Wade and I spoke yesterday, and he told me TGB has sent some 150cc scooters for EPA testing. My guess is the two 50cc 2-stroke bikes, the Key West and the X-Race, will have 150cc 4-stroke bigger brothers soon.
We were also discussing Hawaii, and the 2-stroke engines actually work against TGB--the vast majority of 49.XX cc engine scooters are classified as mopeds for easier licensing purposes, but since the 50cc 2-stroke is rated at just under 5 horsepower, they can't be classified as mopeds. My guess is other states would have the same issues, but Hawaii is a HUGE market for scooters. Too bad TGB won't make models utilizing 49.XX cc 4 stroke GY6 motors supplied by a Chinese company. The scooter itself is solid as compared to Chinese scooters, and the Chinese engines have proven themselves solid provided you change the engine and gear oil (although there are exceptions to that rule), so a moped for all the moped states would be a good low-level bike TGB bike. You would probably spend more, but have to worry much less about losing parts like you would on Chinese scooters
