Anyone who is seriously interested in motorcycles knows that they need the best quality brake fluids for their safety. Unfortunately, these quality brake fluids are very sensitive to UV light. To keep the fluid safe from the environment, they usually put a sock on the reservoir cap to prevent UV rays from causing damage to the brake fluid.

Since there are many debates on the topic of brake fluid degradation by ultraviolet rays from the sun, perhaps we can add that looking at MSDS (material safety data sheets) indicates that brake fluid should be stored Away from sunlight, this is also the reason why they are not sold in clear bottles, but the clutch fluid reservoirs of most sports bikes are opaque, allowing sun / UV rays to reach to brake fluid, thinking that aesthetically they will also cover the ugly plastic deposits of the brake and clutch.

Reservoir sock covers also help prevent brake or clutch reservoir spills or leaks. These are basically designed as wristbands that wrap around the brake and clutch reservoirs to absorb any fluid that may spill or seep through the cap of the brake and clutch fluid reservoirs, such as in cases of hard braking. And yes, brake fluid does expand and anyone who’s really tough on their brakes will know it. The danger is that the highly corrosive fluid can damage paint, metal, and get into riding gear like the visor, which could cause real visibility problems. For those who are into motorcycle racing, the tank covers will also keep the tank covers firmly in place during a race and / or spirited riding. It can also help keep your brake fluid from getting dust or dirt by keeping brake / clutch fluid reservoirs clean and away from debris.

Many brake reservoir fluid sock covers are made of cotton and constructed in such a way that each of the socks fits properly, as you don’t want them to fly off the road or track. When it comes to clutch fluids, it’s basically the same principle. Brake and clutch fluid reservoir sock covers prevent fluid from degrading to the environment, which can eventually lead to poor braking and shifting performance. And since most of those who use these tires are involved in motorcycle racing, poor braking and shifting performance and bike brake fluid spillage would be of no help on the track.

For those wondering if they could just buy generic bracelets for their brake or clutch fluids, they can, at their own risk. But bracelets tend to be too loose and will eventually fly off the road or track. Obviously, bike fans would probably be horrified if they saw their precious Honda, Yamaha or Ducati motorcycles dressed in poor quality products that did not fit well. They would want to get matching Yamaha tank sock covers for their Yamaha and Ducati, rather than have a poorly fitted wristband with a sports shoe brand covering their brake and clutch reservoirs.

Many of these motorcycle brake and clutch covers can be purchased online or at reputable motorcycle stores. They are relatively affordable; Generics are particularly cheaper but of lower quality and have hot-pressed logos that tend to peel off after a few months. Higher quality tank sock covers will be made from high quality cotton, specifically made to fit your motorcycle application and will have matching logos that are embroidered.
