I too am very interested in the new 500, as a 'lightweight' replacement for my 690R, but am concerned with the service intervals for the 500 as compared to the 690.
For example, the service sched. the dealer printed off for me showed 130 hrs. for a piston change (50 hours under competition conditions).
BTW, are you a time traveller?
