Flat tires never happen at a good time or location. Motorcycles don’t carry a spare, flat-fix kits can be problematic, and when we finally do patch the tube or plug the tubeless tire, we still need a means to re-inflate it. CO2 cartridges are compact but unwieldy, and a good supply of them is necessary to fully inflate a tire.
For the latter situation, Dynaplug (which also makes plug and patch kits) has introduced its Micro Pro Inflator. Ensconced in a zippered, nylon case that measures 6 inches long, 4.5 high and 3 wide, the pump weighs just 7 ounces and has a 20-inch coiled hose and a pencil-type tire gauge. Four pigtails are provided in the pouch as a means of attaching the 12-volt Inflator to a bike’s battery. Each has an SAE connector at one end that plugs into the Inflator’s 8-foot power cord, while on the other end these cords have alligator clips, or ring terminals, or an SAE connector (in case you already have a pigtail attached to your battery to accommodate a charger or electric clothing), or a plug for a standard 12-volt accessory outlet. Remove the red cap on the latter and it fits into a DIN (European)-sized receptacle. The alligator and ring terminal cables have a 15-amp fuse inline, but the other two are not fused, relying upon the one that should already be in place for your bike’s accessory outlet or charging cord.
To test the unit, I put my personal bike on its centerstand and totally deflated its 160/60-18 rear tire, then attached the SAE cord with the appropriate battery connector to the Inflator and my battery. With one end of the flexible hose now screwed onto the Inflator and other onto the tire’s Schrader valve, I hit the button on top and let ‘er rip. The unit sprang into action with a fairly loud, frantic air-compressor putter.
The unit draws 4.5 amps at 40 psi, inflates up to 100 psi and will run for 30 minutes before needing a 20-minute cool down. A very handy feature of the Micro is a second Schrader valve located on its base that allows the operator to check the pressure with a gauge while the tire is being inflated. I took periodic readings with the pencil gauge and found that the tire had reached 20 psi by five minutes, 30 at seven minutes, and in nine minutes reached my target pressure of 38 psi.
The Micro Pro with its hookups now resides in my tank bag as a permanent part of my gear. After all, if one bike’s battery were not sufficient to inflate the tire, other bikes may be available. The Dynaplug Micro Pro Inflator is designed in the U.S., manufactured in China and sells for $59.99.
