Crux

2025 Yamaha Crux Technical Analysis & Specification Breakdown

Built around Yamaha's allround motorcycle platform, the 2025 Yamaha Crux pairs a 106 cc (6.5 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 10.2 HP (7.4 kW) at 7,500 rpm while maximum torque reaches 7.5 Nm (5.5 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 96.2 HP per liter and a 1,500 rpm working window between peak torque (6,000 rpm) and peak power (7,500 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

On the scales, the Crux measures 113 kg (249 lbs) wet (curb), translating to a power-to-weight ratio of 0.09 HP/kg (11.08 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,260 mm (49.6 in) wheelbase engineered for quick, flickable steering geometry. The 11-liter (2.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
