These cylinders are more modern versions of the 2-port Vespa Sprint 150cc cylinders and make great performance upgrades for ALL 2-port rotary valve models. When used with a Sito Plus exhaust and a 20/20 carb, it's common to reach speeds of 50-55 using a 3-speed VNB engine! You'll really appreciate the extra displacement in the wind and when traveling two-up. Highly recommended for VNB, GT, VBB, VLA, VBC and similar engines. Cylinder head (part # 90970) not included and is required if not being placed on a Sprint!
Cylinder assembly Includes cylinder, piston, rings, wrist pin and circlips.
