The 2004 R1 was a ground-up redesign with a shorter-stroke, larger-bore engine tilted forward, a lighter Deltabox V frame and a truss swingarm. New features included ram-air, radial front calipers, an underseat twin exhaust and a factory steering damper. Weight dropped and power rose to roughly 170-180 hp depending on ram-air.
