Ray ZR

2017 Yamaha Ray ZR Technical Analysis & Specification Breakdown

Positioned in Yamaha's scooter motorcycle lineup, the 2017 Yamaha Ray ZR utilizes a 113 cc (6.9 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 7.2 HP (5.3 kW) at 7,500 rpm while maximum torque reaches 8.1 Nm (6 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 63.7 HP per liter and a 2,500 rpm working window between peak torque (5,000 rpm) and peak power (7,500 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 Ray ZR measures 105 kg (231 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (14.58 kg per horsepower). Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,270 mm (50 in) wheelbase engineered for quick, flickable steering geometry. The 5-liter (1.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
