My neighbour had one of those, a newer version. It was very nice. Yours looks good too, as you say it's a bit careworn but give it a service and get it to work. Also this will help in making it less likely to be stolen. You could always go for the rat look.I bought another 125 yesterday - an old 2006 Yamaha YBR125 for my son to use:
Where he lives there is a high chance of a bike left on the street getting stolen and the insurance premiums reflect that (£250 third party only for him compared to £750 TPF&T and £800+ comprehensive) so I needed something cheaper than his Mum's MSX125/Grom that he's been using up until now i.e. didn't cost a lot so not a big deal if it is stolen. The mandatory excess on the TPF&T policies (£500+) made them pointless anyway, for a bike that's only worth about £800.
It's somewhat tatty, although not really as bad as I'd expected and everything seems to work (even the fuel gauge) and it rides quite well. It's quicker than the Grom as well, so if we do a 125cc ride out together I'm going to have to work to keep up!
I've given it an oil change and will change the air filter and spark plug (as these sorts of bikes don't tend to get a lot of maintenance) plus stick a top-box on, but no real plans to do any more than that.
