Product Description

Yoshimura has been the official exhaust supplier to Team Honda Red Bull Racing for several years now. All of that experience has helped Yoshimura in making an exhaust that compliments an already great bike. The RS-4 not only increases power and is light, but it also has a lower centralized mass coefficient to provide better handling. Additionally, an overall improvement to the big Honda's power delivery was also realized.

Yoshimura only offered the RS4 Slip on for the 2013 KTM350 EXC-F and not a full system. Unfortunately do not have a listing available yet for the 2014 model.

Yes, this RS-4 definitely works with the 2013 Kawasaki KX250f. When adding to your cart please make sure to profile the correct model information.
