The screw-on caps of the front brake fluid reservoirs are、 of course、 fitted at the factory with a safety mechanism but because of their exposed position and because the caps are so handy they are very often messed about with and turned. Therefore、 after a relatively short time it is possible to unscrew the cap easily without tools. Our guard quite simply prevents this. The guard is screwed on and off quickly and the cap can no longer be grabbed easily. The whole reservoir is also protected. Made of laser-cut、 anodised aluminium.
