If your Downtown suits you that's great, but in terms of service interval it is decidedly inferior.
This isn't opinion, its a numerical value.
Both scooters have their plus and minus points.
Service interval is where the Honda wins, valve clearance adjusters for ease of home servicing is where the Kymco wins.
I've done 12,000 miles on my Forza, two services, three hours labour, scooter off the road two days.
If it had been a Downtown at five services including a drivebelt change, the bill would easily have been double and off the road five days.
The respective merits of dealerships in your local area is really not an issue for the vast majority of us.
