Technical Overview
2008 Yamaha Jog RR Moto GP Technical Analysis & Specification Breakdown
Built around Yamaha's scooter motorcycle platform, the 2008 Yamaha Jog RR Moto GP features a 49 cc (3 cu in) liquid-cooled single cylinder, two-stroke configuration. In factory specification, peak output is rated at 2.8 HP (2.1 kW) at 7,500 rpm while maximum torque reaches 3 Nm (2.2 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. Internal engine geometry specifies a bore and stroke of 40.0 x 39.2 mm (1.6 x 1.5 inches) with a 11.4:1 compression ratio.
On the scales, the Jog RR Moto GP measures 79 kg (174 lbs) dry. Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,210 mm (47.6 in) wheelbase engineered for quick, flickable steering geometry. The 5.5-liter (1.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
