Akrapovic EVO FULL Exhaust Suzuki KX/RMZ250 2004-05

Since the Kawasaki KX 250F and Suzuki RM 250Z have the same engine, the Akrapovic EVOLUTION complete exhaust systems for these two models are also identical, both in configuration and performance. The EVOLUTION system is intended for professional MX riders, as its advantages are shown especially in the overrev range. In addition to the performance increase over the stock component, experienced riders will appreciate the weight savings, which count for a lot in lightweight MX bikes. The system conforms to the FIM 98 dB noise regulations for MX competition. Unfortunately, due to excessive noise levels the system in question does not conform to the FIM regulations for ENDURO competition. We have also developed an Akrapovic EVOLUTION complete exhaust system for the same motorcycle in order to provide improved performance (power and torque) at the lower end of the rpm range. This Evolution system differs physically in the dimensions of the header tube (see schematic). Regarding power delivery: see graph of the measurements for the Kawasaki KX 250F (2005). For 2005, the Kawasaki delivers more power than the 2004 model.
