I think they make sh1tty riders... not the other way around... that sh1tty riders are drawn to them... which is usually what you will hear.

They make you lazy. You have power at the low end, so there is no reason to stress the upper echelons of the RPM dial, so when you get there you are largely unprepared. You don't know the limits of the power band because you are only there when nobody is around and you are going really fast, really straight.

The reason so many more of them crash, statistically, I believe is because they don't know how to get themselves out of the sh1t, because they are completely unaware of what the rear is going to do when they are already in too deep and need to turn, which means apply power.

It is too much for anyone who does not regularly push it.

Makes lazy shifters, lazy brakers. You don't have to carry speed into a corner, which is too scary on the street with that much power, because you can just power your way out. Usually when they start trying, they start crashing. Or if they never have, and find that a road turns a little harder than they were expecting and they wash out because they don't know what they are doing and are in the wrong gear, or they apply too much power too quickly because they don't know what they are doing. 90+mph in first. Ridiculous.
