Though it’s been nearly 40 years since the company closed its doors, Spanish motorcycle marque, Ossa is still fondly remembered by vintage trials and dual-sport riding enthusiasts. Wanting to honor the now-defunct Barcelona-based manufacturer, fellow Spanish outfit, Fuel Motorcycles have whipped up an immaculate flat tracker build based on Ossa’s Pioneer 250, dubbed “The Green Wasp.”
The quarter-liter project was inspired by Triumph Trackmaster dirt oval racers of the 1970s, and as such sees the Spanish single treated to a host of traditional tracker bits including front and side number boards, fork guards, tracker bars, a midcentury-style two-piece leather saddle, and a fiberglass Trackmaster tank adorned in a sparkle-green paint job. The Spanish oil-burner has also had its original Betor forks swapped out for a 41mm front-end off a Kawasaki, while it’s wheels have been replaced by fast and left-friendly 19-inchers fore and aft. The piston-port two-stroker also sports a new respiratory arrangement with a fascinating intake setup and an absolutely gorgeous expansion chamber two-stroke pipe. There’s also a set of YSS rear shocks, Ducati master cylinder, competitor-style tethered kill-switch, and a full front-brake delete.
