The bike is a Husqvarna SM610 (motard), weigh about 315lbs, rider weighs about 220 with gear. One track day at autobahn north a week ago. Rear shock was close to full stiff on comp & rebound. Bike felt good, but I softened comp 1 click (out of 4 or 5 total) and soften rebound quite a bit (4 from full soft, out of 22). Started at 24psi, dropped to 22. Bike still felt fine, but seems to move more after the changes. Ideas, suggestions?
I will answer only because no one else has and im sure u want some help. No expert but it looks like the edges are spinning and the lumpy stuff is suspension out of adjustment. My slicks started doing that but much worse and I was unable to ride the bike. I felt like I was on marbles when leaned over. The bike was sliding everywhere. I went back to power races and my lumpy wear went away. My bike suspension was set up profesionaly for power races. Hope this helps.
Check the hot pressure next time you run them and see if the pressure has jmped enough/too much Someone on here had a good tire pressure write up a bit ago - or on one of the forums I read hehe - anyway you might be running the rear at too low a start pressure for the weight on the tire, that will when cornering cause some shear across the tire surface (can give you that cheese grater look) - anywho my 2 cents worth or knowledge - might want to bug a suspension guy next track day
