Chino, Calif – As official supplier to the Honda Red Bull factory Motocross/Supercross team, Yoshimura knows something about how to get the most power out of the newly designed '09 CRF450R from Honda. One easy, inexpensive and effective way is to replace the stock header with a Yoshimura brand – which, until now, was not available without purchasing a RS-4 Full System.
Yoshimura has just announced that CRF450R replacement headers are now available that will fit either the Honda stock muffler or a Yoshimura RS-4 exhaust. These mandrel bent headers have larger diameter tubing for smoother power delivery and are available in either stainless steel or titanium.
Stainless Steel Replacement Header:
Part Number: 2257-101-K
Titanium Replacement Header:
Part Number: 2257-704F-K
Available now at local dealers everywhere.
