitchcocks I'll let you know what I think in due course. I don't particularly Want a speed machine but would like it if I could sustain long milages at a lower R.P.M. Apparently the new cam enables a smaller rear sprocket to be fitted ,although I guess that would reduce acceleration in lower gears, but with torque coming in lower down the rev range. I'll have to experiment and see what is most comfortable for touring and everyday use.@@MotorcycleFettlers
Thanks, Graham. Yes, please do let us know how you get on with the camshaft.
nice vid or would have been if the camera man had filmed all the adjustments, which he did not, (you were using a chisel on the sprocket tab????, your hand totally covered the action!, he did not move the camera to catch the visuals, amateur, he did not get the finished look of the tab at all, just left it hammering away, no idea what it should look like after the work with the chisel was done.
This seems to be an important fettle but the bad camera work totally ruined it, pity.
Wow. Blame the cameraman / editor / comment responder. I am an amateur! You think someone pays me for this? If you could see what I have to work with everytime I piece together one of these videos... When you look at the sproket, initially, you'll see how the tab sits. He used a large screwdriver to start it off and then knocked it down with a blunt instrument (a bit like rhe camerman) so that the tab sits on the flat of the nut. A blunt chisel will do this if you're careful.
I bought one of the first triumpph 790 scrambler. It was really over geared so i bought a rear sprocket 5 teeth larger and then it was perfect. If i could do that why couldn't triumph ?
Thanks for the comment. I don’t understand why Royal Enfield haven’t given their bike a little more performance for foreign markets like the UK.
I Totally agree with that as I know for a fact that during the first stage testing of the platform that it was running round capable of 90mph top speeds. so they know how to set an ecu up for that speed . which would give us an awesome touring capability being able to hold motorway speeds, with enough in reserve for any overtaking we would have to do.@@MotorcycleFettlers
Some time ago, I put a one tooth larger front sprocket on a Honda Rebel 250 with the intent of making the engine run at lower revs at 55-60 MPH. I was happy with the result. I didn't notice any gain in top end, but that's not what I was after. Since you seem to have noticed a similar effect with the Meteor, I'm seriously considering a switch for my bike. Thanks for the video!
It did need the DNA filter and silencer, but I like the difference. Thanks for watching.
You might have seen my videos on the removal of the speed limiter and other mods. Can you explain why the sprocket change is a good idea and what it does, and is it worthwhile?
With the air filter and exhaust change it made the gears shorter. A tooth larger really makes a lot of difference. I hadn't seen your video, but I have now. Very interesting. Thanks for sharing.
@@MotorcycleFettlers in what way does it make a difference? I’ve looked at lots of reviews and pretty much everyone has said they’re changing back. It makes the acceleration slower but once up to speed, the revs are around 500 slower at the same speed, however you are having to downshift when needing more acceleration so the increase in mpg is negated.
With the air filter fitted it makes first gear really short, as in you have to change into second really quickly, and I prefer the way it goes. It's more relaxed. It was not very good higher up the rev range in higher gears until we changed the exhaust for less restrictive one. Now it revs to the limiter, in top. Before, it really struggled in top until the exhaust was changed. One would imagine that 85 mph would be possible if I was to change the throttle body, as you did.
Good vid
At least you were careful cracking the sprocket nut .
Saw one guys post with a chrome classic saying put it in gear and a bar throught the spokes onto the swinging arm
It made me wince to say the least.
How to knacker your wheels pronto.
Will I change mine?
Don't know.
DNA filter? yes.
Cat replacement pipe? yes
Then I'll decide as for me they make the biggest difference
But thanks for the over view of this little job .
Saves others running into hiccups as you would have found them first😊.
Cheers mate

Thanks for your feedback, Lee.
I saw that same video definitely not the way I’d like to try.
sadly, a bigger sprocket won't allow you to exceed a certain speed coz there's a built in electronic limiter in the engine. personally, i'm ok with 70 mph.
I believe it's rev-limited, so it does make a difference; especially with the DNA air filter. I'm more than ok with 70mph on something like this, but it's nice to have a little extra when you need it. It's surprising how many very low-mileage Metors are for sale, which a dealer told me is because a lot of people think that these just don't quite have enough go.
It has an engine RPM limit plus a speed limit set by the ABS ring pulse signal. Until someone brings out the bypass for that no amount of sprocket fiddling is going to give it more top end speed. I imagine RE know how to switch the limiter off but are holding back for later generations of this bike.
There's seems to be some discussions on whether or not it has a rev limiter, a speed limiter, or both, and how this may vary between countries. Hitchock's Motorcycles have said that it is not a speed limiter, when we asked. What I can say for sure is that, with the smaller front sprocket, it does record a higher top speed on the speedo.
@@MotorcycleFettlers If you watch the video Hitchcocks put out they do say there is both a rev limiter and a speed limiter and they are separate. I'm intrigued by you claiming that it has made a difference to top speed as the 3 I've done this to have not made any difference to top end, but have reduced the revs to a very comfortable pace at cruise.
Thanks for the comment. I shall have a look for the Hitchcock's video. That would be at odds with what I was told. The top speed difference that I have observed is not huge. I can only go by what I've observed whilst riding, and this may be subjective and condition dependent, but my overall impression is that these changes have made a useful and meaningful difference.
So higher top end at the cost of lower acceleration and throttle response, also any improvement on the air filter side will be negated by the sprocket switch, seems counterintuitive for 3-4 mph
Thanks for the feedback.
Wow, it's Bamber Gascoigne's vest.
anything about speedometer error ?
Shouldn't effect it as it's to do with wheel sizes.
To be honest I think the bike lacks power to pull 5th anyhow so my idea would be a smaller front sprocket to improve acceleration. Looked around and doesn't seem to be much available though unfortunately
Thanks for your feedback.
Excellent...not on the King's highways 🙄😆
No, most certainly not!
Thanks for sharing. Hoping to find someone to make real forward controls for the Meteor.
I hope so too
Any change did you notice on the mileage of the vehicle after sprocket change.. question from INDIA
We made a number of changes. Overall, the MPG is around 90 and we gained a couple of extra MPH, maybe. Overall, I prefer the profile of how it rides and the MPG is still good.
Good explanation. I hope to do this when the weather warms up again
Thanks for the comment. I’m sure it will warm up soon…
any changes in fuel average ( miles per litter) after installing 16 teeth sprocket
With just a sprocket change one would expect an increase in mpg but as I've changed the air filter and tail pipe it's actually less mpg but still getting around 90+ so I'm quite happy
Does this mean we will be getting lower RPM at the same speed as previous ?
Yes it does, but without the other mods that we've done, it will not pull 70.
Are you still running the meteor with the same mods and do you still have the cat fitted
I've not made any further changes. I sometimes think about changing the camshaft...
Opa qual a numeração do retentor do câmbio da meteor estelar 350 21/22
Desculpe, não tenho certeza do que você quer dizer.
I find 4th gear top speed, 5th gear is more overdrive. In this respect adding taller gearing is not going to get you around the power limit.
Thanks for the feedback. We'll get hold of standard Meteor soon and have a shootout. Subscribe and watch this space...
What top end speed in m/h give this 16 tooth Sprocket more then the 15 tooth Sprocket?
Hi. I get an extra 5mph over standard. That's with all the mods...filter, spocket, and silencer. I think you need the other mods, if changing the sprocket. I do have a ride out video if you want to see how it performs.
Nice video thanks! I have seen after market 16T sprockets for sale but they don't have the rubber side spacer mountings on them. Are they necessary?
Now you're asking.... The one I bought had rubber both sides. I don't know what the difference is but I went for one from Hitchcocks.
Hitchcock are out of stock
ah...
👌👌👌👌👌👌👌
Thanks for your feedback.
Hello, have you done a test drive after you did the modification to the Meteor? Best regards
Yes, We've done the first test rideout. Excellent performance from this upgrade, when combined with the DNA air filter. She now tops out at 77MPH.
Before the new sprocket it was really buzzy but now with this fitted, it feels just right.
I can overtake easier as the the power seems to be in the right place.
@@MotorcycleFettlers hello 77mph is speedo indicated or gps?
@@MotorcycleFettlers woow pls do a real test POV. Thank you!!!
@@ellwindaniel9441 On the speedo, so it will be a little slower that 77 but an improvement from the standard set-up.
@@Nordiclord We shall do a proper rideout
Have you done research on how to get more linear torque, as meteor has smaller wheel the gear ratios are lower resulting faster acceleration compare to classic 350 which has same engine but bigger wheel, meteor setup is not a true characterstics. Of cruiser. I want the tune or setup jus like classic 350 on meteor - any ideas thoughts please
I found that the mods I have made have increased the cruiser feel. When the DNA filter was fitted the bike seemed a lot more revvy and 1st and 2nd gears were very short, as in that you had to change very quickly, so I changed the sprocket and this gave a much more relax feel to the bike but I lost what little power I had at the top end. It wouldn't pull the top speed unless I was going down a slight slope. When I changed the tail pipe for a less restrictive one, the bike became lively again and will now pull a lot better and will pull on an upwards slope. The top speed has increased but not by much. It's only an extra 5 mph but it will cruise down a motorway at 65/70.
@@MotorcycleFettlers thanks a lot for quick reply - so you mean these sprocket are designed for linear torque ? And feels like classic 350? Which exhaust you have ?
The air filter u changed to stock ?
The silencer is an original RE silencer, just more straight-through than the standard. We changedthe standard air filter to a DNA air filter. I hope this helps.
what was your new top speed? would you recommend someone else doing it?
Top speed was 77mph (on the clock). Defintely worth doing if you want a little more from your Meteor and it's great fun doing it. The air filter is simple to change. You need to be a little more mechanically-minded if you want to change the sprocket and you needs some tools, including a torque wrench. For the sprocket, a second pair of hands is helpful.
What torque did you use to tighten the sprocket nut?
Torque 130-160 N-m/13.0-16.0 kgf-m
@@MotorcycleFettlers Thanks 👍🏼
Very interesting 😊
Glad you think so!
I could follow it but a novice wouldn't. More pictures are needed of individual parts and a better video. Much of what you were doing was obscured by your hands
Thanks for the feedback. We do our best.
I have changed the front sprocket on my Meteor as well as the air filter and it is indeed faster top end it is a rev limiter according to Hitchocks and no other limiter.
Thanks for the comment. It makes a real difference.
Unfortunately a larger sprocket is a waste of time and money. The engine doesn’t produce enough torque to adequately pull the taller gearing. All that will be achieved is to load up the big end bearing.
Thanks for the comment. We've changed this as part of a number of modifications including a DNA air filter and less-restrictive silencer. The proof is in doing it and we've done it and it makes a meaningful difference.
