Don't waste the cash. You'll be frystrated at it's shortcomings pretty quickly, if your going to be doing your test reasonably soon.
Me, I was never interested in motorbikes at all really, but bought a simple 125 to get to work on, as 90mpg appealed when my alfa was giving me 23…
But within a couple of months, the wind blowing you off the road, the other motorists riding on your rear wheel, and the lack of get up and go, or proper stopping, meant I did a test simply to get a more stable comfortable bike.
I was a "nervous" biker, but still regret taking so long getting round to doing my test, doing 8 months from the cbt one august bank holiday, to my first test and DAS course the following easter.
It's hard to be cool on a 125, so don't bother.
