The Motoforce Racing Evo reeds are designed to significantly improve air and fuel intake on Minarelli horizontal 50cc 2T engines, such as those found in Yamaha Bws Zuma 2002-2011, MBK Nitro, Yamaha Aerox, and several others.

Thanks to their performance design, these reeds allow for better engine responsiveness, sharper acceleration, and optimized intake flow.
