Motocross Action takes a deep dive into Jared Lesher's Yamaha YZ250 Two-Stroke. Yep, that's right, a two-stroke competing against the fastest 450s on the planet. But Jared and his mechanic Michael Shaw have a couple of tricks up their sleeves in order to stay competitive with the Premier class. Covered in titanium and carbon, very little of the bike still resembles it's stock counterpart as Jared's race steed is covered head-to-toe with upgrades. So take a closer look at this fine motorcycle and even get a sound sample for yourself.

AMA HAS to make a two-stroke class. Would be SO SICK.
They have to ride both.
Or just allow the displacement to be fair 👌🏼
Yep. Feld fails to realize how social media has allowed the Privateer and mid pack guys to be underdog hero's. I screamed for Lesher. Screamed for Moranz. It's so fun rooting for the Underdogs on their journeys and adventures in the sport. It's no longer a 1 champ sport. Add a 2 stroke class and the fans will be jumping out of their seats for a whole new crop of winners and contenders, bringing greater marketing value to the sport.
There will be an EV class before they bring the two stroke back.
@@motofunk1 Fans would prefer 2 stroke.
Thanks guys for the opportunity to showcase our bike on here!
Congratulations on making history this weekend!!!
That bike is so rad. I always wanted to do a throwback build like this, powdercoated frame included.
Congrats on making the Atlanta main
@@jrod4717 Thank you
His bike is truly a work of art. Love seeing and hearing the smoker out there. If you were to guess how much total money is wrapped up in this bike build?
@@alexpanneton2215 Hard to say with sponsors helping out a bunch, and a lot of R&D work done on the motors to get it right. Also we lease our suspension from Enzo, so that helps
Much respect guy keeping the 2-stoke alive in supercross. Just got back from ATL race great to see you in the main event.
Detroit Supercross was prob best I've seen all yr. Ford Field is epitome of stadium racing quite possibly . Kudos to Ford family!
Beautiful yz250! love the full fmf and gold rims with the retro style graphics and white plastics
Indeed! My thoughts too! Beautiful bike.
I fn love it. In Australia we got the European YZ's which were white and red. Beautiful. I think they were and are the best looking bikes and colour scheme in the world. A crisp clean colour scheme always
@@gb4408👍🇦🇺
Same except those fugly green marks on top of the front plate ..
@@jinoziniosti5633 I think your referring to the cdi box which is green. There are some green highlights for the Monster Energy drink on top of the number plate
So happy he put it in the MAIN at Atlanta!! 🤘🏼🤘🏼🤘🏼
Just love two strokes!! Hope they are coming back more and more👍👍 Nice bike!
Na, never will come back into pro racing.. I have a few 2T love them, but 4T is a better racing machine !
Always listen out for this guy. Miss the days when it was all 2 strokes with the lone 4 stroke
Hell yeah!! Met these guys in Arlington, super cool dudes, super sweet bike. Best sounding/looking/even smelling bike in the pits for sure
As an owner of an 87 YZ back in the day, really like the color scheme.
87 😳
Yeah it's awesome! I had an 87 yz80
The mentioned STIC Keihin carb meter block insert is no joke. While providing big gains to the low to mid, it also adds peak hp and over-rev. 30 minute max install time. BTW, both jets go up 2(pilot) and 5(main) steps. So he's not kidding when he says it helps a lot. It creates a rapid cooled vapor delivery. When a head requires 98 octane on a 125 for example, premium pump gas can be used. My old KTM 200SX engine is bone stock and I went from a 100/90 to a 110/80. No drop in lugging or power delivery. That's equal to 2.75 teeth down on the rear sprocket! It's like going 25cc big-bore, but it revs much quicker and farther.
I love when people ask our jetting and they think i'm crazy. It really is impressive what that thing does, and it sounds wicked compared to a stock carb.
@@Shaw413 But how much gains power wise? The website is a bit fishy, claiming it would give you 2-3-4 + HP. That would be more than a pipe and silencer combo. Basically are there some true estimates numbers? Derek should updates his S.T.I.C insert video put it to the test on a stock 250 two stroke, - to really show the benefits and show those who think it "bogus". Basically a back to back test with the stock cast OEM Keihin PWK.
People are extremely curious, and if there is Something that can boost the two stroke engines, peoples eyes and ears opens up.
If you can gain any advantage over the stock application it is a win win.
@@mikebrown41182 I will let Derek know and next time he has a stock bike in the shop, maybe he can do a dyno with the only change being the STIC
@@Shaw413 That would be really nice 👍🏼.
@@mikebrown41182 Actually from my experience, exhaust is very mild in comparison to the STIC. In fact, think of combining every bolt-on, same outcome. It can be tuned to a point where it's difficult to manage from off idle to lower mid-range.
I understand that there is no way to imagine the performance potential. Imagine a 125 with an exceptionally broad powerband and low end that doesn't want to bog or stall out. No cylinder and case work will do that.
Thanks for the mention guys!
Thanks for the support, ill be reaching out soon as we need to restock our hardware supply, and your the go to choice
Me being well on my way to being an old geezer and having my first good bike being a 1985 YZ125...... I think this throwback look is an awesome representative of the 1987 YZ models 👍
The rims look awesome, 1001 times better than
black rims. Great looking bike all around.
Congratulations with main event in Atlanta! I was screaming like crazy on last laps of LCQ! Heelclicker was sick! Support from Russia! 🇷🇺 2-stroke for life!💨💨💨
Thata a sick 2smoker wish they would let them race 250 2 stroke in 250 class
still be the same result
250 2 stroke would kill 250 4 strokes why you think they don't let em race that class!?
@@rebelyankee4458 if u think that a 250t would beat the 250f around the sx track you are crazy. The displacement rule was ok back in 2000 but not now the 250f lap times are almost identical to the 450s.
@@rebelyankee4458 for example the 250t that maid the main ran a consistent lap of 1.36 where at the top 5 250f were running 1.30 there a whole 6 seconds quicker than him
@@vaughanhodgson yeah but if they were on a 2stroke they wouldn't look and sound so gay..
This is one of the prettiest bike builds i have seen in a long time. Fully decked and looking ace as well! Congrats on your main Jared!! keep it WFO
Great video Jared!! Congrats! That bike is a beast!
This is one of the better inside videos compared to the factory mechanics(they all say the same thing lol)
Yep, the say the same things and tell us very little
that we can actually apply or use.
Best looking retro YZ I've ever seen. Followed closely by the Yellow and black Hurricane graphics from the '00s
I was at Indy cheering you on brother. That bike sounds great and looks so awesome. Your lcq race was really good I watched you blow by at least 5 to 6 guys. You ride that bike very well.
This kid is so talented it's unreal, I look for him to expand and keep growing and making more main events
Easily the best looking bike on the supercross circuit.
We have a 86 yz 125 with the red n white on gold rims. Love the color scheme. That looks closer to the 87 but still very cool
Incredible detail throughout this awesome bike !! Seeing you (and every other 250-smoker mounted guy) getting pulled off the gate makes me think that the 300cc displacement would be about right to make the fight more fair. Keep up the great work, guys !
I think we have to make it 1:1 honestly. If there’s any difference it can’t be equalized through easy numbers like 300:450
Sick work guys, that bike looks amazing, to the parts the complete build is what a bike should be today, 2 stroke for life…Make MX great again, 2stroke all the way..
Prob already know it but in the corners line option and carrying speed in and out is where that 250 should excel over a 4t esp the 450, good luck hope to see you in the main soon, where it and you belong, crush the enemy and drive them 450 into the ground, real men ride 2 strokes. 🤘
That bike is so fricken cool
What an incredible throwback beauty! 👌🏼Nicely done gentlemen. 👊🏼💪🏼
Sweet bike ! I love the color scheme. Had a 88 that I loved
Derrick does my suspension. He's great!
Beautiful work of art good job fellas. More impressive then a factory 4 stroke thats for sure!
Congrats on making the main in ATL!!
Seen lesher race this bike at kicker arenacross in Salem, VA..... It's a bad ass ride and he is a ripper on the 2 smoke
JARED YOU ARE ONE SMARTEST MOTO DRIVERS OUT THERE 2 STROKES HAVE THERE PLACE IN SUPER CROSS & MOTO CROSS . LONGER OR SHORTER PIPES, SILENCERS, FUEL INJECTION, OIL INJECTION, NIKASIL chrome bore CYLINDER , CRRECT PORTING, BOYSEN RAD VALVES & REEDS , EXHAUST POWER VALVES, THERES A LOT ONE CAN. DO . MY BEST MODS WERE HAVING THE SUSPENSION DONE BY AN AFTERMARKET COMPANY LIKE PETERSEN PRO SUSPENSION OR PRO CIRCUT, ADDING AN A SMALL SPACER BETWEEN THE CYLINDER & PIPE, TIRES DUNLOP, A STEAHLY HEAVY FLYWHEEL WEIGHT, SO YOU CAN HOOK UP BETTER THAN A 4 STROKER, BOYSEN RADVALVE & REEDS, TWIN AIR FILTER. THE LAST IMPORTANT THING TO GET IS NEW BRAKE PADS , ATTITUDE, YOU GOT TO WANT TO WIN. WIN WIN WIN .ATTACK THE TRACK, THE RACE IS FROM CORNER TO CORNER, THE FIRST CORNER TO THE LAST, “ BE TO & THROUGH EVERY CORNER FIRST “ !!! The BIKE LOOKS GREAT, TAKE CARE OF YOURSELF & YOUR BIKE, HAVE A GREAT SEASON ..
Glad you guys did this before atlanta where he finally made the main event... Go lesher
This Is the review we all wanted.!!
I had a 1987 YZ 80 , my second bike.🤙
Lucas Oil Stadium Indy... Worked for a company, that needs to remain un-named.... One block away.... Spent a 36 hh shift during that Super Bowl... Fun times... People watching was awesome!!! 36hr sh9ft, one of the best experiences EVER!!!!
This thing looks sick
Very nice setup. Even better is the fact that this guy has the skill and works his ass off to keep up with the much easier to ride 4fiddys. Kick ass
NEVER GO 4STROKE!!!
2SMOKE4LIFE
So clean!
4:05 Love this engine, never been a fan of the
'coveted' ring a dinga dinga ding ding that everyone else
loves so much, nope no fan, but look at that motor and how
much simpler they are to work on. I would never even begin
to complain about having to mix fuel.
I'll take ringa ding ding ding over hearing a 4 stroke limiter anyway (the ugliest sound in moto)
@@surfingawaveoflife Contrair professor,
the ugliest sound is blowing up the
engine, plus, maxing out rpms in jumps
can save your life, literally, and not
at the expense of a blown motor.
I prefer the two stroke in a dirt bike,
for multiple reasons, but
the sound is not one of them.
Dope build boys gotta love an underdog story 🤘🏻
Id like to know more about the CDI. This is basically the same as a factory bike just without the factory support. Easily a $30k + bike
It is a GET CDI, programmed with 2 maps by the engine builder.
I'd love to see the dyno sheets on this beauty
250 2 stroke against 250 4 stroke., fair comp., 450 2 stroke against 450 4 stroke fair competition, anything else is BS.
I’d like to see a 300cc 2t have at it with the 450’s even if the rider would do it without garnishing points
Damn!!!! SUPER sweet bike! Wow! ❤❤😮😮 🔥 🔥
What’s up Michael, You we’re telling me about the bike in Arlington when I was admiring it and telling you that I had a 1986. Still looking good. Rooting for y’all each week.
Thank you for the support!
Well Lesher just got one more fan. Ill be looking out for the 412!
What year frame, and engine are you using?
Also, what fuel & oil do you use? Do you change either for elevation?
Do you have a gofundme? I'm sure many of us would donate to help keep ya racing, & representing the many 2-stroke lovers.
2023 they said. But it is virtually the same since 05.
Wonder why I remembered their sponsors even though they aren't tractor pulling podiums.The coolest bike out there might have me give a shit to actually watch.
Wishing you as much luck as you need...I started riding and racing 2-strokes back in 1973 and even though I have a couple modern 4-strokes(which are nice) I still seem to prefer any of my garage full of 2-strokes... something about the sound and feel just makes them more fun. It's a real shame the racing has gotten away from 2-strokes...just the cost of maintenance alone makes it tough for up and coming privateers.
Yah...when your hitting the powerband and running through the gears. The 250 2-stroke is a rush.
I grew up on 70's bikes as well. Remember laying down and forward mounting the rear shocks. lol
@@redphantom70 absolutely! It was such a cool time... everybody was trying everything. Love it.
Speechless over here… 🙏🏼
Displacement rule sucks. Should be open. For godsake 450's HP/torque numbers are insane. What does it matter?
they do suck but put the 250t in the 250f class and it still struggle to make a main
@@vaughanhodgson Keep showing your ignorance. It’s hilarious. 🤣
@@SPCRacing1 it's not ignorance it's facts
Keep it lit my man! Rubber side down.
I would love to see the 2 strokes ripping against the 450 bikes in a pro race
Yes, definitely. Theye got the 300 2t's out. Would like to see a 350 fuel injected 2t. Should be competetivee against the 450's.
@@Corteum a direct injected 250 or 300 would be revolutionary. No more premix, just shoot a jet of oil up to the bottom of the cylinder to spread out. A small supercharger on a 2 stroke could also remove the oil premix and oil burning. Once they do that, the 2 stroke will make a huge comeback and possibly come back to the pro series racing.
If @AMA wasn’t such cucks with displacement rules we would already have had the 300sx and tx300 in the 450 class with 250 smokers in the 250f class like they do across the pond in Europe .
@@_WatsoBrii94_ yeah the whole story of how the 2 stroke got fazed out 25 years ago really sucks. They did it for no reason. They basically made Yamaha cheat by using the 400 4 stroke they made specifically to beat slightly modified 250 bikes. I really just want to see the 250/300 compete with the 450 class and the 125 compete in the 250 class. The power to weight levels are basically the same, and that's how racing should be classed, power to weight.
@@joshlewis5065 I like the sound of what youre saying. So the direct injection is even better than fuel injection for 2t? Is anyone else playing around with the supercharger idea? sounds like the ticket we need
We need 1 thing here.
1. Flywheel weight size?
2T’s are awesome. Hope to see it in the main. We’re cheering for ya.
Its the GYTR flywheel from the YZ250X. It's +8.04oz
@@Shaw413 Thanks for letting us know!
Congratulations on making the main!!! So rad!!!
thats awesome. good luck dude!!!
Please show off more of these bikes!
Dopest graphics ever
Should be racing the the 250 class! It's bull shit, they make you race in the 450's.
still would be the same result
@@vaughanhodgson Clueless
@@SPCRacing1 how it's true. Look at the 250f lap times there pretty much identical to the 450s. In fact with jareds lap times last weekend he would of placed outside the top 15 in the 250f main
the first real motocross bike ive seen since the late 90s
1987 replica 😎😎
412 represent, pgh hardest workers in dah game
freaking sick bike.
Fantastica ..complimenti!!
2- stroke: Throwback build.
4-stroke: Throw away build.
Two stroke motorcycles Awesome!!
Yo he put that thing in the main today
Gorgeous motorcycle 😍😍😍👍
That is a beauty.
The Best bike Is the 2 stroke
WORKS! 🤤
So awsome man 2 stroke 🤙👌
Reminds me of my first YZ125... But far nicer in every way and the 250 helps too. Harris isn't too far from where I live.
Put a 300cc in it!
Way to go getting it in the show last weekend.
È la num 1 la yz fantastica meravigliosa 🙏🙏❤️🙏❤️❤️❤️❤️🙏🙏🙏🙏❤️❤️🙏💋☮️💋💋☮️💋💋💋💋💋
That bike is nice
Love it! I want one. Great job boys! Keep at it PLEASE
My hats off to these remnant hold outs for the 2 stroke community
Absolutly sick bike!!!!
If you like 2-strokes motocross... stopp buying 4-strokes!
It is that simple!
Even more, since over 20 years I only buy an entry ticket for a race when a 2-stroke class is on that day.
All the best for the best sport in this world!
Beautiful.
Amazing bike,very Nice!
One HELLOFA bike 👊✌️😉
Beautiful machine lads😍
Che moto chissà cosa darei x avere una moto così splendida guarirei da tutte le malattie 🦠
These guys know whats up!
DUDE IM A HUGE FAN!!! #412 for star yamaha
Two strokes ❤
sweet build.
They really need to let 300 (kit or not) 2 strokes in the 450 class. But they won't cuz they're scared (and goes against a narrative).
Didn’t alessi race a 360 or something a few years back?
@@dirtjump132 I think it was a 325 in the monster cup (non AMA). I don't think AMA allows for anything over 265 (2 stroke) unless it's open class.
I hope he does Good,I’m a 2 stroker All the way…even tho I Just Bought the CRF 50th Anny🤣,I Still have my 06 CR125🦾…I’m Hoping to buy a 1986 CR 500 from a Friend & will put the Motor in the 450 Chassy ! 2 Strokes Forever🤑🦾🔥👽
Kinda a strange name for the oil, "Blud Lubricants" bunch of gothic stuff came up first till I found their website
Excellent.
Awesome ride in Atlanta keep it up!!!!!!!!
Boss bike
