I'm sorry, but the above mention of 'thick twat' is a bit over the top.
Before I bought a R12GS, I'd never ridden with handguards.
In 2005, the front wheel of my new heavily charged R12GS skidded on gravel, while braking. I'd never ridden with power assisted brakes before, and the bite of these brakes is something you have to get used to. I don't think anyone will argue this.
Anyway, the rightside handguard turned as it hit the ground, and the brakelever was forced back due to contact with the handguard.
When restarting, the ABS warninglight came on, and there was no way I could move the bike. I searched for quite a while to find the cause. I finally rang the dealer who told me WITHOUT THINKING TWICE that I should check the handguards. Problem solved.
Quite frankly, I think I was lucky that the brakes were jammed completely, preventing any riding. I dread to think what might have happened if the brakes were just 'slipping'. As a reminder : someone has died as a consequence of these handguards.
My personal opinion is that the R12GS is riddled with design- and engineering flaws (batteries, rear axes, gear boxes, brake disks, handguards, servopumps, ringantennae, pumpcontrollers, corrosion, gearindicators, fuellevel indicator, faulty software upgrades, loose topcases, and there's more), and that BMW takes forever to remedy. To my surprise the facelifted model is no improvement (brakes, pumpcontroller).
I have to add that it's a dream to ride.
