Yamaha VMAX

What better a representative of the power cruisers category of production bikes than this- the Yamaha VMAX. Built for the drag strip, it 1679 cc( 102 cu in) V4 engine. With its massive engine and brawny looks, it is the current benchmark of the category that its predecessor created, which in itself was a cult bike. With a power figure upwards of 200 ps and about 150 nm tarmac shredding of torque, it blows all competition off the drag strip. Even with all-powerful beasts like the cool Harley Davidson VSRC series and the XXL sized Triumph Rocket III vying at the top honors, it still hails as the current champion in this category.

In 2005, at the 39th Tokyo Motor Show, Yamaha displayed this all-new V-Max concept bike. It featured a new chassis, upgraded components all around, and state-of-the-art braking components.

Handling wise, this is now Yamaha R1 or BMW S1000RR, but it handles rather well around bends- with the help of greatly centralized mass. The long wheelbase might seem to be a bad thing around corners, but it isn't. Moreover, the long wheel base provides it with great stability in a straight line, something it was actually mend to devour(read: drag strips).

On 4 June 2008, Yamaha officially released a completely redesigned 2009 VMAX in North America and Europe. The features of the VMAX include an all aluminium frame with its 1,679 cc (102 cu in) liquid cooled V4 DOHC engine used as a stressed member of the chassis, an electroluminescent instrument readout, Yamaha Chip Controlled Intake (YCC-I), fully adjustable suspension, anti-lock brakes, slipper clutch, a fuel tank beneath the seat, and a distinctive key.

On 20 September 2009, VMAX was also launched in India.

YCC-I/YCC-T

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 6,650 rpm to open up the airway underneath. This shortens the length of the intake system from 150 mm to 52 mm. This system had its 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.

Yamaha Chip Controlled Throttle (YCC-T) is also a new addition. The throttle cables are connected to a throttle position sensor and a new computer called G.E.N.I.C.H. that operates the butterfly valves, the EXUP valve in the exhaust and the other components involved, such as the igniter unit, and the YCC-I lifter unit. The YCC-T computes all the input of the sensors and calculates the best throttle position, ignition advance, EXUP valve and injection time in milliseconds.
