If you know Hugh’s HandBuilt, then you know we don’t offer ANYTHING to the public that we don’t fully test ourselves.  This new oil cooler is keeping with that tradition, having been 2 years in the making.

We have the largest surface area of any Bolt-On oil cooler on the market, while increasing oil capacity by 120cc’s.  More oil and more cooling surface = Cooler Running XS650 Engine!

You and I both know these bikes were built in a time of 55mph speed limits…  Who’s doing that speed now?  Not me…  Keep her cool, while blasting the highway!

We’ve tested various filter combinations, checking for oil pressure losses and restriction, and found the OEM style filter works best with the XS650 Oil Pump to keep flow and pressure at a maximum.

Hugh’s HandBuilt Tested and APPROVED!
