I agree with those who have said its a good thing but has include cars,they have this sort of thing in Oz and New Zealand when they pass their car test.
If i think about when my boy will be 17,in 11 years time,how light will the GSXR 1000 be then? and how much HP will it be making?they do need to do something.
I remember having a go on a mates TZR250 when i had my 125 and ended up on the other side of the road hitting the curb when I got to the first bend.
If they didnt have licence restrictions in Japan we might never have got 250's or 400's.
