I'm in the process of looking at a 2002 mz baghira 660, I know that they don't make them any more so I'm not sure how hard it will be to replace parts like the rear brake pad, seat cover, and damaged plastic. The bike also has about 17k km on it, the handle bars are very slightly bent and the start up is a little bit slow. What would you recommend as a good buying price? Also, do I need to get specific brake pads and valves?
