This is an authentic Suzuki OEM engine crankshaft assembly designed for early liquid-cooled 400cc inline-four sport motorcycles. Manufactured from high-strength forged steel, it includes the primary drive helical gear, central timing-chain sprocket, balancing counterweights, and right-side ignition rotor/flywheel. The assembly is engineered to handle the high-RPM operation of Suzuki’s early 16-valve performance engines. Compatible Models Suzuki GSX-R400 (GK71B): 1984, 1985, 1986 Suzuki GSX400FW: 1983, 1984, 1985 Note: Suzuki revised the engine cases, cooling system, and crankshaft dimensions for the later GK73A generation. This assembly is not a direct fit for 1987 or newer Suzuki 400cc sport models without modification.
