The BMW G 650 XMOTO (Internal Code 0167) represents a pivotal moment in BMW Motorrad history. Launched as part of the ‘G’ series trio, it was engineered to shed the brand’s conservative image. A unique engineering highlight of this model is its dry-sump lubrication system, which utilizes the motorcycle’s frame as an oil reservoir. This design choice allowed for a significantly higher ground clearance and a slimmer engine profile, optimizing the bike’s center of gravity for aggressive supermoto handling.
Engineering Overview
At the heart of the XMOTO is the legendary Rotax-derived 652cc single-cylinder engine. Unlike its predecessors, the G-series version featured a lightened crankshaft and a more powerful alternator. The 0167 variant specifically caters to the street-tarmac enthusiast, featuring 17-inch cast aluminum wheels and a massive 320mm front brake disc gripped by a Brembo four-piston caliper.
Maintenance Essentials
Lubrication System
For optimal performance and gearbox longevity, MotoSpecsLab recommends SAE 15W-50 oil. It must meet API SJ and JASO MA2 standards to ensure the wet clutch operates without slipping. The total capacity is 2.3 liters. Due to the dry-sump design, checking the oil level requires the engine to be at full operating temperature and held upright.
Ignition and Electrical
The engine utilizes a high-efficiency combustion cycle that relies on the NGK DR8EB spark plug. For electrical reliability, especially given the high-compression start-up requirements of a large single, the YTZ10S battery is the factory-specified unit. Owners should ensure terminal connections are vibration-resistant, as single-cylinder harmonics can loosen standard fittings.
Chassis and Tires
The XMOTO’s agility is highly dependent on tire profile and pressure. The standard fitment is 120/70 ZR 17 for the front and 160/60 ZR 17 for the rear.
- Front Pressure: 2.2 bar (32 psi)
- Rear Pressure (Solo): 2.4 bar (35 psi)
- Rear Pressure (Passenger): 2.5 bar (36 psi)
Maintaining these pressures is critical to preventing ‘cupping’ on the front tire and ensuring stable turn-in characteristics.
Editor’s Verdict
The BMW G 650 XMOTO remains a cult classic. While its production run was short (2006-2009), its build quality exceeds typical supermoto standards of that era. For the modern collector or rider, adhering to the 0167-specific maintenance schedule is the key to preserving the high-revving nature of this unique German-Austrian collaboration.
