916 Belt Change

This type of spanner works if you really want to torque the nut (bearing in mind the correct orientation with a torque spanner), but i normally just do it by hand.
And I always fit new lock nuts

 

That's a very clean looking bike there.

 

What is that actually called? I can see it's a derivative of a crowsfoot, but does it have any particular name?

Thanks

 

Crowsfoot ring spanner i think.
Google Laser 7286
