Maverick Motor 23T Pinion Gear (0.8 Module) Use the Maverick 0.8 Module pinion gears to change how fast your Strada Evo or Evo S kit will go! With a smaller number of teeth on the pinion, you will see faster acceleration but a lower top speed. When you use a larger number of teeth, your Maverick Strada Evo or Evo S kit will have a higher top speed but will be a little slower.
