Technical Overview
2017 Yamaha XSR900 Yard Built Monkeebeast by Wrenchmonkees Technical Analysis & Specification Breakdown
At the heart of the 2017 Yamaha XSR900 Yard Built Monkeebeast by Wrenchmonkees allround motorcycle, Yamaha features a 847 cc (51.7 cu in) liquid-cooled in-line three, four-stroke configuration. In factory specification, peak output is rated at 115 HP (83.9 kW) at 10,000 rpm while maximum torque reaches 87.5 Nm (64.5 lb-ft) at 8,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 135.8 HP per liter and a 1,500 rpm working window between peak torque (8,500 rpm) and peak power (10,000 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
Rider ergonomics and chassis geometry center around a 830 mm (32.7 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams. The 14-liter (3.7 US gal) fuel tank paired with a rated consumption of 5.2 L/100 km provides an estimated theoretical range of roughly 269 km (167 miles) between fill-ups.
