In 1992 Yamaha introduced the VMax-4, VX750S. It was powered by a 743cc liquid-cooled in-line 4 cylinder engine with a Counter-Point PTO shaft driven from the center of the engine, increasing efficiency and reliability and strength. The cylinder combustion occurred every 90 degrees of crankshaft rotation for a smooth operation.
This new machine was a monster with power. It was built on a lightweight aluminum frame with Telescoping Strut Suspension (TSS) and adjustable Pro-Action rear suspension which delivered a comfortable ride. It also had aluminum skis with plastic shoes. The Vmax-4 would never be copied.
