Positioned in Yamaha's custom - cruiser motorcycle lineup, the 2005 Yamaha Road Star Warrior 1700 relies on a 1670 cc (101.9 cu in) air-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 83.1 HP (60.7 kW) at 4,400 rpm while maximum torque reaches 135 Nm (99.6 lb-ft) at 3,750 rpm, transferring power to the rear wheel through a 5-speed gearbox and belt final drive. With a specific output of 49.8 HP per liter and a 650 rpm working window between peak torque (3,750 rpm) and peak power (4,400 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Road Star Warrior 1700 measures 298.4 kg (658 lbs) wet (curb), translating to a power-to-weight ratio of 0.28 HP/kg (3.59 kg per horsepower). Rider ergonomics and chassis geometry center around a 714 mm (28.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,669 mm (65.7 in) wheelbase engineered for planted straight-line stability. The 15.14-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
