Hi, I am a little confused over belt size for Malossi Multivar 200 MHR Team (M5112645 - http://www.malossistore.co.uk/en/products/VARIATOR-MULTIVAR-2000-MHR-TEAM-SCOOTER-PIAGGIO-_5112645) and Malossi Rear Pulley System (M6113101 - http://www.malossistore.co.uk/en/products/REAR-PULLEY-SYSTEM_6113101) for a Gilera DNA 50. I believe the rear pulley is generic for Piaggios with long or short cases, as the Gilera DNA has a long case, I am wondering what is the optimum belt length would be? I have a Malossi 611411820 (815 x 8 x 17.5) belt but would rather make sure I have the correct length. Anyone with some experience with these kits on the Gilera DNA 50 would be great. Thanks guys, much appreciated. - Tristan
