DONT buy the xsport engine they are slow u can not tune the 120s easliy because they is not alot off work that be done to the engine if u wont a strong engine go for a 125 monstermoto engine they sell recon ones have no idea on a price www.monstermoto.co.uk (http://www.monstermoto.co.uk) :thumbs:

If you get a 125cc engine with a 52.4mm x 57mm (bore x stroke) you can get a 140cc bore kit for about £130 it will be better than most standard engines.
