The Yamaha V-Max is a motorcycle manufactured by Yamaha, which is known for its powerful V4 engine, shaft drive, and distinctive styling. While famed for its quick acceleration, it is often criticized for its poor cornering ability and soft suspension. Instead of the V-Boost on the original carburated V-Max, the fuel injected VMAX uses YCC-I and YCC-T. Yamaha Chip Controlled Intake (YCC-I) is a new addition to the VMAX. The airhorns inside the airbox are lifted by a servo activated at 6650 RpM to open up the airway underneath. This shortens the length of the intake system from 150mm to 52mm. This system had it's first appearance in the Yamaha stable with the 2006 YZF-R1. The MV Agusta F4 Tamburini was the first bike with such a system. Massimo Tamburini invented this idea. It is called Torque Shift System (TSS) on the Agustas.
