2009 G 650 X Challenge - Pros & Cons

Strengths

Fuel injection: The fuel injection system delivers crisp throttle response and reliable cold starts regardless of altitude or temperature.

Considerations

Tall seat height: The 930 mm seat height will challenge shorter riders - tiptoeing at low speeds is something to factor into your decision.
Modest fuel capacity: The 9.50-litre tank means more frequent fuel stops on longer rides, which is worth planning around on touring routes.
Chain final drive upkeep: Chain final drive needs regular cleaning, lubrication and tension checks to get full life out of the sprockets.

Wear Points & Servicing Notes

Fuelling & injector care

Fuelling comes from fuel injection. Systems like this are largely maintenance-free beyond keeping fuel quality decent and injectors clear - a fuel-system cleaner every service interval is cheap insurance.

Brake disc and pad wear

The Single disc. Optional ABS front brake gives strong, progressive stopping power. Disc thickness and pad depth are worth checking at every tyre change, since worn pads can score the disc surface.

Suspension condition on used examples

Up front, the G 650 X Challenge runs Upside-down front fork, Ø 45 mm, rebound and compression damping adjustable and Cast aluminium dual swing arm, Air Damping System, spring pre-load and damping continuously variable by air pressure at the rear. On a used example, check fork seals for weeping oil and test the rear linkage for play - seals are a relatively cheap fix but useful when negotiating price.

Final drive maintenance

Final drive is by chain - expect to clean and lube it every few hundred kilometres and check tension regularly; a neglected chain wears the sprockets faster than the chain itself.

Frame & chassis check

The frame is Bridge-type steel section frame with bolted-on cast aluminium side elements, bolted-on aluminium rear section - worth a visual check for corrosion or impact damage around the head-stock and swingarm pivot on any used example, since frame damage is far costlier to fix than any service item.

G 650 X Challenge - Buying & Maintenance Guide

What to check before buying

When inspecting a used 2009 BMW G 650 X Challenge, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained G 650 X Challenge should fire up cleanly and settle to a smooth idle within a few seconds.

Oil and filter changes

Regular oil changes are the single most important maintenance task on any G 650 X Challenge. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. Always use the correct viscosity grade as specified in the owner's manual.

Fuel system care

The G 650 X Challenge's fuel injection system is durable but benefits from quality fuel and the occasional use of a fuel-system cleaner additive. If the bike has been stored for more than three months, drain and replace the fuel to prevent varnish deposits in the injectors.
