Power Sports Tech has developed an engine cover that helps keeps snow off the engine and keeps engine temps up especially for cold powder riding days . The cover also folds down in stages so you can adjust venting for riding on packed snow or warm days. The cover is made from a light weight nearly indestructible material and can be taken off in minutes or worn all winter season. Each cover has been custom made to fit the specific bike model. We have found that with the combination of a ventable engine cover, thermostat, and a water temp gauge you can keep engine temps in the safe range. Engines run better with less over fueling from the computer reading cold engine mode.
