Street Style: A custom BMW G310R from Buenos Aires

To describe Argentina’s capital city of Buenos Aires as busy is an understatement. The 78-square-mile city has a population of over three million people, with over 15 million occupying the greater metro. As you might expect, motorcycles can be a fun way to get around such populous areas—especially smaller-displacement, highly agile bikes that can slice through crowded city streets.

That’s exactly what we’re looking at today; a custom BMW G310R street tracker made to commute on, from the team at STG Tracker in Buenos Aires.

Manufactured by TVS in India for BMW, the G310R is the smallest bike in the German marque’s arsenal. Its single-cylinder mill puts out 33.6 hp and 28 Nm—plenty for inner city jaunts. The stock bike borrows its styling from BMW’s bigger naked bikes, but this one’s been radically transformed by STG.

Although the donor bike only had 500 km [310 miles] on the clock, it wasn’t a completely blank canvas. Another workshop had started work on it already, but the client had paused the project and brought it to STG instead.

The previous crew had made the custom carbon fiber tank cover and tail section. But while the client was happy with the general design, nothing was fitting as it should. Shop boss Marcelo Obarrio kicked things off by building a new fuel tank to sit under the cover, then fabricating new mounting tabs on the frame to mount everything.

The standard BMW bodywork is angular and sporty—but the custom cover softens those hard lines, while retaining just the right amount of edginess. Finished with a few choice parts from Driven Racing in the USA, it’s certainly fit for purpose.

Marcelo turned his attention to the rear end next. The pre-existing tail unit was massaged into place, with a new subframe fabricated to accommodate it. Capping it off is a new Alcantara seat cover, with a hexagonal stitching pattern that matches the inlet grills at the front of the tank.

Hidden beneath the seat is a Motogadget controller, while the battery now lives under the swingarm. The imperceptibly small turn signals are also from Motogadget, while the taillight has been integrated into the rear end for a slick, factory look.

The stacked headlights are bolted to custom-CNC’d aluminum brackets, with STG choosing to reuse the stock dashboard. We’re getting a slight insectoid vibe from the front end—especially with the subtle honeycomb pattern on the tank cover.

The original front fender was reshaped into what you see here, but the upper fork yoke is custom. A set of carbon fiber bars from Driven Racing are bolted onto taller risers, to get the riding position as upright as possible. They’re capped with Motogadget grips, mirrors and switchgear.

One of the G310R’s most notable features is its ‘backwards’ cylinder head; the intake port is ingeniously placed behind the radiator with the exhaust port at the back. BMW claims that this moves some of the weight rearwards for improved agility, which, if true, is perfect for a street tracker.

To make this party piece more obvious and to improve performance, STG fitted a custom-built stainless steel exhaust. It pops nicely against the blacked-out engine and rear shock, and probably sounds great.

To give the client more confidence over sketchy terrain (and to complete the tracker look), a pair of Continental TKC70 tires were fitted. A carbon fibre sprocket cover and adjustable rear-sets from Driven Racing USA round out the parts list.

The eye-catching paint was designed and laid down by the talented Ale Minissale. “He had total freedom on the design, which was inspired by BMW track cars, and he nailed it.” says Marcelo. “You either love it or you hate it!”

We love bold takes on new bikes, and STG Tracker has delivered in spades. Whether you’re a fan or not, using this bike to rip around the busy streets of Buenos Aires would be crazy fun—and that’s what motorcycles are all about.
