Look at my car licences and I could ride 50cc my push bike can out run it. need some thing a bit more energetic may 100 or 125 but then I had to take a CBT just as well as I had never been on a motor bike I past easy first time on them death traps, I now love it so much the bike is freedom and the riders view is better that the car so they are not as dangerous as I thought at 60+ am looking forward to the DAS
