Dave,
Stay the F away from a liter bike for the track. almost every single person that I know with a liter bike has gotten on something smaller (600 or 750) and gone faster. a literbike at the track in the hands of anyone who isn't an expert level racer, is just a speedy ticket to Highside City. get a 600 or what might be the ultimate track day bike, a late model GSXR-750. parts are cheap and plentiful if you crash. there's a heck of a learning curve to transition from a twin to an L-4, but after you figure out that it's all throttle control, throttle control, throttle control, it's a lot of fun.
if you want to stay in the freakshow, you really can't go wrong with a Triumph 675 which is really the best of both worlds, plenty of torque at 7k+ rpm with a big hit of horsepower up top. it won't be any cheaper to go boom on than your Aprillia, though.
good luck,
Lance

Actually, Twins are very linear and they put power down in a very forgiving manner. Therefore they are easy to ride.

A 600 would eventually be faster then the aprilia because all the new 600's are more capable then any twin on the market. You just need to develop the skill to ring that performance out of the bike.

I'd go for a 600 over a 1000. Any newer 600 puts out comparable power to your aprilia. I recommend a 600 though because it will help you work on cornering speed which is what the track is all about. Riding a 1000 is very challenging due to the power output of the bike, not only do you have high peak HP, but also a lot of torque to manage. Additionally just the speed the thing carries down the straight will be a lot more than what you're used to. So most likely you'll be braking harder and earlier. When you are riding around the track and directing the majority of your attention to throttle inputs that is going to handicap you in another aspect of riding. Additionally a 600 is more forgiving, a 1000 is not. If you're not expecting the bike to do something, especially when putting the power down, it will bite. Or you'll be riding in fear of this aspect of the bike which will hamper your confidence in yourself and the bike therefor slowing you down. But ultimatly it comes down to you, you can buy whatever you will like, but I believe a 600 is better in the long run for learning the finer aspects of track riding.

Stiffy has some good points.

Even though you're used to riding a twin, trying out an inline 6 will be just as much fun and a lot easier to find parts for and repair at cheaper cost then your current bike.

Keep the Aprilia for the street and get yourself a track ready 600cc. You'll be glad you did

i'd shop around for an '05-06 600rr or r6.
