Welcome to the forum. In terms of tyres, a set with a 130 front may be difficult to find, but a 120 front reportedly does the job well. I'm on my second replacement set, previously Bridgestone, now Dunlop Roadsmart IV. I managed to get them at a good price last year off ebay, the front being new and unused, but 4 years old for £75. Probably not many bargains like that, though. I would say that if the tyres are not cracked and look good, then use them to get used to the bike for as long as you're happy - I recently bought a VT500FT with tyres that are 20 and 18 years old, with one being effectively new in terms of appearance. I was going to replace them straight away, but decided to see wat they were like, and they grip just fine, so may replace them next year...
