Gerry you should consider the clearance between your knees and the wheel. If you are tall or have long legs a smaller wheel may be of assistance. Clearance of the instruments may be another concern to consider. If you like an unobstructed view you should consider while size of Mota Lita allows for this. Finally the smaller the wheel the less easy it is to turn at slow speeds.
I trust this will be of some help and wish you many happy miles in your new Mog.
