Very easy to use. I can park my bike and leave the mount in-place now with no fear of it being stolen.
Easy to swap over from the original RAM thumb nut to the new security knob. It does not add a huge amount of bulk but be aware that you have to leave sufficient clearance to use the key which has a reasonable girth (63mm including securing loop). Once fitted, you have just made your valuable RAM mounts harder to steal. I have 4 security knobs fitted to my BMW R1200GS Adventure and feel confident that all my RAM mounts will still be there when I return to the bike. Obviously, don’t leave your gadgets unattended as they can still be stolen. Well worth the investment and way cheaper than replacing stolen mounts.
I originally ordered a couple of Pin Lock Knobs for my motorcycle mirrors. I didn’t realise they would have different lock configurations. When I raised the issue with Max from Modest Mounts he advised how I could order Pin Lock Knobs all keyed the same. The return process for the original knobs was easy and the new Pin Lock Knobs - keyed alike- arrived super fast!
