Custom Suzuki GN250 Bobber Looks Seriously Adorable, Flaunts Hardtail Frame

Despite what their workshop’s name might suggest, Marcelo Obarrio and Germán Karp have tackled an array of other styles aside from trackers over the years. Founder Marcelo was heavily involved in the BMX community prior to establishing STG, and he'd been building freestyle bicycles since the age of 23. Around a decade later, he took things up a notch and dove head-first into the motorcycling world.

His first professional build was a Suzuki GN250 completed back in 2013, before Germán joined STG Tracker to lend a helping hand. Now, the specimen we’re about to look at is also based on a GN250, more specifically a 1994 variant from Suzuki’s lineup. The machine was far from stock upon arrival at STG’s headquarters, though, as it had previously been converted into a street tracker (funny enough).

Although the owner didn’t want to let go of the trusty Japanese thumper, he did feel the need for something fresh in his stable. Marcelo pitched the idea of a stripped-down GN250 bobber, and this proposition immediately caught the client’s attention. For the most part, the STG duo was given free reign over the modifications, so they took the tiny commuter apart and began formulating a plan of action.

It was decided that a hardtail frame would be one of the project’s definitive traits right from the get-go. With this goal in mind, the guys kept the main part of the original framework, but they deleted the rear suspension, swingarm, and subframe in favor of a rigid setup. As the donor’s factory forks were way too long for the desired posture, Marcelo and Germán had them swapped with the shorter and slightly beefier units of a Honda CBX250.

These are held in place via custom triple clamps, with the lower one featuring integrated LED turn signals. Down in the unsprung sector, you will now find a pair of chromed aftermarket rims measuring 19 inches at the front and 16 inches on the opposite end. The front hoop is laced to a vintage hub taken from the workshop’s parts bin, and it makes use of a modified braking system.

STG decided to retain the standard drum brake at six o’clock, but they installed fresh shoes and adapted it to suit the frame’s hardtail construction. In terms of rubber, we find a retro-looking Imperial tire up north and Dunlop’s D404 compound down south. With the motorcycle’s running gear taken care of, it came time for Marcelo and his teammate to get started on the fabrication work.

First things first, they came up with a bespoke chain guard, which supports the license plate bracket and an LED taillight. You will notice a peanut-style gas tank sitting center-stage, built in-house using steel and topped with a CNC-machined aluminum filler cap. Right behind this custom fuel chamber lies a sprung saddle upholstered in black leather, but what you see beneath it isn’t actually an oil tank.

Appearances, as they so often say, can be deceiving, and the aforementioned item is an excellent case in point. Instead of motor oil, it houses all of the GN250’s electrical goodies, stashing them well out of sight for a clean look. STG Tracker fitted a handmade rear fender a bit further back, it being the only other bodywork component present on this stylish bobber. The custom wizardry continues at twelve o’clock, as well.

It does so in the form of a vintage-style headlight, which lives inside a chrome-plated housing and is supported by tailor-made brackets. There’s a groovy BMX vibe up in the cockpit area, where the Argentine specialists added a new handlebar manufactured from scratch. It’s adorned with Biltwell grips and inconspicuous switches, but you won’t be finding any instrumentation on this machine.

The GN250’s single-cylinder engine was freshened up internally, then it received a replacement carb that breathes through an aftermarket pod filter. At the other end of the combustion cycle, STG installed a pie-cut stainless-steel exhaust system fashioned in a two-one-two configuration. The mid-pipe wears gold heat wrap to prevent the rider’s leg from getting roasted, but the rest of the exhaust is nicely exposed in all its glory.

Finally, the color scheme chosen by Marcelo and Germán is fairly simple, yet undeniably intriguing. It employs a dark shade of burgundy on the fuel tank and rear fender, while items such as the frame, fork lowers, and faux oil tank were all painted black. Ample contrast is provided by stainless-steel exhaust plumbing, as well as the polished and chrome-plated parts found all over this bobbed GN250.
