the french rules are pretty complexe on tis subject & I'm not really au fait with them having never been concerned. As I understand it, in france you're restricted to 33hp for 2 years following your test, UNLESS you were over 21 when you took the test at which point you're not restricted. For one year following the test, I think you're supposed to display an "A" on the rear mudguard "Apprentice". I think that so long as you're legal in the country of registration, & that is a country within the EU then you'll be ok (otherwise no english bikes would be allowed cos in france we're restricted to a max of 100hp!).
The speed limit on the "routes nationales" (single carriage way main roads) is 90kph (55mph) unless indicated otherwise. The autoroutes limit is 130kph (80mph) but is automatically reduced to 110kph (68mph) if it's raining. The autoroute also has a minimum speed limit of 50kph.
The speed limit within a town or village boundary (white name sign with red border) is 50kph (31mph) unless indicated otherwise. The exit from this zone is marked by the same name sign but with a red diagonal line through it.
I can probably find out more details with a little research if needed.
Basically Merv, so long as your licence corresponds to the machine you're riding then you're ok.
