Maybe the cynic in me, but the Chinky I had, the warranty was worthless, even when serviced to their schedule.
Headstock bearing went at 1,800 miles, WK refused the warranty work, said it was a consumable part, yeh, but not after just 1,800 miles, the nice guys at the shop stood to the repair bill, they did another service, then I said bugger it.
My scoot holds 1 litre of oil, no oil filter, spark plug a doddle to get too, same with the air filter, that's all mine needs on a minor service, doubt I will ever do the milage to get to a major service.
