Motorcycles no longer race at the International Pikes Peak Hill Climb, and more’s the pity. The unique race inspires gutsy engineering, and you used to see the gnarliest of machines in the pits of the independent teams. It’s those bikes that inspired this aggressive Royal Enfield 650 street tracker from STG Tracker in Argentina.
Nicknamed ‘Crow’, the build was an official commission from Royal Enfield Argentina, who supplied a brand new Continental GT 650. STG then took it, bumped the motor to 865 cc and trimmed over 80 lbs of fat.

STG’s workshop is based in Buenos Aires, and run by Marcelo Obarrio and Germán Karp. The crew have built bikes for Royal Enfield Argentina in the past, but wanted to up the ante on this project. ?Most of our customizations are trackers, brats and scramblers,? says Marcelo. “We wanted to make something different, and chase the best power to weight ratio.?

?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!?

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 p...
