What if BMW still produced their G450X enduro bike?
In 2008, BMW Motorrad unveiled a machine few expected: a hardcore, race-ready 450cc enduro designed to compete with the Japanese and European dirt machines. Although the design brief called for a machine that mirrored established design concepts in the 450 four-stroke class, BMW engineers couldn’t help themselves — the G450X incorporated a number of engineering innovations.
“BMW has never been a company to follow traditional concepts. At least not the traditional concepts of others! So even though this new 450cc machine is a dramatic departure from the company’s more usual touring fare, the engineers also didn’t play it safe by simply copying current dirtbike designs.” –Cycle World
These innovations included an underseat fuel tank, which centralized mass, and a coaxial swingarm pivot wherein the front sprocket shared the same axis as the swingarm pivot, thereby eliminating chain tension variation and reducing gearbox stress. What’s more, the engine was tilted 30 degrees forward and the crankshaft rotated backward to help load the front wheel and improve cornering traction.
The bike arrived in North America as a street-legal dual-sport, though it was a pure dirt bike beneath the lights. In road-legal trim, it weighed just 265 pounds dry and produced 40 hp…though this jumped to 50 ponies with a $250 pipe and “Power Plug” fuel map. The bike received high marks from various reviewers, particularly the engine, which was designed in Germany and produced by Kymco in Taiwan.
“It’s an incredible rock climber. Who would have guessed that a dual-sport bike would be so good at low-speed obstacles and extreme sections? The biggest advantage that the Beemer has is the motor. The power delivery is smooth and perfect off the bottom without a hint of the lurchiness that plagues so many fuel-injected bikes. It never stalls; it never flames out; it never coughs. The motor feels like it could be dropped into a trials bike.” –Dirt Bike
Alas, the BMW G450X only lasted until 2011, though the engine and frame would serve as the basis for several Husqvarna models.
This newly customized 2010 G450X comes from Argentina’s STG Tracker. One of their friends and clients has been riding the bike hard for years.
“The owner loves this bike, he uses and abuses it, so it was a little tear down, but in a good way! He wanted to fix all the scratches and broken things and make it look more ‘modern’ in the way, with a twist of that Baja style with the double front light.” -Marcelo Obarrio, STG Tracker
So the 16-year-old dirt horse got torn down for a modern rebirth. The most obvious element is the Baja-style dual-headlamp setup enclosed in a custom-made headlight cage. We’re big fans of this style, and it gives the bike an exotic desert racer look.
The Marzocchi fork and rear Öhlins rear shock were both refurbished, and the bike is now running an SC Project exhaust. Nearly every component that might show the bike’s age was powder-coated: hubs, rims, handlebars, risers, triple trees, etc. There’s shorter front fender, a seat reupholstered with anti-slip material, new handguards, a custom stainless steel sidestand fabricated in-house, and LED lighting and indicators.
Of course, the new paintwork is another standout element of the build, laid down by Taller Minissale. The new livery, combined with the powder-coated parts and modern lighting, makes this G450X look like a 2026 model that just rolled out of a BMW Motorrad showroom. Bravo to Marcelo and the STG Tracker team!
