A friend of mine has these forks for sale. They are std 2011 Daytona forks with Bitubo ECH Gas fork internals, they will fit any Daytona up and including a 2012. May fit 13+ but I cannot say for certain I think the only different is a different offset so you'd need to use the 13+ yokes. They were serviced prior to purchase and then not used approx 18mnths ago. This is for the forks and yokes NOT the calipers. He wants £1000 for them if you know what these cost then you know thats a good deal, would prefer collection from Northamptonshire so that you can see them and no exactly what your getting before parting with your hard earned.
This won't be very helpful, but I had a set of these Bitubo forks, exactly the same spec and also rebuilt. Complete with yokes and steering damper. Listed for months on Ebay at £600, and I still have them.......
