Thank you all for your post and and input, especially Mark … and with that I have decided to get the K8! 
It even has 6 months warranty, but will need to get new levers, screen, exhaust and gel seat (for my bony ass) 
Congrats on the new purchase, enjoy!
Thanks … and looking outside, seem perfect timing! 
Really enjoy my gixer, no problems at all, always puts a massive smile on my face. I get about 172bhp at the back wheel, thats with a taylor made exhaust, standard ECU but with a custom map on it. I will be get a power com very soon.
Done trackdays and touring on it and it f**king great!!!
Save yourself some money and buy the best GSX-R 1000. The K5 or K6.
Use the money you save to invest in quality suspension (could probably get some Ohlins or KTech fork cartridges and shock).
Best engine (the power is lower down and the top end difference between K5s and later models isn’t really noticeable), least weight.
Buy one off a fair weatherer and could find one with mileage under 4k.
Do it
Think he already bought the K8
