Question by Colin: Engine size restrictions on motorbikes?
When i was issued with my full UK driving license in 1987, my provisional entitlement for motorcycles was 250cc.

I used this size of bike for the three years before i got my car test.

Then years later the restriction changed to 125cc.

Does this mean even though i had my license and was able to ride 250`s, i now have to go down to the 125`s?

Thanks

Answer by Biged
Yes! Years ago a 250cc was less powerful than a modern 125cc, so its really a power thing not an engine size.
I had a similar problem, I had owned for years a classic 250 cc Royal Enfield, which i could ride on my provisional licence. The law changed and i had to take my test to continue riding it.

Markus, It can be anything which creates propulsion. And I personally would probably not consider “heat” to be pollution.
