Honda CBR400 is an ace little toy to learn on. Cheap to run and insure and quick enough to lose your licence on if you are that way minded. Very manoueverable and nimble in corners which means that before you have developed Johnny’s ‘Sixth sense’ it should be able to get you out of most tight spots that the loony car driver in front puts you in. Also makes it ideal in the cramped city streets.
Alternatively the bike I really started on was a Kawasaki ZZR 600. Very comfortable bike which can do a bit of touring, a bit of city work and can scratch with the best of them if needed.
As for safety I am bang alongside the other esteemed authors here. ALWAYS wear a full face helmet, leathers, sturdy boots and gloves. Trust me, do it. Several of the most favourite portions of my anatomy have been saved by following that advice. As Johnny said you never know what the guy in front is going to do so don’t take the chance. The long and short of it is that if you ride defensively and take sensible precautions you should be as safe as pretty much any other road user.
I’m afraid I can’t really help with costs as the UK bike prices are extortionate but you should be able to pick up a good quality second had 400 to 600 cc bike well within your budget. I would bear in mind running costs though, you can go through a decent rear bike tyre in 5k miles if you are not careful and they can cost a pretty penny, servicing can be expensive on a fully fared bike due to the time involved in taking all the pretty plastic bits off just to get to the engine. Invest in a decent chain lube kit as it’ll save it’s money in one set of chain and sprockets.
Good luck and have fun.
