More power and less weight for Kawasaki’s supersports superbike.
The 2011 ZX-10R features class-leading performance and electronics, and Yoshimura have announced the release of an R77 Performance End-Can developed specifically for Kawasaki’s flagship sports bike, which boosts power in open form and offers considerable weight savings over stock.
The R-77 End-Can uses a trapezoidal-shaped sleeve, maximizing muffler volume, while offering a sharp silhouette. There are two options to choose from; the R77 End-Can alone, that bolts straight onto the stock exhaust system, or the R77 End-Can with ¾ link pipe, which dispenses with the catalyzer. Both are designed and approved for circuit use only.
Tech Specs are as follows; weight of the stock can is 6.53kg.
