What a bike the K5 was/is. I seem to remember you could get a new one for £8999. I had one back in 2007, cracking bike. Maybe put one on your list bradders, if you can find a good one.
According to those guys, the bike hasn't changed much since 2005. Bradders has one already (or is it a 750). I'm on ebay now! Cheap trackbike only £2,200!
I had one, race/track bike, 170hp rwhp with no traction or anti wheelie nonsense Never would work in the wet tho
The Phantom was a grey colour with a yoshi end can. I think it was an American colour scheme they used to clear the K6 stock. There were head stock issues with the K5 if I remember correctly.
