Parts easily obtained either from a dealer as JonW points out but also Motorworks, Motobins or James Sherlock all of whom I use and can recommend.

I think an R65 is a better choice than most here will, partially because I'm biased, but also because they are easy to ride, handle well and if you're into doing your own maintenance, very forgiving to work on. A friend of mine had an R65 as a first bike and now he's on a K1200RS having had a very happy transition. Good luck
