Yes there Nikons, can't make my mind up wether to have then nikel plated or buy some Lomas pipes
yes it's a ZX6R 05 front forks, ZXR400 H Model yokes machine to accept the forks with a zxr front wheel, no speedo at the minute but probably going the electronic speedo and rev counter route
initially, I had standard ZXR400L forks and they seemed very hard and choppy. I then put the 636 forks in and had them revalved by Mick Gardner racing and they are very smooth indeed and less inclined to shake its head, springs are still standard (I think).
I also found with the ZXR yokes and wheel, I couldn't fit a speedo either, but as its a track bike it didn't matter.
Koso do some nice digital/analogue clocks though
