Now there's a question, and a damn hard to answer one at that.

Not many NSR's fetch good money these days, Repsol '28sp's maybe but even '21sp's only command around £1500 for a tidy one.

To be honest and it hurts to say it but I'd be plesantly surprised if you got near a grand for it selling it properly (i.e. advertise it and wait).
But if it must go and you're going to Ebay it (and I feel like I'm insulting you here cause it looks so nice) maybe £700??? Reserve at £500?

Really I hope I'm wrong and it fly's past a grand but I can't see it.

And please change those mirrors they look horrid.

'16 with a '21 engine eh? Surely it want some period bodywork and a replica of this doing?
