Yoshimura RS-12 Exhaust System Kawasaki KX250

Enhance your Kawasaki KX250F with Yoshimura's RS-12 Signature Series full system exhaust, designed specifically for the latest model. This state-of-the-art system adds up to 3.3% more horsepower at 11,000 rpm and 3.4% more torque at 10,600 rpm, giving the 2025 KX250F an unmistakable edge on the track. Crafted to complement the new bike's chassis and engine, the RS-12 maximizes performance throughout the power spectrum, offering improved top-end power and more engaging performance where it counts.

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
