Hey guys/girls, i was wondering what the deminsions of the Ninja 650R swing arm is compared to Ninja 250R. I saw the whole right-up about how to swap the bearings, hub damper, rim, sprocket, ect. while keeping the 250 swing arm, but that looks like a lot of work. Especially, if it is possible to swap the WHOLE rear end! Please let me know if anyone has any information! Thanks Corey
