To achieve swifter acceleration, consider employing lower gearing, which will shorten each gear and necessitate quicker shifts through the gears. Opt for a smaller front sprocket (countershaft) or a larger rear sprocket. Notably, altering one tooth on the front sprocket is tantamount to modifying three teeth on the rear sprocket.
| Rear Sprocket | Front 12 | Front 13 | Front 14 | Front 15 | Front 16 | Front 17 | Front 18 |
China Pit bikes are equipped with two distinct types of front sprockets, also known as countershaft sprockets. The majority of pit bikes utilize a standard or smaller shaft, measuring 17mm/14mm. This specification is common among various models, including:
In a 4-stroke engine, the gear ratio between the crankshaft and the camshaft is invariably 21 ratio is crucial for the engine's proper functioning.
