My son Scott raced his '13 300e to 5th place in open class at our national enduro last saturday He complained of the rough track and sore lower back and kidneys, So today went out to observe suspension behavior, the bike has sachs rear and 48mm cc forks.
Noticed that when riding straight into,no pre-loading or bunnyhopping, a 20cm high square edge rock in 3rd /4th gear, the rear would bounce up about 1m into the air, pretty eye opening. The hs comp was 8 clicks out, comp 10 and rebound 10. I adjusted the hs comp all the way out 22 clicks to observe the diffs, and attacked the same rock same speed. Guess what, the rear only kicked up about 50cm, wow! . But now the shock felt solid while sitting and bouncing up and down, like the rebound was now way too slow. Adjusted the rebound to 15 clicks out and voila, looked and felt good. Then adjusted hs comp back to 15 clicks out. Now he could actually hit the rock even faster and safer, the poor rims and mousses. So perhaps you could look at slackening of the hs comp on the Ohlins too
