Troop, yeah my 0.8 springs are also not progressive. I checked the RaceTech site and they recommend 0.9 spring for my weight which will probably make the bike rigid :) I also checked the part numbers for older Tigers with Showa forks and WP forks and both list the same type of springs so I assume that the springs off my old Tiger will fit no problem in the thinner legged WPd Tiger. Still not sure about 0.8 spring. I actually like road feel. It improved steering tremendously but off road it was just too uncomfortable on long rides.
