The Yamaha
V Star 1,300cc is now middleweight
territory). The new bike had to have more power with “Big Cruiser sensual
character,” so in response Yamaha decided to hide the upgrades, making them
visible only to the trained eye.For starters the V Star 1300 Tourer is
now fuel injected, with dual 40mm throttle bodies feeding an all-new engine
with four valves per cylinder.
The big change is that the new bike is liquid-cooled, making it the first such Yamaha cruiser in a decade. To keep the traditional look of an air-cooled engine, the 1300 uses internal coolant passages with brushed exterior cooling fins for a clean, traditional cruiser engine look. The radiator is cleverly positioned between the frame spars, with the inlets and outlets neatly tucked above and below the engine-out of sight to the casual observer. Bore and stroke are increased to 100mm x 83mm from the 1100′s 95mm x 75mm, and the compression ratio has also been raised to 9.5:1 from its predecessor’s 8.3:1.
