01 — Overview
A GP500 factory machine used in 1994 and 1995. A change of frame material optimised rigidity balance, and moving the air intake from the nose to inside the cowl improved aerodynamics; the 1995 version adopted ram-air pressurisation of the airbox. Liquid-cooled 499 cm³ two-stroke V4 with crankcase reed induction and a 6-speed gearbox.

ENGINE
V4
Four cylinders in a V — multi-cylinder performance in a narrower package. A power stroke every revolution: light, simple and explosive — and, as emissions rules tightened, gradually retired from road machines.General description of the layout
