Bmw G 450 X
The Bmw G 450 X has a top speed of 160 km/h, produces 52 hp and weighs 118 kg. Motoryk rates it 6.5/10.
The BMW G 450 X was introduced in 2008 as BMW Motorrad's entry into the supermoto segment, representing the brand's first serious attempt at a lightweight, competition-oriented single-cylinder machine. Developed in collaboration with Austrian manufacturer KTM (sharing some engineering DNA), it featured a high-revving 450cc four-stroke engine with an innovative centrally-positioned mass concept, placing the engine high and forward in the frame for improved weight distribution. It was discontinued after a short production run ending around 2010, largely due to modest sales success despite its technical ingenuity.

What Buyers Should Know
Unique Counterbalanced Engine
The G 450 X uses a single-cylinder 450cc engine mounted unusually low and rearward in the frame, giving it a remarkably low center of gravity for a dirt bike. This improves handling but also means engine work can be more labor-intensive and costly than typical enduro bikes.
Watch the Clutch System
A known weak point is the hydraulic clutch and oil-bathed clutch system, which can develop leaks or wear faster than expected if maintenance intervals are ignored. Always verify service history and check for clutch slippage before buying used.
Low Production, Niche Resale
BMW produced the G 450 X only from 2008 to 2009, making it a relatively rare bike with a small parts and support network. Resale value is modest due to limited demand, but finding affordable used examples is possible — just ensure parts availability before committing.
Generations & Specs by Year
Only generation produced. Telelever front suspension, counterbalanced single-cylinder 450cc engine, supermoto styling. Discontinued after two years.
"Brilliant idea, half-finished execution, cult status earned anyway."
The G 450 X rides like nothing else BMW ever made — that counterbalanced single spins so smoothly you forget it's a thumper until you're deep in a corner and it reminds you with a sharp, urgent bark of power. The Telelever up front gives you genuinely weird but confidence-inspiring feedback on loose dirt and paved back roads alike, though the rear linkage geometry had owners chasing setup forever. I spent two seasons on one and loved it roughly 70% of the time; the other 30% I was bleeding the hydraulic clutch, sourcing an increasingly rare water pump impeller, or explaining to a dealer why they needed to actually read the service manual. BMW built a genuinely exotic, lightweight enduro-supermoto hybrid and then apparently decided parts availability was someone else's problem.

Used Buyer Review
"Rewarding but high-maintenance — buy cheap or walk away."
$3,500-$6,500 usedThe G 450 X was BMW's ambitious stab at the supermoto/enduro crossover market, and honestly it's a fascinating mess. The Husaberg-derived single makes a genuinely punchy 45 horsepower and the chassis is razor-sharp when it's working properly. On a good day, this thing carves canyons with serious intent and feels properly exotic. Problem is, finding a good day requires due diligence. Here's what you need to know before handing over cash: the counterbalanced single runs hot, the throttle body has a notorious flat spot around 4,000 rpm that BMW never fully resolved, and parts availability is genuinely painful. These weren't sold in massive numbers and BMW discontinued them quickly for good reason. Always check service history obsessively — neglected valve clearances will bite you hard. Budget an extra $500 minimum for a professional pre-purchase inspection. That said, a properly maintained example bought cheap enough is a genuinely rewarding machine. Just go in with eyes wide open and mechanical sympathy in abundance.
