Well the CT110 hasn't really changed much since the 60's so I think it could be about due for an update.
And a few people have suggested a bigger engine or bikes with bigger engines, but I am pretty sure a bike has to be 110cc or less to ride on a footpath (along with other restrictions), so a bigger engine would be useless.
