l am trying to see if any one may know if the presure plate hole's line up from the trx250r with the 400ex clutch presure plate or if the trx450r or er 5 hole will. the reason i am asking is i am looking to try and come up with away to make a lock up clutch by using axr400 clutch cover . any info would be great, thanks for your time and happy thanks given to the atv riders.com

The closest thing to a lock up clutch your gonna find is the cbr900 plates and fibers.

I just bought a new frame, sub frame and a arms for a new drag cut frame build.

Moving the hybrid to this new frame when its done, then re-building the EX frame for a "hot rod" style build

If i can get some one with a 450r and a 400ex pressure plate to let me know if there the same or is the 250r plate hole are the same as the 400ex i can build one.


Does any one know what the measurements are hole to hole on the 450r and the 250r so i can check them with the 400ex plate?

Thanks.
