High Speed Wobble

Post by RoadWarrior » Sun Jun 03, 2018 10:29 am

Noticed this weekend a slight high speed wobble at around the theoretical 80 mph (~130-135 kph). I have changed new tires this year, new wheel bearings, new shock bushings. Brakes were serviced (when the tires were off). Trying to figure out what else could cause this?

Stem bearings?
Fairing mount?

What else that I haven't thought of? Any ideas

First thing I would check is the front axle pinch bolts.
Seems to have been a common cause of wobble, as you have to tighten one side , then bounce the front a couple of times to make sure the axle lines up straight.Then tighten the other side, then re-check the first set.
Also re-check the axle bolt is good and tight ! (speaking from experience :doh: )

Thanks, good recommendation. When I put the front tire on (while on the stand), I tightened the pinch bolts then took the bike off the stand. I did not bounce the front end, then tightened the pinch bolts. I just went to the garage and loosened all the pinch bolts, bounced the front end a few times and noticed the axle moved inwards a bit. I then tightened the pinch bolts.

I will take it out for a spin and let you know if there is improvement.
