But I believe that the front wheel on the triples is a 1.60 X 18 share as the front wheel on the KZ is a 1.85 X 19. They both cam with 3.25 wide tires. I think the wider rim might fit the tire better? That's why I suggested the Rear Wheel off the KH400 triple since it's a 1.85. It does lace to a drum so maybe the angle of the spoke coming out of the wheel would be different? Anyway you look at it, a set of custom spokes would have to made at least using the rear KH wheel. I don't know about the front if you could use the stock front spokes off the KH. Maybe the disc brake hub is different than the KZ?
