AT LAST - the days of sacrificing sleek lines and design style in the name of keeping oil temps cooler are gone. The new Oil Bud ™ intercooler efficiently delivers a 35 degree oil cooling differential, but what's better, the under-mount design means no one knows the Oil Bud ™ motorcycle oil cooler is on board.

Perhaps the reluctance to bolt the traditional radiator style oil cooler to the downtube or the front of the frame has left some Harley owners in denial about the importance of oil temperature. Bud Clarke, owner of Bud's Biker Parts, wasn't content to let oil temps on his 2005 Harley Softtail run at 250 degrees (newer Harleys up to 280 degrees) and risk engine trouble.

One day when walking by an experimental airplane he was building at his business - AirRyder - a thought struck Clarke. If the oil cooler he designed for this turbo charged intercooled airplane could cool oil temps from 260 degrees to under 200, certainly he could design something for his Softail Harley.

And he did.

Inspired by aircraft technology, the Oil Bud ™ oil cooler is built from aircraft quality materials, braided stainless hoses and 6061-T6 aluminum extrusion and welded in header tank assembly. The temperature regulator starts to open when oil temps hit 185 degrees and fully opens at 200 degrees. Temperature differentials from the cold to the hot side of the cooler have been measured at more than 35 degrees.

The durable Oil Bud ™ oil cooler fits between the frame rails of your Harley, and once mounted under the motorcycle, it is virtually undetectable. It is designed for 2000-2011 model years Harley Softail, 1999-2011 Harley Touring and 1999-2011 Harley Dyna. It is easily installed with no major retrofits required. Cooler oil temperatures mean longer engine life for your motorcycle. What are the costs to your engine when oil gets too hot and breaks down? With Oil Bud ™, Harley Davidson owners no longer have to take the chance of running hot oil temps .
