Description

Introducing the RS-4 Exhaust Systems for the 2010 Honda CRF250R with fuel injection. Our 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.

An AMA-approved sound insert comes installed in the muffler.

We were a little disappointed when the injected 2010 Honda hit the land of Oz. Compared to the carbi 2009 the engine lacked response right through the whole range. What Honda do not tell you is that they can be readily mapped and modified. Thats where Yoshi came on the scene. We know they were good, cause we ran one a year or so ago on the CRF150R and it made a huge difference. Fitting the RS-4 system, re-mapped makes the 2010 and now the 2011 a rocket from the gates. Can not wait to see what other goodies Mr Yoshimura has in stall for us. If you want the hole shot and to run up front - go Yoshimura. Do the research and dont waste your time on those other brands, cause Wantanabe son is already ahead of the rest.
