I'm pretty sure these kickstands were all the same on Cats except for some of the bigger model Cats like the Wildcat (R3509), and some of the choppers like the Duster or Hustler (3503), and Endura (R4005). Those were slightly longer than this kickstand but this is the common Cat kickstand used on 400X, 300X, 400TS, 250X, Duster MX, Dominator, Eliminator, Slingshot, etc. models.
