Yoshimura Motorcycle Exhaust
A host of R-55, R-77 and R-77D applications are no available to outfit the 2011 Honda CB1000R, Yoshimura announced Monday. Slip-ons will be available in a number of configurations.
The R-55 is one of Yoshimura’s most popular pipes, and for good reason. It’s a hybrid of Moto-GP, Superbike, and Yoshimura style, which makes for a pretty impressive package. The R-55 features an asymmetrical shape with a straight baffle and a removable low volume insert.
The pipe is TIG-welded to Yoshimura quality standards and is made of high-quality polished stainless steel with the option of a polished stainless steel or carbon fiber end cap. The laser-cut mounting bracket is TIG-welded to ensure strength and good looks. You can get the R-55 as a slip-on muffler, which attaches simply to the stock exhaust mounting slip-fit.
The R-77 is serious business when it comes to performance as it was designed with racetrack feedback from racers Tommy Hayden and Blake Young. The R-77′s trapezoidal shape allows a large volume of packing material and in turn delivers top performance.
With a straight baffle and removable low-volume insert, the R-77 muffler’s front cap is MIG-welded, while the Carbon Fiber end cap is riveted using high-end 304-L polished stainless steel rivets and bands. You can get the muffler in stainless steel, titanium, or race-inspired carbon fiber.
The R-77 comes as a slip-on muffler, which attaches simply onto the stock exhaust mounting slip-fit, or on various full Yoshimura exhaust systems. The cone end caps come in either polished stainless steel or carbon fiber and the slip-on itself is mounted with a stainless steel mounting clamp.
The R-77D is a dual-outlet version of the race-proven R-77. The R-77D boasts a carbon fiber cone end cap and requires no inserts or restrictions, increasing muffler packing life, and provides 5% more open exhaust outlet area and as much as 3 decibels lower sound output (compared to open standard R77). The R-77D also offers greater gains in bottom and mid range power with out restrictive inserts.
