Here ya go. Alian makes a pipe but it may be a custom jobbe for KSport cycles., but you can get it there. Second, the factory 150 kit consists of a cylender, piston, rings and all the gaskets ya need but is a rip off at $449.00 and only adding 1 horsepower! The best bang for the buck on an MZ 125 is get the cam advance kit from KSport, which consists of a jet kit and the tools needed to advance the cams and buy a 1 tooth smaller countershaft sprocket, and pipe, the thing will be a brand new bike. There is a kit in the works , 170cc, cams, and u can order a Mikuni TM (flat slide) 28mm carb, and do a little porting and it will pull harder than you ever imagined! The kit is going to be available from POweroll soon, I'll keep ya posted as I am in personal contact with the developers there. Please feel to PM me if your dealer needs any more advice, I love this little bike and know quite a bit about it!
