About the 1998 Yamaha VMAX

The Yamaha VMX1200 V-Max has a beautiful, almost liquid power delivery from just above tickover, with a crazed step up in poke from about 4000rpm as the V-Boost fuel charge system kicks in. The Yamaha VMX1200 V-Max motor puts a grin on the face of the most jaded speedfreak. It punches you in the guts with its sheer torque.

You can turbocharge the motor, add nitrous, almost anything really and the V-4 lump will take it. The Yamaha VMX1200 V-Max’s chassis is the weaker half of the motorcycle by far and as it was designed to race the strips of California, the V-Max can suffer if ridden too often in British rain.
