TTR to KX or KX to TTR

Recommended Posts

I have a friend who is hooking me up(for free :applause: )with a '99 KX80 rolling chassis, no motor. Should I, #1) Transplant the KX front end over to the TTR-125, or #2) transplant the TTR engine into the KX frame ?

Decisions, decisions......

I would put the front end on the ttr instead of the engine transplant. To me, it sounds easier with less work, time, and money. Hope this works out. Post pics when you're finished. :applause:

Been Contemplating too about the Idea about of putting the TTR Motor in a KX 100. I believe that the KX 80 Chassis has a 17" front wheel and 14" rear wheel, but still good. Has Disc Brakes front and rear and a Full Cradle frame. If you do the TTR motor conversion into the KX, Don't forget Pic's . Sure would like to see how it turns out.

KX forks will go on the TTR. I would go the other way, drop the motor in the KX frame. Better geometry, brakes and it should be stonger (unless you have to hack it up for motor install).

I would definitely put the ttr engine in the kx frame or better yet find an old kx engine on ebay and put that in. Good luck with whatever you do.

I'm at the end of my TTR days. Everyday, I wish i had a better chassis w/ better suspension. i could have opened the air box, rejetted, got a lighter cam, different exhaust, $160 on BBR springs(or 'fat-people pogosticks', as I like to call them) and about as much money as I want to spend on the engine. But I haven't done any of that, all b/c the suspension, and chassis are not up to par. :applause: The answer should be obvious.

There is a dyno at the bottom of that page.

The point is, your getting bigger, stronger, faster. You can always do something to the engine, it's the suspension that can not keep up. REMEMBER "The chain is only as strong as it's weakest link." I wish my TTR had clickers, and adjustments besides preload.
