SK? and is this a good deal?

When I first started looking to buy an sv I thought that SK meant the year/version of the bike but recently I have been doubting that because I have been seeing 55 plate bikes that are SK3. Can someone explain what SK means please. Thank You.

I also think that I might have found my sv, The details are that it is an 07 SK6 with 2000 miles on the clock, completely standard mint condition and the asking price is £2400.

Can anyone better this? What are your opinions?

I would want to buy things like tail tidy, crash bungs, alarm/imobiliser/dot security system for it I would also need to buy insurance and all the clothing as well so it soon ads up.

On ebay last week a 2009 in grey (my favorite colour) went for £2800 but that is out of my budget sounded like a great deal though.
