oh ok i only assume y15/rs speed....anyway ninja 160km/h still slow
so TS better go straight for >500cc bike

The problem with big cc bikes for newbies is the throttle response sensitive due to big power. Example if masuk lubang and your hand tertwist the throttle a bit... Small bike just bunyi bising but no sudden surge forward if that time gearing is correct.. if big cc bike the accident will cause the bike to surge forward and well...lose control.
