Product details

Optimize your mini-bike's transmission with this 72-tooth reinforced crown. Unlike standard models, this version has undergone a specific heat treatment, giving it a hardness and longevity far superior to original parts.

Performance tip: Most Pocket Bikes come with a 68-tooth crown. Switching to a 72-tooth model gives you better acceleration and more pickup when exiting turns, ideal for winding circuits or cross-country terrain.

Technical Characteristics and Dimensions

This crown is designed for 3-point fixation hubs:

  • Number of teeth: 72 teeth.
  • Chain type: Small pitch (reference #25).
  • Spacing (distance between points): 6.5 mm.
  • Central bore diameter (hub): 26 mm.
  • Fixation: 3 holes.
  • Thickness: 3 mm.

Vehicle Compatibility

Thanks to its standard 3-hole format, this crown fits a wide range of machines:

  • Pocket Bike Racing and Supermoto (including Polini models)
  • Pocket Bike MTA4 and MT4 (liquid or air cooling)
  • Pocket Quad and Pocket Cross (depending on hub mounting)

Why choose this reinforced version?

Transmission is one of the most stressed points on a Pocket Bike. By choosing a crown that has undergone a different heat treatment, you limit premature wear on the teeth and reduce the risk of derailment related to deformation of the part.
