I have been riding this bike for over a month,had washed the bike for at least 3 times and riden through heavy rain and floaded road. So far donĀ“t have any problem with engine stop or not running. The only set back about this bike is the body is too big for the engine and the clutch is rather soft, sometimes it feels like the driving a car with a worn out clutch plate. The rest just fine, design is superb just speed. I always imagine if I can ride this bike at 140km/h someday.
