Description

The KTM RC390 and 390 Duke are entry level bikes that can quickly be transformed into potent race bikes/track day machines. Yoshimura has pumped up the looks and performance on these small, yet fun bikes with our Race Series 3/4 systems in stainless/carbon Mini R-77 muffler options.

When heading to the race track, everything counts, with either muffler option you lose half the weight of the stock system and gain 2.5% max H.P. and 3.3% max ft. lbs. of torque. Styling and sound are all Yoshimura with our classic R-77 profile muffler. We've made the performance, now its time for you to realize the power!

Proudly made in the USA.

Attention international customers: This product was designed and tested to be compatible with vehicles in the U.S. marketplace only. Compatibility, including fitment and performance, may vary by marketplace.

  • Uniform heat coloration
  • Increased fatigue strength
