This snow machine cover provides year round indoor and outdoor protection for the YAMAHA VK 540 156 2018 2019 model years. Keep salt, slush, mud or other elements off your snow mobile. Designed for summer storage as well as winter travel purposes. Cover is water resistant to permit air circulation and is woven tightly enough that the surface tension of water or ice melt will not penetrate, it will roll right off. Enjoy your next snowmobiling cross-country/backcountry sled trip with a like-new vehicle and clean dry seat every time. Cover comes with a free stuff sack so you can take your snowmobile cover to the winter camp with you, or even ice fishing with your crew! Packs small. Will not scratch clear-coat. The elastic bungee in the hemline holds the cover snug to the chassis/track for a secure fit. Metal hook straps keep the cover secure. Two air vents allow excess air to escape without parachuting and the bright rear reflector strips help ensure that your sled is clearly visible at night or while trailering home at the end of a long day on the back country trail. This semi-custom cover will fit the sled indicated. We make many covers compatible with arctic cat, polaris, yamaha, skidoo bombardier and more. Our semi-custom cover designs are compatible with most snowmoble on the market. IMPORTANT: This item will only fit the sled specified.
