2009 Yamaha V Star® 950, 2009 Yamaha V Star® 950 Key Features:

As a new benchmark in entry cruiser class, the V Star 950 brings it all together in an exciting new package.

The new 942cc 60° V-twin engine is both simple and sophisticated. Traditional air cooling is used, but this engine also has four-valve cylinder heads, ceramic-composite-lined cylinders, forged aluminum pistons, and fuel injection for spirited performance. A straightforward SOHC design is used, with special compact roller- type rocker arms, helps to keep the top end lighter for more mass centralization.

There’s more going on in the newly designed double-cradle steel frame than its decidedly clean, simple appearance. The steel main frame, which uses the engine as a stressed member of the chassis, has been carefully designed to offer an ideal rigidity balance in the longitudinal, lateral, and torsional directions.

The V Star 950 brings styling to a sleek new level, one we call ”Sport Classic.” There are many “classic” cruiser styling characteristics. However, what’s unique is the V Star 950’s light and sporty look characterized by the large diameter front & rear wheels with low profile tires, thin body shape, and fenders that have just the right amount of volume and draw.

Features & Benefits

The 942cc (57.5 cu. in) engine is an air-cooled SOHC 60° V twin. With four valves per head, a pent-roof shaped combustion chamber, and 9.0:1 compression ratio, this engine has been carefully designed to produce excellent power characteristics and best-in-class acceleration.

To keep friction loss to a minimum and help the engine achieve the ideal performance characteristics, special compact roller-type rocker arms with needle bearings are used.

The combustion chamber shape was precisely engineered to direct the fuel air charge into the center of the piston for faster combustion and maximum power. Ceramic-composite-plated cylinders provide excellent heat dissipation and reduced oil consumption.

High-quality forged aluminum pistons have a lightweight, high- strength compact design that contributes to reduce vibration.

The designers realized that engine’s V twin character was so pleasing on its own that a counterbalancer was unnecessary. This also contributes to simplicity and less operating noise.

Sophisticated fuel injection is used on the V Star 950. The injectors are 4-hole, two-directional types with spray aimed at the valve surfaces. That produces good fuel atomization for faster and more complete combustion which contributes to excellent drivability. The fuel injection system also adopts an ISC (Idling Speed Control) valve for outstanding idling stability.

Lubrication is provided by a simple, reliable wet sump system
