I also think that there should be a tiered licensing system. Although I am sure that I wouldn't feel this way if I didn't already have my license (and I jumped right to a 750cc road bike from many years on dirt bikes), I really think it would be a good idea. I think that they have gone way over board in the UK with starting off on a 33 hp machine (I think that in many instances 33 hp would be more dangerous than 133 hp- not enough power to get you out of trouble). I think that one should take a test, then do at least a year on a 250cc machine or less. Then take another test, and do at least a year on a 600cc machine or less. Then take another test to ride whatever they want. At least this way a rider will have a minimum of two years of experience before getting on something like a 'Busa. Maybe one more step would be a good idea too (250-400-600). I don't know. It just scares me that somebody who doesn't really know the clutch lever from the brake lever yet can jump on something like a 'Busa right off the bat.
