The use of batteryless electronic injection helped OSSA’s engineers move key parts of the TR280i to more strategic locations. Similar to what Yamaha did with its YZ450F, the top end is reversed, with the intake at the front and exhaust at the rear. The cylinder is tilted rearward 35 degrees, allowing lighter parts such as the air filter to be placed higher. The fuel tank is located on the front downtubes of the aluminum/chrome-moly frame where you’d normally find the radiator; the radiator, meanwhile, sits behind the tank.
