Head shaking...

OK, this is a weird one. I have a bit of a head shake between 25mph and 50mph. When I let go of the handlebars, the head shakes almost to the stage where a tank slapper could be imminent. Before and after, it is perfectly smooth, even when I take my hands off the bars at 80mph.

This is a CB1300, clean history, almost all the history is there, last two services done by a main Honda dealer.

Anyone experienced this? Is this just a CB1300 thing?

get wheel balancing checked

Also might be worth checking to see if the head bearings are ok.

I had a similar problem, turned out to be the tyre (irritatingly there was also plenty of tread left, but something failed in the tyre's structure) - new tyre fixed it.
The advice I had was to check tyre, head bearings and wheel balance.

I've literally just had this issue resolved. Mine was a missing engine mounting bolt. I've been dealing with it for about 2months. Whenever I let go of the handlebars it wobbles, then it gets worse and worse. First time I saw it happen that apparent I almost let it bang from side to side because I was in utter disbelief at how bad it had got.

I also found it was very very wobbly at Motorway Speeds. But yes, check your mounting points.

Had exactly the same problem on my CBR600.
First thing I checked was the head bearings, didn't need to look any further than the castle nut, it wasn't even finger tight! Shocked

Nipped it up and that cured the problem.
