In 1983 Suzuki introduced the box-section aluminium frame to the world on the Suzuki RG250. In Japan this type of frame was an instant hit. In 1984 The Dutch frame builder Nico Bakker received a rather suprising phone call from a Japanese motorcycle dealer if he could make such a frame for the Yamaha RZ250. They made a deal for 50 frames, Nico used a brand new RD350YPVS as a reference point. The alloy frame became 6.5 kilo lighter than the original steel frame, it had all the mounting points for the original bodywork. Two of the frames stayed in the Netherlands, one of these is the yellow bike in the photo set. It was equipped with a lot of special parts like an alloy tank, PVM wheels, WiWo brakes and a White Power shock. How many of these bikes still exist in Japan? The 2 Dutch bikes survived.
