Technical Overview
2007 Keeway X-Ray e Technical Analysis & Specification Breakdown
Built around Keeway's cross - motocross motorcycle platform, the 2007 Keeway X-Ray e features a 49.6 cc (3 cu in) liquid-cooled single cylinder, two-stroke configuration. In factory specification, peak output is rated at 6.3 HP (4.6 kW) at 8,500 rpm while maximum torque reaches 5.6 Nm (4.1 lb-ft) at 7,000 rpm. Internal engine geometry specifies a bore and stroke of 40.3 x 0.0 mm (1.6 x inches) with a 7.0:1 compression ratio.
On the scales, the X-Ray e measures 150 kg (331 lbs) wet (curb), translating to a power-to-weight ratio of 0.04 HP/kg (23.81 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,380 mm (54.3 in) wheelbase engineered for quick, flickable steering geometry. The 10-liter (2.6 US gal) fuel tank paired with a rated consumption of 2.5 L/100 km provides an estimated theoretical range of roughly 400 km (249 miles) between fill-ups, while factory top speed is listed at 45 km/h (28 mph).

Use this page to compare this motorcycle by its real specifications, not only by model name. Focus on the details that affect fit, comfort, handling, range and ownership.
Power
Compare engine output with similar motorcycles if acceleration, highway use or two-up riding matters.
Torque
Torque is useful for judging real-world pull, especially for touring, commuting and loaded riding.
Weight
Compare weight carefully because it affects low-speed handling, parking and confidence.
Fuel Capacity
Fuel capacity helps estimate touring range and how often you may need to stop.
Brakes
Brake setup is worth comparing if you ride in traffic, mountains or with a passenger.
