First big bike for commuting

[Dennymc123]

Hi Sorry if this is the wrong part of the forum to post this,
Im sure this has been asked a million times before but:
I've got my full licence after 8 years of 125's and want a big bike primarily for commuting to work but also one that is fun.
I will be getting a 2k loan to buy the bike so want something I won't be bored of for a few years.
I like the cbr600's but are they good for commuting and what are the maintenance costs like?
I have don't bits and pieces to the 125's I've had so can probably do basic bits but are tires etc too costly for this to be practical?
I'm not that tall so I know that will rule some bikes out straight away.
Also what mileage should I look for on a second hand bike? I know service history is important but are there any other red flags to look for?
Thanks in advance 👍

Hi
Thanks for the reply
I will be using a roads mostly and won't be going through London at all, parking is open but fairly secure as the offices face the car park and I have a lock.
Any views on what kind of mileage I should steer clear from? I know a lot of bikes are classed as indestructible but a guide would be handy

I've found a really nice looking sv650s on eBay from a dealer, 21k miles and 2001 reg.
Says service history but I will check if it's full.
Bright yellow but I can live with that!
Thanks again for the help
