My experience has been that most motorcycles are geared to achieve the highest top speed possible .That said I expect big displacement cruisers are over driven for many reasons , mileage , comfort , who cares about performance when a 500 twin is going to zip by them anyway. Suffice to say many big cruisers will go faster in 5th than in 6th , much like your car which would probably do 150 mph easy if it could get to redline in high gear, but it can’t , it’s way over driven , that’s partially responsible for how it gets such good mileage despite weighing 8 times more than your bike and it’s engine 4 times the displacement. My point being Dave . If you’re 360 Enduro coughs as you approach a stop while down shifting to 1st and when release the clutch to proceed it goes backwards . 1 release clutch again slowly . 2 if goes backwards again. 3 shut of the engine , restart proceed forward .
