Thanks for the info. Between the Duke Forum and RC Forum I should get plenty of ideas setting up the fork. With my other bikes, I would start at stock fluid spec then change from there. Increasing viscosity to increase compression and rebound. Increasing fluid height to add "spring rate" at the end of fork travel (by reducing air volume in top of fork). If that doesn't do enough, then Gold Valves (or YSS PD valve) allow a large range of tuning choices. I also have a 97 Ducati SS, and a 2014 Honda Grom, both with Racetech Gold Valves,and Racetech springs. The Grom fork is quite similar to the Duke, with its spring located under the valve,in the lower fork tube. A lot of work to change springs, and preload spacers, but hopefully it won't come to that on the Duke. Sorry I took a while to respond, but here in the Midwest, temps are single digits, blowing snow,etc, shoveling snow comes before the bikes, I hate to say.
