Built around Wakan's naked motorcycle platform, the 2010 Wakan 100 Roadster features a 1640 cc (100.1 cu in) air-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 120 HP (87.6 kW) at 5,750 rpm while maximum torque reaches 165 Nm (121.7 lb-ft) at 4,250 rpm, transferring power to the rear wheel through a 5-speed gearbox and belt final drive. With a specific output of 73.2 HP per liter and a 1,500 rpm working window between peak torque (4,250 rpm) and peak power (5,750 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the 100 Roadster measures 201 kg (443 lbs) wet (curb), translating to a power-to-weight ratio of 0.6 HP/kg (1.68 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,380 mm (54.3 in) wheelbase engineered for quick, flickable steering geometry. The 13-liter (3.4 US gal) fuel tank paired with a rated consumption of 5.8 L/100 km provides an estimated theoretical range of roughly 224 km (139 miles) between fill-ups, while factory top speed is listed at 248 km/h (154 mph).

Torque
Torque is useful for judging real-world pull, especially for touring, commuting and loaded riding.
Seat Height
Check the seat height against your inseam and riding posture before choosing a motorcycle.
Weight
Compare weight carefully because it affects low-speed handling, parking and confidence.
Fuel Capacity
Fuel capacity helps estimate touring range and how often you may need to stop.
Brakes
Brake setup is worth comparing if you ride in traffic, mountains or with a passenger.
Suspension
Suspension details can matter for comfort, road feel and long-distance riding.
Transmission
Transmission and final drive affect maintenance, smoothness and everyday usability.
