trx 125 interchangeable engine parts

[618kustomz]

i know its not a 3wheeler, but i know u guys have an answer. im building a quad. its a trx90 style frame. i rebuilt the front end, widening it 5 inches, build a 19" extended swing arm and put an old 85 trx 125 engine on it. this thing is wicked, but y stop there? time to overhaul a perfect motor. i am looking for performance parts the will work on this horizontal engine. i know there is a butt load of 110 hop up parts out there, ive done had my fair share of that. but the 125 has a bigger bolt pattern for the jug. im looking for big bore, stroker, 3 or 4 valve heads, that kind of stuff.. is the chinese 125's the same jug bolt pattern? does anybody know that one from experiance? any motors that the parts are interchangeable from? anything would help.. thanks ev body.

nothing for the TRX125, I think you can make a hi performance 90/110 cam work but not sure, the person who know is on here. If you started with a TRX90 the chinese mootrs bolt right in and you can go real big like 150cc's. Good luck and welcome.

While i can't help out with the trx engine, how about modding it far enough to mount a yz250 engine/coolors and tank on it? that would be considered highly modified and intoxicatingly fun and fastttt.

Nothing chinese will fit the TRX/ATC125 engine.
