Original 42T-420 sprocket and 102-link chain set

Original Surron Light Bee X drive kit—sprocket and chain in one.

This kit is ideal for those who want to increase their top speed and enjoy longer, smoother rides in open spaces or on faster sections of the track.

The 42-tooth rear sprocket, paired with a 420-width, 102-link chain, changes the gear ratio—resulting in a higher top speed but slightly lower acceleration compared to the standard kit.

This is a classic trade-off between speed and acceleration—the choice for those who prioritize speed over explosive acceleration.
