In 1975 Yamaha really started the suspension revolution in motocross with their amazing monoshock bikes.  It was an unusual year in that the big YZ360 monoshock continued in limited production, and the all-new MX400B monoshock was introduced.  Though designed to be a race bike for novice and intermediate riders, almost all riders felt the 400 was easier to ride and faster around the typical motocross track than the exotic and peaky YZ360.  This immaculate first year monoshocker can be raced or shown.  Fresh restoration with stainless Buchanan spokes, new rims, Dunlop tires, all re-plated hardware, HPI ignition, custom pegs, fresh top end (1 race).  Much more.  Unbeatable to the first turn!  Comes with the tank shown - an original paint, undented beauty, and a very presentable, if sporting a few dents, "race tank".
