Here in Holland, when you are over 18 and under 21 years old, you have to have a restricted bike for 2 years, max 25kW
You don't have to take a new test , when you upgrade to a > 35kW bike
When you are over 21, you can take your test for an unrestricted bike.
so my son is 18 years old, and his Yamaha FZR600 is 1 month older than him.
We've just painted the wheels, mirrors and changed the front tire and chain/sprockets
He's good to go.
My bike needs a little more care.
New chain,new sprockets, Goodridge Braided Lines , new front brakepads.
A complete cleaning and polishing, after this winter, (a lot of roadsalt, and bad, cold days).
I also have to clean the inside of the headlamp glass.... it has a haze inside.
I must take care of the frame-crossbar, just under the radiator.
It looks like it's starting to rust.
Cleaning and polishing the exhaust manifold with kachelpoets (

polish for old cast iron stoves, to make them black again)
I'll post some pictures.
Still have 12 weeks to get the job done.
Hopefully next week, I have the brakelines, so I can strip the bike clean of all the plastic , and get to work.
