Sub Frame Oil Cooler

Modern Triumph Bonneville and Thruxton engines are oil cooled as well as air cooled. As such they are fitted at the factory with a supplemental oil radiator of questionable looks.

Streetmaster ran tests to determine the efficiency of the factory oil cooler in comparison to running the oil through the tubing of a replacement sub frame. It was found that the sub frame cooled oil temperatures dropped at least 20˚ F more than the stock oil cooler. This was due to the large surface area of the tubing and an increase of oil capacity of almost 1 liter. The result is a much cleaner appearance and reduction in complexity.

The unit is a direct replacement and installs in less than 1 hour. Price is $849 - credit of $100 with returned OEM cradle assemblies.
