CRF250R\'11-12 - Yoshimura RS-4 Ti/Ti Full System
Yoshimura engineers developed the CRF250R exhaust using experience gained developing the system for our CRF450R exhaust and it works brilliantly.

Yoshimura has been the official exhaust supplier to Team Honda Red Bull Racing for several years now and we have adapted that knowledge to the new CRF250R. Since the CRF250R shares many features and parts as it's big brother, it was an obvious choice which system to provide. 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 small Honda's power delivery was also realized.

The RS-4 is pentagonal shaped muffler that features a carbon fiber cone end cap, two staged stepped baffle and striking good looks. The RS-4 muffler features a new front cap design that functions as a poly-resonant chamber. This design makes for a quieter muffler with improved mid to top end power.

This Full System includes Titanium header and tail pipe, titanium sleeved RS-4 muffler, installation hardware, and detail step-by-step instructions.

Titanium Systems come with a AMA Pro Racing sound insert installed in the muffler.
