My medical cover (6-months) only covers me up to 125cc and I have passed my UK motorcycle test albeit 40 years ago so I have a class A.
The scooter in the picture is a 125cc and the step thru motorbike is a 100cc - with 2 of us on it I suppose the 125cc would be the best bet if we want to go up a slight incline - although both manuals say they will carry 150 kgs???
