I bought the Accutire MS-4021B air gauge for my car and truck because it was highly rated by Consumer Reports. It's a great and accurate gauge but it doesn't work well on my Like 200i's rear tire. Thanks for the advice on the model MS-4710B for motorcycles.
As a side note, I am about ready to order a Genuine Innovations part number G3518 for emergency tire repair inflation with CO2 cylinders. It comes with a repair kit, flexible hose, three 16 g cylinders and a carrying case.
