STR8 Oversize Cooling Fan (alternator side) for air-cooled tuned / racing engines. When it is really warm outside, insufficient air flow can lead to overheating and subsequent severe engine damage (piston seizure) in air-cooled engines. Replacing the original fan with an oversize model with larger blades will increase air flow and help keep engine temperature at an operable level.

For air-cooled Minarelli horizontal engines, available in several colours.

Colour: chrome.
