I recently bought a BMW GS310 motorbike for 5.5k (new, not used), that is just 500 Euros more than my Mountainbike did cost. Sure, the BW is an entry level model, and the MTB is upper class, but still. Mountainbike prices are a rip off, especially if you consider that after 3 years you will have problems getting spare parts for some stuff on the bike.
