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

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.

Good value, works, easy to install

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).

perfect kit for a motorcycle, compact, and easy to mount

Took care of overheating by losing coolant fluid.

Had trouble finding a place fpr it on my 2007 YZ450F. Once I settled on behind the radiator and tested things, worked great! No more loosing lots of coolant in tight trails..

Works as advertised. Smaller than the stock recovery tank but large enough to actually do something. You will need a 1/8" drill bit to drill a hole in whichever nipple you decide to use so keep that in mind. This would have been a five star product except it initially had a slow leak that drove me crazy. Turns out the seam between the two halves needed to be shaved down with a razor. No more leaks now after ~1000 miles.

Loved the size and mounting holes in the bottle. Very easy to install. I put it on an old 93 CR250. Attached to the radiator guards off to the side. Have yet to test it but looks like it will work just fine.
