could not agree more ride your 125 for a bit and get some road use, this is exactly the same route I took. Never been on a bike until May this year and did my CBT ------AND I WAS CRAP

On the advice bought a 125 (intruder lc) put a few miles on it and enjoyed the roads, hills and valleys round Brecon.
Booked my theory test (did not revice-----AND FAILED)

re booked my theory (read the book -did on line tests and scored 49 out of 50)

Tried to get in on a 125 mod 1 but it was very busy and did DAS but failed Mod 1 first time. Had a think??????????????
re booked mod 1 and passed with no worries, booked mod 2 passed last sat no issues at all.
chuffed ain't a word for it, and I believe the time on me 125 was well worth it- even sold the bike and only lost £50 from orig purchase price ---winner
now looking forward to dry days and open roads
a very happy man
