After some advice on what to look for when checking out a second hand bike to buy. Having a look at a 2009 C109rt next week. It has 28,000 km on the clock. Any known issues with this model?. Already done a REVS check & all is good. Have enjoyed riding the C50 since I bought it last year but it is a little small for me & I think it is time to step up to a bigger bike. Hopefully the C50 will have it`s big brother parked next to it in the shed by this time next week!
