I bought this pump for my two Yamaha’s and now my ktm. I would highly recommend this product to anyone. It definitely helps out here in the hot summers we have in the Carolinas.

So it’s not really clear what models come with gaskets and which ones do not. I ordered this kit for my 2017 yz450f the kit came with the pump cover gasket. Unfortunately you have to remove the right side case cover and replace the impeller shaft. So be sure you order the supplies for an oil change and the case gasket with this pump.
Pretty good stuff
Supercooler is just that, consistent 8 degree temperature drops over stock in 95 degree Florida heat!! Worst part of installation is draining the coolant, other then that 5 minutes later Braaap!!!
purchased this product for my 2009 crf450r so it would have better flow and less cavitation. the product does what its advertised to do, I can certainly say the bike runs a lot cooler with a fatter radiator especially in sunny Yuma AZ.
My crf450r was having trouble staying cool, so I purchased this item. It only took 15 minutes to install, great product my bike runs a lot cooler after installing the boyesen supercooler. Definitely recommend buying this item.
You hear a lot of rumors about aftermarket pumps but this one is the one. It really works. When compared with the stock impeller this one is significantly larger. My 07 CRF250r used to run at like a billion degrees but now it runs smoother and cooler. Buy this it's worth it.
Received my order in time for a weekend of trail riding in which this supercooler shines! Very easy to install..10 mins max! Does what it says. The impeller has larger fins to move coolant more rapidly. Great add-on if your bike gets hot!
I ride and race enduros and my bike runs a lot cooler and doesn't boil over anymore
Threw the Boysesen super on my yzf250 last week. Install was super easy and it looks great on my bike. Contrary to other reviews my kit came with a gasket. I would have given it 5 star except it doesn't look like the picture. Although mine was for an 02 yzf250. Newer models may differ. Motorsport rocks!! Customer for life!!
I'm not a mechanic,but, with the ease and simplicity of the destructions, the super cooler went on without any problems!!! Haven't been ride'n yet but it sure looks cool and hopefully will keep my bike just as cool...
The water pump and impeller installed super easy on my 08 Honda 250F, it was about a 5 minute job and I also went with engine ice for coolant, bike seems happier now and running cooler, so I am set for tight single track woods riding where overheating for me was more of an issue.
I bought the super cooler for my 2004 yfz 450 that has been bored to a 478. The bigger bore has made it run a lot hotter but thanks to the supercooler, my yfz stays at a much lower temp now! Again, GREAT PRODUCT!!!!
I installed on an 08 honda crf250r. It is very easy to install and it does look a little bigger than the stock one. I gave it 3 stars because of cost, it didn't come with a new gasket, and I cant tell that much of a difference but it does look good.
I bought this after having over heating problems at the snowshoe GNCC. Bike ran cool in the 100 degree temps at the John Penton after the install!
just installed the hot rods stroker kit in my 04 honda 450r, running on 112 octane this thing brought my temps way down! amazing would buy it again!!
I do a lot of desert riding (Glamis) and my engine temps would get a little high after hard riding out in the dunes, but after I installed this I did notice a decrease in temp. The impeller is noticably larger and no issues to date. This was placed on a 2009 yz450f. I will be getting this for the next bike I own, what ever it may be.
If you're tough on your bike and you do alot of single track and race offroad, this is a must have product. Bought this a couple of years ago for my Honda crf450r cause I had a couple of boil-overs. Ever since I bought this product, I haven't had any problems with over heating my bike. A great product, easy to install and looks great.
this product is amazing my 04 yfz 450 runs so much cooler for being in the desert. I can't wait to get one on my wifes bike.
This product is awsome easy install and bike runs much cooler thanks
