NOTE – there is seven in our group all with wide ratio gearboxes fitted to their DRZ’s. Mine was done from brand new as well as the 434 kit ( some refer to it as a 440 kit ) Others in the group have had WR gearboxes fitted on their bikes from a couple thousand klms to sixty thousand klms. One is standard 400, most with a 434 kit and two with 470 stroker kits. Let’s face it less revs equals less wear, less fuel and a longer life for these bikes. From single track to high speed transport the wide ratio gearbox transforms your bike. If you want the best lightweight adventure bike in the world this is it.
