101 OCTANE is a brand specialising in standard, performance, and tuning parts for Chinese scooters and mopeds.
Most Chinese scooters such as Baotian, Lexmoto, Direct Bikes etc. use basically identical engines for all engines.
Normally the 4-stroke Chinese scooters will use an engine based on the GY6 engine and are available in 50cc or 125cc. There is also a common 2-stroke 50cc engine used in Chinese mopeds which is based on the Minarelli horizontal engine as used in Yamaha Jog etc. although there are a few important differences in the spare parts it uses.
