Y07J Engine Jacket

This jacket is for the 2010-2013 YAMAHA YZ450F.  It is unique as it’s the only bike without an exhaust pipe in front of the engine, so this jacket can fully encase the engine without the need for a secondary “Cold Weather Panel” – it’s essentially built-in.  I don’t have a picture of this jacket on a bike, so I’m still showing the conventional Yamaha jacket layout in the pictures.

Although the Thermo-Bob shuts off the radiators in the extreme cold of snow bike riding, the snow that gets on the cylinder and engine cases still acts as a “third radiator”, sucking heat out of the engine.  Power Sports Tech has developed engine jackets that helps keep snow off the engine and keeps engine temps up especially for cold powder riding days . The jacket also folds down in stages so you can adjust venting for riding on packed snow or warm days. It is made from a light weight nearly  indestructible material  and can be taken off in minutes or worn all winter season.  Each one as been custom made to fit the specific bike model.
