I'm running a Trail Tech stator (100 amps), but was looking at their web site and see they have a +17 ounce fly wheel, I pick up 20 amps, and it supposedly makes the 450X a tractor, is anyone here running one and what are your thoughts? The tech guy at Trail Tech, says it almost completely removes the hit, and makes it a smooth transition into the power, stalls less, and lugs like no tomorrow. The article in Dirt Bike Magazine got me thinking about this, on their project 450X. Thoughts? To much?
Thanks

That sounds like alot of weight to me. Try it out and tell us what you think.

I ran the 6140-35 trailtech flywheel on my crf450R (+13oz on my 02 or +17oz on 04 and later.) It slowed down the rev noticeably, but really had no negative affects for me being that I ride desert and offroad, never at the track. Offroad it definately gave me some warning before a stall, giving me a chance to save it, instead of stalling instantly and unpredictably like it did with the factory flywheel. It basically let my 450R lug more like your 450X does stock (much better), so it should be a worthwhile upgrade to your X. If you ride tight trails and are stalling often, I would definately recommend getting the heaviest flywheel you can get your hands on.

but you still dont want to lug a short skirt slipper pistion engine very much if at all.

True, wonder if there would be further advantages of running a TRX450 piston in the X?

i bet it couldnt hurt, the added weight of the trx and the fact that quads are easier to mistakenly lug is why the second ring and longer skirt would help. I havent seen a side by side photo of the 2 pistons though, would be intresting for sure!

I went with a Trail Tech +17 oz flywheel, and love it. I ride almost all woods that range from fairly tight to really tight. Initially, I worried that +17 was too much, but that's what was available. Combined with a G2 throttle, the bike is now fun in my home environment (I was close to going down to the 250X).
Maybe the "hit" is gone, but if so, there sure is a huge "surge" remaining when the revs climb!
For my riding style and environment, I'd install a TRX piston, but only if I was digging into the motor that deep for some other reason.

sorry to steel this post so late guys... just wondering about the bigger flywheel for my 450x... its bone stock right now... and I stall it a lot down low... if I went to a heavier one would i still need to rejet?

I don't believe the TRX to have a longer skirt as others on here have said. I haven't measured them, but see for yourself. If it's any longer, it's minuscule - but I think they're the same length.

As you can see the TRX piston adds a 2nd compression ring.
I have the +17 flywheel. It made the bike much easer to ride in tight woods and not stall when crossing logs and such. It still has a lot of hit and will spin the rear tire if you whack open the gas. I like it, it made the bike ride more like the orange 4 strokes I have rode.
Yes you still need to rejet. Rejet is the first thing you should do.

try a hinson stainless steel clutch basket, I rode a WR450 with one.... wow! very cool setup! Similar to a heavy flywheel.

You stall because you need to re-jet.

Thanks Krannie... since I need my exhaust intact can I rejet and cut open my airbox but leave the stock exhaust? I have alwasy been told you need to do all three? So I have left it stock...

Why do you need your exhaust 'intact'? You can remove the restrictor without altering the nature of the exhaust, making it only 6db louder.
You cannot open the intake without opening the 'outtake' of the motor, but you can remove the snorkle.
Even if you don't un-cork, you still need to rejet.

Thanks... I think I need the exhaust intact for the spark arrestor????
Cool, rejet I shall do... i will get back to you and let you know what I think!!! Up here we are still about 3 weeks away from being able to ride

just wondering ? why not lug the 450x engine...thought that was a perk of 4 strokes

Asked and answered: Slipper piston motors cause piston rock, which is highly aggrivated by lugging the motor.
You can lug the motor all you want if you don't put a heavy load on it, like WOT in a gear too high, climbing a hill.
