The Viair 85P is a portable compressor with a built-in LED work light and gauge. It weighs in at a paltry 4 pounds and is only 9.1 x 3.1 x 5.6 inches so it can easily fit in a saddlebag with room to spare. We have used the 85P to inflate any size motorcycle tire by simply screwing on the solid brass tire chuck to the low tire’s valve stem and plugging the 10-foot ling power cord into a 12-volt (cigarette lighter) power port. With the misfortunes I have had with tires losing air lately I have found the 85P is quality made, works very well, and has become an indispensable part of my motorcycle’s tool kit.
