Does your insurance go down a lot , I know that it does with car drivers , so does it apply the same way to motorbikes ? , also was anyone down Ace yday? lol
not sure at 21 but apparently it does at 25
It did for me mate, at 20 i was riding Bandits and Hornets and a couple of 500’s and normal non-dispatch insurance was around 600-700 TPFT in NW10 ish so not the best area, when i turned 21 i was paying 370 for the same bikes and can now insure most sports 600 for around the 400 quid mark (and probably cheaper than that if i ring around), Im 23.
It could be that it was my accumilation of 3-4 years NCB dropped the price, but i think 21 is a cut off point for insurers.

27/31?
it definitley does go down fella, i insured an R6 a day after my 20th, when i renewed at 21 it had gone down even tho id gotten points in that year 
I can dimly remember being 21… but insurance really got to be affordable at 28.
Now costs me about £200 a year for comprehensive cover on a ZX-9R - I could afford to insure just about any bike now I’m nearly 40.
Insurance and age is one of those funny things.
You get to 21 and they tell you that it will get cheaper when your 23/25. You get there and suddenly it’s 28, and so on.
You get to…er…my age, and then they want more. Apparently 40+ years experience, no major incidents, very few points (all expired), one theft claim in the last 30+ years don’t count.
I’m now an “age related risk.”
Enjoy being 21 to 50. It’s insurance Nirvana if you keep your song sheet clean.
