The Booster appeared in 1989, As you know, Yamaha having bought the Motobécane brand in 1983 renamed MBK, the scooter models are distributed under both brands, in this case the booster for MBK and the BW’s to Yamaha. Attention it must be pronounced, we say biwize! Designed forar the Japanese firm for the Japanese, it’s a real flop there.

It is the French factory of Saint Quentin that will take again the manufacture, then betting on the European and French market in priority to make known the model. The success is immediate and allows to reach important production rates to reach 26 000 sales in 1993!
This success will be confirmed for a decade. MBK has certainly found here the replacement (or the cannibal?) Of his mythical moped, which she will begin to run out of sales in the late 90.
