ONE issue w/ DRZ forks - they have MORE travel than the V has ground-clearance, so IF you don't RAISE your bike, you might hit the ground w/ your engine/ skid-plate on a serious 'whoop'....
having run both the 130/80 rears up front and the typical 110/80-19 on the 19" cast wheel with the stock Versys suspension, there will absolutely be interference with the lower fork clamp and fender if the fender is raised enough to avoid trapping mud. interference will happen even sooner if the brake line guide is left in place. pull the tape, do the math, the result is inevitable given the right conditions for a full stuff of the forks. the event can happen both on and off pavement, and can be very inconvenient depending on speed and road conditions. whether the event is important to the rider or not, it's their bike, their call. the stock Versys forks have been extended, with the writeup posted to the forum, a worthwhile mod if running OEM forks with a larger diameter front wheel/tire.
as far DRZ fork travel allowing the Versys skid plate to touch down on a "whoop", this time pull the tape and deploy the trig based on the new ground clearance with this swap and a 25d rake...that statement is complete nonsense.
DRZ fork right, Versys fork left. The DRZ forks are used with the Versys clamps, a 20mm projection at the top clamp is typical. nothing on the bike touches the ground on whoops except the tires. ride the same whoops at the same speed on a stock suspended Versys, you're going to break something.
Kawasaki Versys with 17/19 wheels, big suspension, and a bunch of other stuff. the skid is stock Motech, the same one everyone else uses. i have seen a scratch or two on the bottom of the skid, but infrequently, with no dents or other damage. The sidestand is KLR650 that has been extended 85mm over the OEM length, just to give an idea as to how this bike's stance differs from the stock Versys. the LV can has never received any damage in that location, despite traversing some very tough road conditions.
