that fork was oem on my '99 KK. nominally 75mm, actually more like 70. was it used as early as yours also?
edit...sorry. scratch that. oem in '99 was the marz superfly. kona site archives only go back to '97, when the Z1 was in fact oem.
Yep, while the Z1 was shown as the OEM fork for 97, the Z2 was also optional.
For 98 the standard fork was the Z2 BAM and for 99 the Z2 superfly in custom orange to match the front of the frame (red Z2 BAM for the 99 Hei Hei). I'd love to find a 99 Hei Hei or King Kahuna to build up because the paint on the front makes it that little bit different.
Interestingly I've not seen any article or photo of a 97 King Kahuna (other than mine) with a Z1 Bomber on it, and the only 97 Hei Hei's that I know of which came as complete bikes had Z2's fitted. I can only assume that the 100mm 'DH' Z1 was considered too long by many riders, whereas it seems the perfect length now
