I've had liter super sport bikes, Can't take that riding position anymore. Don't miss the power at all since you rarely use it or need it anyway. I've always like 500 cc motorcycles. One of my other favorite bikes was my CB550 Honda back from the 70's. This little 500 gives such nice smooth delivery and the suspension handling I find as good as anything else I've ever own or ridden.
These bikes are often purchased as a starter bike or considered a starter bike. I purchased it because I find good attributes with 500cc motorcycles that I prefer.
I've got a Triumph Bonneville for my long trips. Although this 500 could be used for that purpose, I've already done a couple 350 mile days with it.
