The kwacker rear was better than all the brakes on the mutley put together,and o quoted the wrong bike,it was the new Z1000SX
I bought a Z1000sx in 2013 two weeks before going to Scotland. Wife was on her monster 796. By the time I got to fort William I wanted to burn it and walk home. Vibes were a nightmare at 6000 ish rpm. Elbows wrists and knees all in agony. And my backside was dead. I had to ride side saddle all the way home. Rear brake light failed on it.I had it 3 months and px it for the multi. Best bike I've ever had. Not one problem and coming up to 15000 miles now. And the back brake works.
