When using my throttle friction lock, I've noticed a handlebar wobble at 60 kph , not there at 40, 50 70, ,80 or 110 kph (our various speed limits - school zone, builtup area,  etc). This is when i've taken my hands off the handlebars. I put my hands back before it goes to a tankslapper. Sometimes I have to take my gloves off to relieve carpal tunnel pain or adjust a flapping helmet strap. Tyre pressures are correct. Swing arm bearings replaced 10,000 k ago.

I'm thinking, in order of ease/cost
1 - jack the front wheel up and check free play
2 - remove front wheel and have wheel balance check done
3 - check/replace steering head bearings

What are the symptoms for worn steering bearings ?  Do they start at just one speed ??? Any other suggestions.  Thanks  :-\

i had a similar problem at 60-80kph...checked all the things you've listed.
i had the wheels trued and the wobble disappeared...however it felt like i was riding a horse. ended up changing the tires to bridgestone (from michelin commander II's) and viola problem gone.

hope you find it!

what kind of tire do you have? I had a similar issue with both my W-650 and my 1500 Drifter at the same speed. I replaced the front tire on the W from a Metzeler ME-33 to a Continental Conti attack and the problem disappeared. I replaced the worn out Michelin Commander on the Drifter with a Metzeler ME888 and the problem disappeared, as well.
