I seriously doubt a sportbike is going to make you a better rider. I have been able to keep up with everybody I've ridden with on my 650 Strom in the twisties (although not on the straights, of course). That includes liter class sport bikes. Most guys will not ride their liter bike to the bike's limit, and I do ride my Strom to it's limit. I took it down to Beaverrun and found what it was capable of, and my confidence in the bike is much increased. Why don't you do some track time on the bandit and see what it can do? It might surprise you just how capable it is, as well as build some confidence in the bike and your ability. It's a lot of fun to ride a sporty standard really fast and freak people on sport bikes out. On one ride with a friend and one of his friends (both on literbikes- GSXR and a Honda CBR) I took my little Strom and left them 1/2 mile behind. When we met up they were laughing and shaking their heads... the one guy said "just proves you never know by the bike". Truth was, I knew the road really well and they didn't so I had an advantage, but we were at 100+ through some of the sweepers, by their speedo. I can go as fast on my little 650 in the curves as I would dare ever ride on the street. It's not the bike... even a sporty standard has enough on the street if you know how to handle it. Just a suggestion... do what you want.
