trx70 4 speed

I have a complete trx70 4 speed transmission with shift drum and shift forks. I also have a parts trx70 tranny that is missing 2 gears (i think it was second gear from both shafts). I am open to offers, I don't have any clue as to what these are going for now. my email address xfrstunna@yahoo.com

Re: trx70 4 speed

I'm interested in the 4 speed. I have a CT70 motor that's got a broken tranny and is stuck in 3rd gear.

How much shipped to 94550?

I'm pretty sure the trx tranny will only work in trx cases

They drop into a crf50 bottom end and match up to the kick starter and everything. I had a stock motor apart and dropped it in to try it and everything fit. I was going to put it into my 108 but I sold the bike before I had the chance

I've got a TRX70 tranny and an '05 CRF50 bottom end on the work bench right now. The 70 trans (mainshaft cluster, countershaft cluster, and shift drum assy) is a straight drop in. First gear is identical on the 3-speed and the 4-speed (36:11) so the CRF kick starter shaft assembly will mate properly with the TRX trans. Great upgrade, and worth the $$ for original Honda parts.

(I've got three 4-speeds in boxes right now, otherwise, . . . )

Re: trx70 4 speed

So it's not a drop-in for a 6V CT70 motor then?

Re: trx70 4 speed

Yes, it will work in the CT70 lower end as long as you have the 22T pinion gear on the kickstarter spindle. The CT70H model with the factory 4-speed has a 24T pinion gear, and is only compatible with the CT70H trans.
