I am parting out a 2022 yz450f due to an engine failure. I have a few snow bike specific parts available. RP racing pipe, thermostat, forks with heavy springs, throttle body, most tranny parts are ok, cases are ok, clutch, levers, pretty much everything but some internal parts of the motor.
2022 yz450f part out
- Thread starter Lkabotoff
- Start date
Are the forks stock besides heavy springs? How much?
Yes, other than heavy oil and Ktm 690 springs. Probably $1000 cad. I looked online and some were as high as $1500
Just out of curiosity, what let go in the motor. How many hours? Thx

I think the wrist pin broke and then all hell broke loose. It needed about $4000 in parts. Under 80 hours
All I had on was a rp race exhaust. I would say the engine was at a normal running temperature. We had decent powder and I’d already been riding for about 15 minutes when it decided to let go.
I'm surprised the wrist pin broke, its a pretty beefy part. The YZ that blew up last season that we had to onsite swap the motor on, we think a clip popped off the piston but the pin itself was whole still. 1/2 of the bottom of the piston itself where the pin goes through is MIA. 80 hours is low IMO but I guess the lesson here is you can't always see if a part is good just by looking at it. I swap top ends every 80 to 100 hours, all the pistons always look fine but honestly who knows. Yamaha recommends a new piston every 20 hours in full race conditions which seems a bit excessive but still.
When even the average guy rides a snowbike he can torture the motor as much as a pro MX rider ever does. The bikes are just too fast in MX, nobody can hold them pinned on the rev limiter for as long as Joe Average snow biker can. Plain and simple, its hard on your bike. In order of desirability when buying a used bike I look for. 1: Old dad trail bike 2:Race bike 3:Snowbike 4:Sand bike.
