As the title suggests, are brake fluid resevoir covers worth the small investment? I was told by a buddy that sunlight on the fluid was not good for it and would cause for premature fluid change need....any ideas or knowledge is appreciated!

I had a ninja turtle sweat band on mine from the previous owner. I thought it was tacky but I never took it off haha. I like the ninja turtles anyways...

Someone stole it one day though right off the bike... I've never covered the reservoir since...

While UV light may have a bad effect on brake fluid, it's not a concern you need to be worried about if you change your brake fluid as often as you should.

I go every other year on the street bike and twice/year on the race bikes.

The res. is very opaque to begin with, there's not much light getting through there in the first place. If there is fluid leaking out of res., you have a serious problem, fix it, and not with just a wrist-band to soak it up. I'd assume that either means you have a leak (VERY BAD), or have over-filled it (VERY BAD).

It does add a personal touch to your bike, and for that, it's very cool :)

I think they look retarded, but to each their own Those things are meant for your arm/wrist. And they don't actually serve any real purpose unless you store your bike outside 24/7 in direct sunlight. By the time the sun has a chance to do any real damage to the brake fluid, you should be changing it anyways :O

The fluid is something you should look at. Every time you get on the bike. It's your brakes fer chrissakes.

I consider something that makes doing a simple check (very slightly) more difficult as an added complication.

Oh, you young whippersnappers.
I can't remember what year it was. They originated out of necessity. Dunlops RC30 developed a leak in the reservoir cap due to over pressurization from heat expansion. Since there was no threat to the hydraulic pressure in the system (reservoirs are relatively neutral pressure) the quick fix was a sweatband. I think it was a blue one. It was not a HRC sweatband as is often reported.
Note to ya'll though: If you think it's a good thing to have a full reservoir on the track, you'd be wrong. Twice in just the last year I have had to remove fluid from TD guys (one girl actually) reservoir because it was too full. Halfway through the session brake fluid expanded enough due to heat that it pressurized the reservoir. Then the brakes began to drag, then they overheated, then they faded. Just keep it between Min and Max. :D
