The owner's manual does state:
Change the piston: S105A: Every 105 operating hours/every 50 operating hours when used for motorsports
The question becomes, then, what is 'motorsports' use?
Interestingly, the manual calls for the following items to be replaced at that same interval:
Change the connecting rod, conrod bearing and crank pin.
For the 105 operating hours, this could occur between 2000 - 6000 miles, depending how fast you ride (20 - 55mph)...
I wonder how often these parts changes will actually happen...
