Description
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.
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.
