Built around Wakan's naked motorcycle platform, the 2007 Wakan Road 1640 pairs a 1640 cc (100.1 cu in) v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 115 HP (83.9 kW) at 6,250 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 chain final drive. With a specific output of 70.1 HP per liter and a 2,000 rpm working window between peak torque (4,250 rpm) and peak power (6,250 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 Road 1640 measures 177 kg (390 lbs) dry, translating to a power-to-weight ratio of 0.65 HP/kg (1.54 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 1,370 mm (53.9 in) wheelbase engineered for quick, flickable steering geometry. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
