Another way to go about this is to locate a set of BMW Marzocchi forks, 17" 3 spoke wheel & requisite axle, two-piece mudguard, four pot Brembo callipers and floating 305mm discs from a K1100RS or 16V K100RS (this swap requires a 20mm K11RS master cylinder). While not inverted like modern motos they are more substantial than the F&S, Showa or other stock forks, will slide right in using the same bearing size, lockdown nuts and steering stem diametre, and you will not have changed the rake/trail or wheelbase
much (there IS a slight diff) - using anything from Yammie, Kwacka, Suzi & the lot you will not know what you are getting. It could end up handling (more) like a truck or be so steep as to chuck you on yer earhole at the first roundabout. I note that in most articles about 'custom builds' of K bikes, the handling of the bike, while possibly a nice looking profile in glossy magazine or online piccies as compared to stock, is rarely if ever mentioned.
