motorway riding
 

what is the least cc you can ride on a motorway? just wonder'd.

All vehicles have to be in excess of 50cc, (and have a minimum speed of 40mph, I think...)

.

50cc but you must have a full license.

i have had my licence 45years, i was just wondering if i could use a motorway on my 125.

Yes Bill no probs.....................

Though mine didn't like it much :)

My daughter used to own a teeny-weeny car with a teeny-weeny
engine: Subaru Vivio 4WD 600CC 33hp. Theoretically that car could go
on any road but in reality we tried to avoid motorways. Just unsafe
with such a small engine.

Going onto a motorway on a 125CC bike appears to be legal with a
full license but I personally would try to avoid doing this.

I'd say it'd depend a lot on the bike. You waouldn't want to do it with a 2-stroke 125, especially a low power one (scooter) or restricted one, that'd be asking to seize it. And you wouldn't want to do it with my old 125, because it was rubbish. But a solid, good condition 4-stroke shoul be fine. Depending on the bike you'll quite likely not make 70mph, but that was never a concern for me when I did it. I rode daily on a 60mph dual carriageway and the only time the lack of power wqould ever be an issue is if I did something ridiculous, like try and overtake a truck up a hill.

The 125 in question is a honda CG.

Should do 65, or a few mph more if you lie flat on the tank. I actually had
a CG125 for a few days during my DAS: my instructor lent it to me so
that I could practice on my own before going onto a GS500.
