I think, (but hey, what the hell do i know!) a 4 cylinder bike should hold together better than a twin,
many people have campaigned the twins in the past, Mcguinness & Rutter for a start, with a slight amount of success, so , fingers crossed he'll be up there. It''ll make a nice change.
Then again, my experience consists of many years riding Harleys & Triumphs against a year or so on a Honda 4, so, for me, the difference is, shall we say, marked?
