I've just bought a Bolwell Retro 50cc scooter and being totally new to riding motorised on two wheels I've found it really great. One thing I've found with the Retro is that the speedo is 10k's out. I realised this after a few days when I noticed that cars were passing me when I was going at what I thought was 60 but I was really going 50. I confirmed it by going out for a ride with a friend who was on a motorbike and told him to go at 50kph. Going neck to neck with my friend my speedo was showing 60. Has anyone had similar issues with Sym scooters.
