I came across a post from an Australian review site from the owner of a Citycom 300 who had traded it for the new MaxSym 400. The short answer is that initially he was very disappointed. The 400 is much slower off the line, has less storage space and uses more fuel although he says he's getting 350 km from a 15 litre tank so it can't be that bad. The larger 400 won't filter through traffic like the smaller Citycom; big surprise. On the plus side the 400 comes into it's own on the freeway at 110kph. It's much more relaxed running at lower rpm and is more stable in traffic, not getting buffeted around as much. He likes the seating position on the 400, he can sit forward in calm air behind the shield and this makes the bike very stable. Personally I find this is also true of my Citycom. Moving forward on the seat even a small amount makes the bike much more stable and I may not be sitting in still air behind my shield, but there is no buffeting. There was a complaint about the Citycom running close to redline at freeway speeds and the 400 having decent passing power above 110 kph which the Com doesn't have. If we are talking optimistic Korean indicated speeds; my Citycom cruises at it's best at an indicated 120 kph at 7000 rpm, still well below redline. It is true there won't be any passing power above that but the bike runs well up to that point. It was a thoughtful post full of interesting generalizations but no specifics as to speeds and rpm's between the two bikes. Still, a lack of storage is a lack of storage and gutless is gutless, so now I guess I won't be pining for the MaxSym.
