Will a CRF450 motor fit in a TRX450 Frame?

[rappin_ernie]

Anybody know if the motor mounts are the same on the CRF and TRX450 motors? Thanks a lot!

I do not know, but I am willing to bet the motors will fit in 06 up frames much faster and easier than the 05 frames.

it seems the dirt bike engines sit up higher than the quad ones, this is an opinion by looks so just hope it helps

[rappin_ernie]

Yea, I'm not quite sure. I'm thinking about buying a houser 400ex frame for a crf450 motor, and I want to see if a 450r motor will fit as well, I know they are very similar.

[fastredrider44]

Ask houser. They will probably know.

I was curious to something similiar would a trx450 engine bolt up into a crf450 hybrid frame? i figured it would noit be exact but was curious how close it would be

I'm not 100% but my best guess would be 06 and up trx motor are alot closer to crf motors than the 04 05 motors I bet it would be more trouble than it would be worth. If it was me I would just sell me trx motor and buy a crf motor.
