Attention thundercat owners

Recommended Posts

Just read in a magazine there's a possible problem with the gearbox sprocket nut on all thundercat 600 fazer some early R6 and FZ6 models. Apparently the sprocket retaining nut can come loose and do some serious damage to the gearbox output shaft. Yamaha have released a deeper nut with a bit more thread that cures the problem. Part number 90891-101124
