We have genuine Suzuki OEM gaskets for the Magneto Cover of your Suzuki DR650.
 
If you need to fix or check anything on that side, this gasket can be easily damaged when you remove the magneto cover.
 
You can be either lucky and could remove the cover without tearing it apart or unlucky, and you will need to remove the old gasket and install a new one.
 
So it's a good idea to have a gasket handy before removing the cover, just in case you are unlucky with it!
