The Trekker Outback are cases studied especially for the off-road use. For supporting all the demands that are subject in off road, they need fitting systems and side-case holders stronger than the Monokey®. For this reason it has been studied that the new Monokey® Cam- Side system, fixes the case in four different points maintaining at the same time the possibility to release from the rack quickly. The specific side-case holders are manufactured using steeltubular with an 18 mm diameter, and are fixed to the bike in different points, in order to strengthen the structure. Besides the panel of the frame where the case is linked, it is better if the rubber supports points are moved in the perimetric zones of the case.
