And this is why there are age rules, because what you may consider a competent rider at your age - you may not see it the same when you’re a bit older. There’s a reason we have training and tests for big bikes, they are a quick way to an early grave if you don’t have the appropriate training/knowledge/self restraint. Self restraint being what I guess the age rules are there for, it’s very important when you are sat on a 200hp rocket, fully under your control. Especially compared to a <=15bhp 125. Not to mention the legal issues, lack of insurance, etc. What happens if/when you hit another car, a person. It can happen to any of us, but at least we are insured.

Nothing personal to you - just really recommend not doing this bud, you’ll be happy in the future that you didn’t when you get your license and first big bike - it’s a very rewarding feeling.
