GY6B Drive Plate CF Moto E Charm SYM HD200 CPI GTR 150 ITA 150
ITA 150 BMS Pathfinder
Scooters with 16 inch wheels and the longer CVT that use the GY6 125-200cc engine use the larger 123mm variator and 20X15 weights.
I had to name this engine in 2006 when the E Charm came out due it was a GY6 engine just larger in the head and CVT and LC. The Air Cooled models are the ITA 150 and BMS Pathfinder so I named them GY6B. Just like I named the GY6 50 139QMA/B
