The Royal Star is a massive, retro-styled touring cruiser powered by a larger, detuned version of the 1198cc V-Max engine. The V-4 engine, which makes 104kW (140bhp) in the V-Max, produces around half that figure in the Royal Star. Yamaha has altered the engine's carburation and timing to move the power further down the rev range: the peak torque figure of 82ft lb is produced at just 3500rpm. Having said that, the Royal Star is incredibly heavy, at 328kg (7231b), limiting its dynamic appeal. Beefy fork shrouds, extensive chrome-plating and spoked wheels are all authentic cruiser-style. Its touring abilities are further helped by the low-maintenance shaft drive and 18-litre (4 gal) fuel tank.
