Bad Surging On Freeway A Medium And Faster Speeds

[Trevor G]

My wife uses the 2015 F3-S most of the time and she said she hadn't noticed anything before.

Today I found after 15 minutes of riding that it would start to surge badly at 75mph and when we (traffic) slowed to 55mph it was still there.

After a 20 minute break it was OK again for 10 minutes before it came on again.

4900 miles - any suggestions from experience? It was so bad I thought the engine would eventually cut out.

Were you on cruise control?

Here in Kansas, traveling on the interstate among the rolling Flint Hills, the sudden wind changes can make it seem like the bike is changing acceleration. So what was the terrain like?

Yes, but it doesn't make any difference, I checked.

We'll get buffeting at 65mph+ on the freeways here because of the traffic density, but this was not that.
