Got a Kymco Super 8 50cc 4-stroke scooter from 2007-2008 that needs an engine refresh? This complete cylinder kit has everything you need! It's made by Citomerx (part number 150388), and comes with the cylinder, piston set, gasket kit - basically the whole shebang for a rebuild. The cylinder has a 39mm bore, chain tensioner hole spacing of 40mm M6, and the piston includes 4 rings (rectangular profile) with a 13mm wrist pin diameter. It's designed to fit 4-stroke China GY6 / Kymco 139QMB/139QMA engines. The finish is matte gray, corrosion-resistant, and built to last. Dimensions are about 115x110x70mm. Best part? It comes with a 2-year manufacturer warranty! This is brand new, ready to install, and can be used with your original cylinder head. Perfect for DIY mechanics or repair shops working on scooters. Whether you're fixing up an old Super 8 or doing performance work, this kit gives you reliable OEM-like quality without the dealership price. Just make sure it matches your exact model year!
