I am building a 250r from scratch. i dont know what parts will swap from all years. it will have a r6 motor so i dont need to worry about that stuff. its an 86 frame, will a-arms, swing-arm, hubs, steering knuckles, etc, from other years fit corectly on my frame. i dont want to come across stupid, but i have been a cr rider all my life and am not to familiar with the trx.

thanks

 

Most all parts are interchangable from 86 to 89.
