My last ST1100 acted the same way, bounces 2-3 mph past about 65 mph, it's solid up to this speed. I did a search and found nothing, anyone know the cause or cure?
 
May be its the bikes way of saying go faster...:D


Seriously, have a look at the speedo drive on the front wheel, it may need a bit of grease to stabilise.
 
Only time I had a bounce the speedo cable wasn't correctly installed at the bottom end (speedo gear on the front axle).
 
This is a sign that the inner drive cable is binding and needs to be lubed. Ignoring it will eventually result in a broken cable. Disconnect the cable from the drive end at the front wheel and pull the inner cable out. Don't be surprised if it looks a little rusty. Clean and re-grease it with some good wheel bearing grease, just a light coat over its entire length and then reinsert it. If it's really rusty, removing and flushing out the outer cable jacket is probably a good idea as well. Should solve the problem.
 
If you find the cure, please post it. Mine has a wicked bounce as well. Lubing the connection on the fork, lubing the cable, hasn't made any difference... Kind of figured I had to live with it and forgot about it. 25K and it hasn't changed.
 
Jeff has the answer. If that doesn't fix it, I'd replace the cable and the outer sheath. It's not that expensive.
 
Remove and flush out the speedo drive with some brake cleaner, strip it down and inspect it.....

If all okay, pack with some bearing grease (Castrol LM will do) and refit.

Buy a Honda speedo cable and fit, having first pulled the inner out and applied a layer of LM grease to it. Ensure properly connected at the top and bottom and routed properly. This can be difficult especially on an ABS equipped bike.

If this doesn't cure it, your speedo itself is probably suspect......

Normally a speedo bounces around just before it stops doing anything at all.
 
Ok, I took the speedo cable off, pulled it out of the sheath and lubed it with moly grease (I had already lubed the speedo gear). Now the bounce is barely there - instead of bouncing a few mph it bounces more like one mph, more like a small vibration - only above 70 mph. I can live with that, thanks for the replies.
 
make sure the cable does not have a kink in it. Mine failed due to previous owner not takign care. I lube the cable every front tyre or so.
