1000's are more prone to whoop your ass than a 600 SS

600's are rather tame until your over 8k, and really near 12k to be in real powerband (not including the 636 which has more torque lower down revs). But the CBR and GSXR I rode where on par w my Fz6r. Fz6r actually had more torque, but cut out at rev limiter right where the SS's just start their real power.

Brakes-- yeah brakes can easily bite you.
Stock 250/300 brakes can lock up easy enough also..especially if jab at or hamfisted.
Any bike will go down from hamfisted braking, I doubt ABS can save that either.

Anyway, if this guy has so much money and market has changed so much in way of what bikes are available.
An Fz6r or CBR500/650F or fz07 would be good starter bikes and have more longevity in most people garage. (eg. won't get bored w power fast)
