STR8 Oversize Flywheel Fan

Using a scooters original air fan, with its relatively small fins, during the summer months or with highly tuned air-cooled engines, can result in adequate air flow causing piston seizure. A solution to this problem is to replace the original fan with the STR8 oversize fan; with its larger fins it produces much better cooling. The STR8 oversize fan is available in a choice of colors.
