Keith, I totally agree with you about the ten being a great winter bike on tarmac, inc wet lanes, it's the more off road side of things I'm talking about. Sure, an experienced off road rider could hustle this bike with the best of them but that ain't me! The R feels a lot lighter bike and I suspect if you stripped both bikes down to the chassis they'd be pretty similar. Hence wondering whether it would be feasible to change some parts.
Probably more trouble than it's worth. Maybe I've answered my own question!!
