Yoshimura RS-12 Exhaust System Kawasaki KX250

Yoshimura introduces the RS-12 Signature Series full system exhaust, designed to enhance the performance of the latest Kawasaki KX250F. This new evolution of the motorcycle features an upgraded chassis and engine, and the RS-12 exhaust has been fine-tuned to mesh seamlessly with these advancements. Extensive development has revealed notable improvements, including an increase of up to 3.3% in horsepower at 11,000 rpm and up to 3.4% in torque at 10,600 rpm. The result is a significant boost in power delivery across the top end and improved throttle response throughout the lower and mid-range of the power spectrum, propelling the 2025 KX250F towards victory.

Features:

  • Our new Carbon Faced Machined Joint eliminates the need for anti-seize by impregnating the surface of the stainless steel joint with carbon atoms, reducing friction and wear over the joint's lifespan
  • Our header resonator isn't just there for looks, it allows us to maximize power across the spectrum, while enhancing rider connectivity
  • Our new RS-12 for the 2025 KX250F comes with an INS-31-K sound insert installed for an ear-pleasing exhaust note and optimal power, with an SA-21-K spark arrestor available separately for those venturing into the woods
  • Proudly developed and made in the USA
