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.
La BMW G 450 X a été introduite en 2008 à l'occasion de l'entrée de BMW Motorrad dans le segment des supermotos. Il s'agissait de la première tentative sérieuse de la marque en matière de monocylindre léger et orienté vers la compétition. Développé en collaboration avec le constructeur autrichien KTM (qui partage un certain ADN d'ingénierie), il était équipé d'un moteur quatre temps de 450 cm3 à haut régime avec un concept de masse innovant en position centrale, plaçant le moteur en haut et en avant dans le châssis pour une meilleure répartition du poids. Il a été abandonné après un court cycle de production qui s'est terminé vers 2010, en grande partie en raison d'un succès commercial modeste malgré son ingéniosité technique.

Ce que les acheteurs doivent savoir
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.

"Idée géniale, exécution à moitié terminée, statut de secte mérité quand même."
La G 450 X se conduit comme aucune autre BMW n'a jamais conçue : ce single spin contrebalancé est si fluide que vous oubliez que vous êtes au plus profond d'un virage et qu'il vous rappelle avec un aboiement de puissance aigu et urgent. Le Telelever à l'avant vous donne des informations vraiment étranges mais inspirantes sur la terre meuble comme sur les routes secondaires pavées, même si la géométrie de la tringlerie arrière a incité les propriétaires à rechercher la configuration depuis toujours. J'ai passé deux saisons sur l'une d'entre elles et je l'ai adorée environ 70 % du temps ; les 30 % restants, j'étais en train de purger l'embrayage hydraulique, de me procurer une turbine de pompe à eau de plus en plus rare ou d'expliquer à un revendeur pourquoi il avait besoin de lire le manuel d'entretien. BMW a construit un hybride enduro et supermoto léger et véritablement exotique, puis a apparemment décidé que la disponibilité des pièces était le problème de quelqu'un d'autre.

Évaluation d'un acheteur d'occasion
"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.
