This thread has one. It needs a bit of TLC. Still if the S4R are worth £5K then you would have £3K to use to make it perfect...

Painting a tank, tail & nose fairing is £350 or less including decals, wheel painting is £100 for a pair, a refurbed seat £120, Maxton forks £500ish, major service £1100. Plus it might be a fun project for the winter!
Inccidently I don't know the guy or the bike in question but simply thought it might be of interest to you
