Motion Pro(11-0099) 275cc Coolant Recovery Tank - 9.3 oz. Capacity

Works great. I went with option two for hose routing so that way the system always has coolant and no air in it.

Took care of overheating by losing coolant fluid.

Put it on a 06 KTM 450xc that likes to puke a little here and there and this saves me big time as well as a working fan.

I ride in the heat in the woods and have these on all my bikes. If you do this right once the bike pukes and then cools down it will suck it back in the radiator. Keeping the level right.Funny, my son told me he did not need this unless he was riding with me. If you are a dirtbiker you know what he means. He is 30 years younger.......lol.

I like how they provide an option to fill from the bottom/overflow from top or fill from top/overflow from top. My bike doesn't barf coolant anymore on trail rides or 2 seconds of idling, so that's a big win. My bike is now dirtied by a Yamaha blue color so I may need to change to an orange-ish coolant (j/k).

Good value, works, easy to install

keeps the antifreeze in my bike

This is a no-brainer buy. For ~$22, the quality, materials and fitment are very well worth it. I highly recommend you hit Buy Now and stop reading any further, but if you must...Super easy to mount with flexibility on how you mount it. Zip tied mine to the side of the radiator after making sure everything would clear and routed the hoses exactly how I needed them. They give you more than enough hose (1-piece) to give you great placement and routing without any bends. 12/10. Highly Recommend.
