hi guys and gals not been on here for a while my nephew as a rr9 about a week ago he was riding it very spiritedly then all of a sudden it slowed down on him like it went in to limp mode so he couldn't ride it back home and had it get it picked up ive been up to see the bike today it starts up fine no bad noises engine runs fine but when you pull the clutch leaver in and put it in gear and let the leaver out the rear wheel hardly moves its like you have still got the clutch engaged any ideas anyone I think the clutch as gone?
Sounds like the clutch has failed/slipping. Unless you have final drive/ gearbox fault. But as youce said no noises my first port if call would be clutch.
