Preload Adjuster Motor Failure?

Post by Terry Shiels » Sun Dec 06, 2020 11:13 am

I had my 2016 stall out a few weeks ago. When I cranked it back up the screen was blank. A few minutes later I filled up with gas. Screen came back to life, but with a new error message... "Preload Adjuster!" Took it to the dealer when the error message did not go away and the corresponding suspension adjustments were not operating. Bad news from the dealer... "the bike is going to need the shock preload adjustment motor... the part is $711.00." Then labor, of course to install. Anyone else have a failure like this? I love the sophistication of the electronics on this machine but I am out of warranty now with 34,000+ miles on the bike and wonder if I should be prepared for more expensive repairs down the line?

That sucks. It is a worry on anything we own "out of warranty". I am on my 3rd KTM street bike, 2014 SDR, 2016 GT and presently 2019 GT. I have had zero problems so far with all of them. All manufacturers will have problems. Some more than others. You have a quality bike and hopefully that is all the problems you have. You know what they say, "you want to play, you have to pay". Lol

I had the same problem with my 2017 Super Duke (29400 miles). Stalled the bike and when restarted it, I got the Preload Adjuster warning and the preload setting would not change. The dealer 127 miles away was able to reset it with the KTM diagnostic tool. 4 days later after I rode home, the 1st time I tried to change preload I got same problems! Were you able to fix the problem or was it necessary to get a new adjuster motor?

When you adjust, change suspension modes, make sure you take your body weight off the bike. Seems the motor isn't designed to load and unload the spring with body weight aboard. And having a passenger aboard would even make it worse. So do all spring preload adjustments with your weight on your feet and no passenger aboard.
