High Performance Carbon Fiber Zuma Reeds! ('02-'11)

  • Easy to Change
  • Great Throttle Response
  • Stock metal reeds break=big engine damage!


The Reed Story: the object of any tuner is to increase the power of the Zuma. The trick to this fine tuning is to increase the power into a smooth USABLE powerband. Any of the above 3 reed sets accomplish this. The design of these reeds is to open sooner and stay open longer than your stock stainless steel reeds.

Opening sooner allows the fuel / air mixture to enter the motor quicker thus giving a higher mid-range and top end power gain. If the reeds close too quickly the motor will not develop the much needed top end power. An exact balance of reed tension is needed to assure the proper function of the reed system.

Malossi Reed Block

These are reed valves designed with flow corner and with calculated capacity section. The petals are made of a material composed of karbonite and carbon. They are manufactured with advanced production processes and with the use of raw materials carefully selected. These reed valves are designed for modified engines and they have been tested directly on race tracks.

Includes Carbon Reeds, Reed Stops and stuffer.

Malossi Reed Spacer

Spacer for Horizontal ('02-'11) Engine

Thanks to experience gained on racing circuits, Malossi brings a new 5 mm spacer for placement between the crankcase and the reed valve to improve the performance of the scooter.
