maintenance is enormous sums of money. I think the c400 wont be far behind. check to confirm.

I would not be able to hold on to a maxi scooter if I didnt do the maintenance myself. its actually also much easier on smaller scooters. parts on maxi scooters weigh substantially more. the exhaust on the maxsym 600 weighs so much vs my sym hd200
even rim and tire is much less weight.
I did at many times look at the bmw 650 sport. but asking prices are not reasonable. and getting parts is expensive and not the easiest and most available.

Yes, we've seen insane prices quoted for BMW C650 servicing - 4 figure sums! If anyone is thinking about one, they should ask their BMW dealer some searching questions, or have an alternative worked out.

4 figures...pfew thats just nuts.

when I was looking to get one, I couldnt find a service manual. so basically that made up my mind.
if I was looking for a premium scoot id consider the honda sw 600/400 as a contender. they arent cheap either.
