And it doesn't get much more serious than this: the 2Fast 100cc Derbi D50B0 cylinder.This high-end race cylinder pushes an unbeatable 100cc displacement, made possible by a 52 mm bore / 52 mm piston (with 14 mm wrist pin) and a 47 mm stroke (for 95 mm conrod). The Nikasil-coated aluminum cylinder comes with 6 transfer ports and a split exhaust port. It’s paired with a two-piece cylinder head, featuring the signature blue anodized cap.The 2Fast 100cc kit ranks among the most powerful +80cc race kits on the market. That means it needs the right setup: a matching exhaust is a must, along with a bigger carb and a quality inner rotor ignition.Note: To make room for the wider cylinder base and long-stroke crankshaft, minor engine case machining is required. You'll also need 107 mm cylinder studs.Specs – 2Fast 100cc Racing Cylinder Derbi D50B0Aluminum cylinder, 52 mm bore / 47 mm stroke / for 95 mm conrod1-ring Vertex piston, 52 mm, 14 mm piston pin6 transfer ports / large bridged exhaust portAluminum cylinder head, 2 mm squish clearanceCompression ratio: 1:16Case machining requiredNot approved for road use
