A big wallet or serious skills.
COO, OTEC, Taylormade, and Billet Bike Bits are places that can assist. COO is the most cost effective IMO other than doing it youself or having patience to search and find a good deal on used stuff
If you are gonna do a complete front end swap with wheel and everything here is a brief overview of what is needed.
Triples to match your forks. If you buy them right, everything bolts right on.
Maybe fork extensions
Forks
Fender
Wheel
Calipers
Rotors
Custom brake lines
Misc new stuff like wheel bearings, seals, brake pads
Master cylinder
Most likely a speedometer as you wont be able to use the OEM mechanical drive
Paint/Powder/Chrome
Fork springs to match bike and rider weight. It WILL be undersprung
Should think about revalving to take full advantage of the new forks $$$
Or, buy a kit from COO or Taylormade. COO has many different options of wheel choices (any vmax wheel or sportbike wheel to match forks, vmax or sportbike fender,)
I've seen some setups where you just buy a custom lower triple and use the vmax stem and the sportbike upper triple. Cheaper that way. Not sure who sells those but they are, or were, out there. But, then you have issues with mounting the bars and stuff.
I think the OEM forks can work just fine if setup properly with emulators and good springs. I would say the biggest improvements you can make in handling would be properly setup OEM forks, radials, and a braced swingarm.
