Decreasing the tooth count (e.g., from 16T to 15T)
This creates lower gearing, causing the engine to rev higher to reach the same speed. Effects include:
Quicker acceleration and more responsive throttle feel.
Lower potential top speed.
Increased engine RPMs at cruising speeds, which may reduce fuel efficiency.
Increasing the tooth count (e.g., from 15T to 16T)
Reduces low-end torque but improves top-end cruising speed—ideal for riders seeking better highway performance.
