I was looking through my December 2000 issue of dirtwheels, and on page 163 there is an add for CT's Boring, Machine&ATV Repair, and on the bottom of the add it says "Home of the 70mph TRX300 4X4".I think that getting 70mph out of a 300 4x4 would be very difficult because you can't change the gearing because it is shaft drive (I guess you can by changing tire size, but the big tires are heavy, and tough to pull). The only way I could see this happening is if they put a bore kit on it, with huge light tires, and got the engine to rev to 14 000RPM!!

 

CT racing is experienced enough they could change the gearing on the shaft.They could also stroke, port and bore it.

 

off a cliff in a high wind perhaps........

 

CT racing or FST did a trx420 4x4 that did 70. 4 wheel atv action did a test on it im the june 99 issue i think it had 25&26 in tires it was ported and bored, w/ a cam supertrapp and k&n and was rejetted if i remember right. it had some accessories too but i think thats all thaT was done to the motor

ummm you have 250r pro pegs???? how did you get em to fit?

 

welded tubing to the frame like the laegers frames have then they just slid on but they are not mounted by the motor mount i had to make a bracket

 

it is very possible a capable performance shop can do almost anything. Wow that would be scary I hope they added longer travel suspenion. pogoing at 30 on one of them is scary but 70 !
