Ok Stig,
Every things seems to be good. I followed the owner's manual for servicing. Plus almost every Sunday morning, I check the oil and tires. My tires seem to lasted around 8500 miles. Brakes lasted about 17,000 miles. The belt lasted about 17,000 miles. The body has held up real well.
The only major issue was when Downie quit running back in October. My mileage around 37,670 when that happened. Moxie's replaced the valves and piston but never really determined what caused her to quit running.
Other things that have happened: One of the cables used to unlatch my seat broke. My left rubber foot pad broke. The battery lasted about 2.5 years. One of the screws used to keep the brake handle fell out. The small muffler protector has fallen off twice.
