PISTON KIT 73.50mm 1978-1981 SUZUKI GS1000 WISECO 4066M07350
Forged piston kit sized at 73.50 mm to increase displacement to approximately 1100 cc when used as a complete set of four. Designed with a 10.25:1 compression ratio, each single-cylinder kit includes piston, ring set, wrist pin and circlips, and requires cylinder boring to suit the oversize. Features forged aluminium construction for strength under sustained thermal load and a dedicated ring pack for the 73.50 mm bore size. Supplied with piston, rings, wrist pin and circlips. Specifications include a bore size of 73.50 mm, an oversize of +3.50 mm over standard 70.00 mm, a compression ratio of 10.25:1, an air-cooled inline-four engine configuration reference, a stroke of 64.80 mm for displacement calculation, and a resulting displacement of approximately 1100 cc for a set of four. Installation note: cylinder boring and correct piston-to-bore clearance required.
