    I would suggest a 2006+ GSXR 750 since they make great power (150 crank HP), are dead reliable with the exception of the typical janky Suzuki R/R & stator, and have changed little since 06 until the present day. This makes parts really cheap if you need to replace something.

      Scary power! Kinda the reason I'm thinking about 600cc.

        Well, that's 150 peak crank HP, 130-135 RWHP. Perfectly tractable, linear power.

        That extra 150 cc of displacement gives the 750 has much more usable torque at street legal speeds than the 600, which is pretty much gutless below 8000 RPM.

        You have to keep revs high on the 600 to get decent acceleration. On the track this isn't an issue but on the street it's annoying.

        I've had both a 600 and a 750 motor (late model GSXR 600/750 bikes share the same chassis) in my bike and greatly prefer the 750 since it is equally at home on the track and street. Perfect blend of power and graceful handling.

          I've never ridden a 600...but the Y2K/750 was awesome on the street. Of course, I never pushed it to its full potential: 135hp.

            I absolutely love my 750. Keeps up with all of the litre + bikes in my area. Lighter, and handles better. Plus it's at least 10 years older than most of the sport bikes I ride with. The power curve on the 750's is about as perfect as they get. As stated, the 600 needs to be screaming to wring the power out of them. I always wondered why these punks cruise around in 2nd gear at 7000 rpm, until I rode one...
