Cheers guys...I think it's deceptive with the Tenere as despite the on paper BHP it's a big single with lots of 'grunt'....and quite hard on chains. Which as we know are only as good as the weakest link!.
Chalk Two... I think the side to side movement after the split link departed and all the extra play just chewed up the teeth on the sprockets, especially the rear Renthal superlight which is hard anodized aluminium. Cheers, Steve
