i'd recommend having a crack at the test over easter - apparently the mod1 and mod2 are tricky to do really close, and you could loose half you summer. Get as much done at easter as you can, then you'll be ready to rock and roll in the summer!
As a point of reference, I'd only ever done a cbt before starting my direct access - two and a half days of training later I had my licence!
You'll find the bike alot easier to work on than a car. I think it's pot luck with the electrics. Mine was an ex race bike i think, tell tale marks on the fork lowers and gear lever, and either aftermarket body work (though excellent) or a respray (again, excellent), only given away by the tiny "motografix" badges here and there. Yet despite a slightly chequered history it felt sound and I was getting good vibes from it (I've bought a rust bucket before, and i didn't get such good vibes. Result; blown rear shock 144 miles later, exhaust collapsed 600 miles later, reg rec, wheel bearings, brake discs, fork seals etc have all also blown over the last year or two, but she's still going!)
Anyway,the zxr has been faultless up til now, cheap to run and insure. I'd sell you mine, but last week i think it decided to blow its hg, and even then i'd want more for it than you'd wanna pay - xenons, braided lines, hugger, new tyres, pads etc!
Anyhoo, good luck on the search for a bike - keep your eyes on the class ads section on here, dealers want far too much for one. And budget for good kit too, enough to get you on track days if you want. No point buying one set of kit, then having to buy a second just to get on track. Especially when a spring/autumn trackday (say 7x 20 minute sessions, with instruction) is less than £100!
I do 700 miles a week in all weathers including snow, that's roughly 35,000 miles a year, and some weekend warrior biker has the nerve to get out of his Audi at work to tell me to I was riding far too fast in the wet (over taking at 50... fast eh?).
