RAM Mount replacement bracket for the Garmin zumo motorcycle sat navs If you have a number of motorcycles, or if you share your zumo with friends, you can get on the road more quickly with your Garmin zumo if you give each motorcycle its own mounting set. Then a twist of the wingnut is all you need to exchange your zumo together with its mounting cradle, upper base plate and upper ball head. The base plate, which consists of a set of steel shackles or of a mounting holder, and which is mounted directly to the clutch and brake lever unit, provides extremely robust attachment for your RAM Mount. Fits all 22 mm and 25,4mm (inch) tubular handlebars. These high-quality, long-lasting products are made of aluminium, and incorporate a vibration-damping rubber ball.
