229:(D50B0/D50B1). This engine is used in the Derbi Senda DRD/X-Race/X-Treme supermotos and crossers, as well as the 2006 onwards Derbi GPR 50 and Aprilia RS 50 road bikes, although the road bikes feature an electric starter instead of a kickstarter on the supermotos. Engine parts from the crossers and supermotos can be directly swapped with one another; there are some small differences between the road bike and supermoto engine and frame which may require modification to transfer some external engine parts (exhaust, airbox etc.)
