sled vs street bike for hp build?

[capulin overdrive]

Would you rather scalp a sled for a build, or street bike?


Sled seems the cheaper more practical route, especially if the sled has a good skid.

A lot will depend on how you plan on driving the jack shaft from the motor, the bike engine has a clutch and a transmission that will work right off the hop, how would you drive the jack shaft wit the sled motor? Their clutches are pretty big and in a bad spot for the riders feet if the motor is placed conventionally.

Personally I have always thought a 600 etec motor would be a nice fit.

Know the sled route would be wider. Was thinking raising up the motor, and hopefully narrowing it up?


Right now I'm just dumb enough I'd like to try a build, but would like to hear from those who have tried already.

Narrow a sled motor?? not sure how your gonna do that. But could be possible to run a chain back and mount the clutch on the inside instead ON the motor making it wider. Many options you could go with.

This thread has the best snowmobile based build I've seen to date. Give it a read and maybe it gives you some ideas. http://backcountryrebels.com/showthread.php?t=30436

Thanks for that link.^^^^


Learned enough from that, to tell me I'd be better off trying a street bike build with tools I have on hand.

Look around for some Hillclimb dirt bikes that have been built with sled motors all ready or street bike motors there usually pretty cheap

I'm in the middle of a R1 RAPTOR project and have owned and sold another R1 Raptor. I think these engines would be very feasible. They are reasonably light and narrow. In a raptor your pegs stay in the same place. It may be something to look at in the future. If I was to do one it would probably be a 2001-2003 because of less electronics even though they were less hp. they had higher TQ! They would be easy to graft into a bigger chassis like a cr500 or big 4 stroke chassis.
