Reservoir Sock?
 

Why do people use them? What are they for?

Why do people on the street use them?

lol, this is going to be fun, we argue about this every year.

There are a variety of reasons people believe this trend started, but no one knows the real "for sure" reason. It's pretty that's for sure.

It adds .03 hp!!! I use them because I like the way it looks. I have a CF res cover as well.

:lmao:

Didn't mean to cause an argument....was just curious. :lol:

The reasons I can remember right now that I have seen

Sunlight damages the fluid

It protects against small leaks on the track

fashion

keep the fluid warm once it heats up

Don't know about the other three but the first one's bullshit. I did a little search and saw some crazy reasons too!

My understanding was that it was to soak up the fluid in the event of the resevoir getting cracked, but that's mainly for track use. No clue why people use them on the street, other than to look cool. It's not like it takes much effort to remove it for street use and put it back on for the track. Unless people are just worried they'll forget to put it on when they take their street bike to the track. :idk:

A quick google search shows a lot of boards (including gixxer.com and r6-forum.com) pushing the UV damage excuse, so that would explain why a lot people believe they use it on the street.

The sunlight thing is what I had always heard.

If that were truly the case the reservoirs wouldn't be translucent. :idk:
