03kidzdirtdad Posted December 18, 2015 Just bought my son 2012 ktm 50sx. Bike seems to run good for now. Looks like these bikes require a lot of up keep. He just started racing at the end of last season with his CRF50 and was begging to upgrade his bike. I want to get him some good seat time before racing starts up in April. The bikes way faster then what he's use to. Looking into replacing the clutch and top end before then. Not sure if it's ever been done on this bike I bought. Was looking at the IRP clutch to replace what's existing. Any input out there on the IRP clutch and any good maintenance program to stick to to keep the bike running solid? Thanks for the help Share this post Link to post Share on other sites
