Because the insurance companies will never have a big problem as long as they can charge whatever the fak they want to anyone on any kind of cc range.What does this crap really matter?
Let's get real.
If the insurance companies had a big problem they would have forced the govt. to implement graduated bikes...everyone starts on a 250 cc.
.
They're making profits off bikes. No complaining will happen
And personally i don't see a problem with an incremental hp/lbs permit, just like what europe has.
That system is part of the reason the honda 500 series was born. Can be used/sold worldwide with the same platform/engine and meets the requirements of the learner permit.
