Brake Fluid Reservoir Cover Sock for Motorcycles, Sporbikes and Gifts by Moto Loot (Yammy)

fits perf and it adds a cute touch to my yamaha

great materials, looks great on the r7.

It is what it is. A snug fitting cover. If this is your thing then this is a great item.

Let's be honest, this is really just a wrist sweatband. It's supposed to go around your mastercyclinder for protection and leak absorption. And I think for that purpose it is fine. Unfortunately it is too big for my particular bikes configuration, but as I said... it's really just a sweatband so that's what I'll use it for. You can also use that as a guide for sizing. If you think a wristband would fit on yours this will work, and really it's about the height of the item, btw.I will say it is made from nice terry cloth material and the stitching is good.

Put this on my yzf600's brake fluid reservoir and it fits like a glove. Totally pointless but it's fun to add some swag to the bike. Well made and durable.

At certain angles it looks like it spells TAMMY

I don't know what the point of this thig is, but it's not exactly a reservoir cover. It's more of a wrist sweatband. You CAN put it around your reservoir, and I did just that to my XT... but I'm not exactly sure why I did.
