With the trail and dirt bikes in the Duro series, you are ready for real rock'n roll. Pump track, skate or dirt park and all the action on the trail and downhill - that's what we developed our Duros for. As the name suggests, they are made for tough use and are robust down to the last detail. The solid aluminium frame has a geometry that ensures the best possible freedom of movement - for maximum trail action and tricks from tailwhip to 360. Depending on the area of use, a model with single-speed or 9-speed gears is available.
