I am looking at probably getting a midsize motorcycle in the future but have very little interest in a large Maxi Scooter. I'm not saying there is anything wrong with Maxi Scooters, just that for my style of riding, a motorcycle would work better. It all depends on how you plan on riding it.
Unlike most here in Battle scooters, I prefer a manual transmission over auto. I have come to like the CVT's on my small scooters, especially around town, but on the mountain roads I really like riding, a manual just works better. I also like to ride off the pavement and scooters just don't have the suspension or ground clearance of something like a DL650 or Versys. They also don't have enough cornering clearance for me except maybe the T max.
Where the Maxi Scooters have a big advantage, IMO, is for touring. The Maxi's have great built in storage, good wind protection and comfortable seats. If I wanted to do a lot of long distance two up touring I'd be looking at something like a Burgman 650. IMO, The Burgman is more of a replacement for something like a Gold Wing rather than a midsize motorcycle. Compared to a Gold Wing, the Burgman suddenly looks pretty light weight and inexpensive.
However, while I have owned and/or ridden hundreds of motorcycles, I don't have that much experience with Maxi Scooters so I may end up changing my mind and getting one in the future.
I ride, Therefore I Am.
