1250 GSA handlebar clamps

[BigKev67]

I have just started fitting the wunderlich 40mm up and back bar risers.
I loosened the four clamp bolts and removed the clamps.
Then I decided to look at the instructions and realised that maybe my understanding of bar clamps was wrong.
I have always made sure that the gap at either side of the clamp was equal.
However that does not seem to be how these clamps work.
The instructions seem to indicate that one side of the clamp (the front) has zero gap and the tightening is done by the rear bolt that ends up with a gap.
I presume the front bolt can be done up firmly as the two faces are in contact, and the rear bolt is the one that applies the clamping force, leaving a gap.
I wish I had looked at the clamp gaps before I removed them !

Is this right ?

Correct, make sure you torque the bolts up, easy to overtighten

Hi BigKev76

Yep don't worry there is a little gap in the rear ones.

Thats interesting. It appears then that handlebar clamps are not all the same
The GSA system is a pinching system where one side of the clamp is fixed and the other closes down on the bar to secure it.
The equal gap system that I am familiar with is more of a vice like clamping action. I better go back and check my Honda CRF 250 rally and see if I have fitted those clamps correctly as I used equal gaps.

You have many questions relating to your new bike. This is a good thing in my opinion as part of the joy of owning is understanding what you have and how it works: what is within your abilities to fettle and what isn’t.
For about £65 Your dealer will supply a maintenance DVD which has a wealth of information with diagrams and torque settings etc.

Don’t believe the dealer if they tell you no such thing exists, it does, here is the part number.
