Tony O on 04 Jul 2016 asked "Hi mark can a piston like this one fit a standard con rod and 150 barrel how much mods are needed to make this work? I have a decent Spanish Li 150 cylinder and need to get a little extra from it it would benefit from a new crank and hope to for a bgm electronic kit a decent clutch system and improved gearing via the sprockets help !!"

MB Scooters Ltd replied: Yes you can fit this piston, but would best be done to a 175 cylinder but a 150 does work. It would need a head modifying to suit. This piston needs a crank with a 115/116mm con rod. Gearbox wise the Spanish Special is not the best
