  • Tusk Radiator Hose Kit

    Tusk Radiator Hose Kit

    Tusk radiator hoses

    Bought these red hoses for my 17 crf450 just for a color change. They fit perfect, look great and are top quality. Why pay more for a name that does no better than Tusk. I have never been disappointed with a Tusk purchase.

  • Boyesen Supercooler Water Pump Cover and Impeller Kit

    Boyesen Supercooler Water Pump Cover and Impeller Kit

    Scott in NC

    Solid product but mostly for looks

    The boysen cooler is a great looking addition to your bike. As far as performance it has a slightly bulkier impeller which claims to increase cooling efficiency by up to 5% under EXTREME conditions. I would say 90% of the people buying this product will only benefit from the looks of it. I am one of those people and this is the second one I've bought for my bikes.

  • Tusk High Pressure Radiator Cap with Temperature Gauge

    Tusk High Pressure Radiator Cap with Temperature Gauge


    So far so good. Used on an older YZ coupled with new higher pressure hoses to hold down the temp. Works well.

  • Motion Pro Coolant Recovery Tank

    Motion Pro Coolant Recovery Tank

    Terry in MO

    Just a little peace of mind.

    Wasn't for sure where I was going to mount it. But I definitely think all enduro type bikes should come with this as O.E.M equipped. I knew it was going to be behind the front # plate are in the air box. But I was not sure of the size of it when I purchased it. And I really wasn't wanting to put it in the air box. But on my bike luckily it fit perfect behind front # plate. This is just me personally. I run Engine Ice coolant and at its price. I'm not crazy about it boiling over with nothing but the ground to catch it!!!
