Technical Overview
2008 Hartford VR 125 Z Technical Analysis & Specification Breakdown
At the heart of the 2008 Hartford VR 125 Z sport motorcycle, Hartford utilizes a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 11 HP (8 kW) at 9,000 rpm while maximum torque reaches 8.7 Nm (6.4 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 88.7 HP per liter and a 1,000 rpm working window between peak torque (8,000 rpm) and peak power (9,000 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 VR 125 Z measures 122 kg (269 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.09 kg per horsepower). Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,375 mm (54.1 in) wheelbase engineered for quick, flickable steering geometry. The 12-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
