exhaust Yasuni Cross HM MAX aluminum for Aprilia RX, SX, Derbi R, SM, Gilera RCR, SMT YA233X

With the Cross HM MAX exhaust Yasuni has bridged the gap between performance and practicailty in a moped exhaust for 50cc or 70cc bikes. Coupled with the excellent build quality from Yasuni and the wide range of applications, this system is a very good choice for those who like a little more grunt, but aren`t interested in outright maximum power. Performance-wise identical to the SPR3 or HMR2 system, but with headers and cylinder in motocross style. The overview on Figure 2 allows a better assessment of the applications of the Yasuni Cross HM MAX exhaust system. This tuning exhaust is equipped with a high-quality, aluminum silencer. All parts required for installation are included. Fits different mopeds with Derbi and Morini engines. 28mm diameter outlet
