I friend of mine has a set of Ohlins forks off a 1098 for sale.
They use the radial calipers.
I haven't measured their diameter but I'm considering putting them on my 04 S4R.
I guess the big issues are
* New triple clamps needed
* New axle?
* New rotors - were the 1098 rotors larger diameter - I believe my srock rotors are 320mm?
* New radial brake calipers
* Are the rotor offsets the same?
or should I just can the idea and go buy a pair of R&T forks from Dan Kyle.
You should shitcan both ideas. The S4R has a badass front end from the factory: excellent valving, linear springs, TiN coated sliders. BAM
* New triple clamps needed
yes think you'll need 53/56
* New axle?
yes 1098 axle with spacers most likely custom
* New rotors - were the 1098 rotors larger diameter - I believe my srock rotors are 320mm?
-rotors from 1098 are 330mm, but they use a 5mm spacer on the caliper mounts you can remove to run 320mm rotors
* New radial brake calipers
- 100mm radial calipers (any new Ducati are running them)
* Are the rotor offsets the same?
-1098 forks are 15mm offset rotors, not sure of the S4R
