Meet ‘Crow’, a Royal Enfield Continental GT 650 built with inspiration from the aggressive lot of motorcycles that raced on Pikes Peak Hill Climb. This street track from STG Tracker, Argentina was built as an official commission Royal Enfield Argentina who supplied a brand new Conti for the job. First notable thing here is that STG bumped the engine to 865cc and made the bike drop over 36 kg of weight. (Source: Bikeexif)
STG’s workshop is based in Buenos Aires, and run by Marcelo Obarrio and Germán Karp. “We were inspired by Pikes Peak race bikes, with that flat track seat that we really like. All aspects of the bike were redeveloped with the goal of performance. Not just to look good, but also to behave well on track. We are not experienced track riders, but we have fun chasing the apex. And this bike is street legal too,” he says. (Source: Bikeexif)
The Crow’s first run on the dyno produced 74 hp and 80 Nm of torque—a significant jump over the stock bike’s 47 hp and 51.5 Nm. To get there, STG used an 865 cc big bore kit from S&S Cycle, along with ported heads and an S&S camshaft. The upgrades also include new Rekluse clutch plates, a Gorilla quick-shifter, a larger aluminum oil cooler and K&N pod filters. The exhaust system is a combination of headers fabricated in-house, with an S&S muffler designed for the Indian FTR. There’s a carbon fiber heat shield to keep the rider’s boot safe.

STG also upgraded the Royal Enfield’s running gear to match its new output. Up front are the forks, brakes and front wheel from a Yamaha R1. A CNC-machined top yoke holds everything in place. The swingarm, rear wheel and shock are all from a Yamaha R6. STG fabricated a new subframe and upper shock mount, and shortened the new swingarm to match the Enfield’s measurements. Both wheels are wrapped in Dunlop Roadsport 2 rubber. (Source: Bikeexif)
There’s a long list of carbon fiber parts on this build, and they’re all custom. STG designed molds for the parts themselves, then sent them to a specialist that makes carbon fiber stuff for professional rally bikes. The OEM fuel tank remained, but was modified with the top section of a Honda VF750 tank. STG also installed Kraftec rear-sets, a CNC-machined rear sprocket, and a full set of Hel brake lines. Thoughtful details abound—like the laser-etched ‘STG’ and ‘Royal Enfield’ logos on the fasteners that are sprinkled across the bodywork. (Source: Bikeexif)
