To be fair, it’s not a huge price for a bike in that apparently good condition. I’m sure you could negotiate it down a couple of hundred? Given the mileage and condition, I’d imagine that the suspension won’t be too tired at that mileage, so you could put that job off for a while. But you’d still need to budget for it and if you’re thinking of doing a lot of two up work with your other half, I wouldn’t wait to get that done.
What I would want to get done straight away though, would be to replace the standard brake hoses after 18yrs, with some braided ones. So budget for that. HEL do some sets for around the £100 mark iirc? Don’t forget to use the Forum discount code. Don’t ask me how I know that!
If I were to decide to sell mine, (which I have no plans to do), which has pretty much all of the common mods / updates on it, along with a set of luggage, I wouldn’t let it go for much less than that.
So, if you hold out and maybe post a wanted advert in here for a fully specc’d one, you might get one offered for similar money? It would save you a load of hassle and money if it has had all of the main upgrades done already? Plus, most forum owners will have maintained the exhaust exup valve as well.
Good luck with your search.
