That depends on the rider, of course. The most common question is how will my 650cc KLR or KTM 690 Enduro do on the dual sport ride. Again, that depends on the rider. But usually the 650 and larger bikes struggle on the dual sport ride as they are heavier and the dual sport ride is narrow single track with quite a bit of elevation changes. Having said that, we have had KTM 990s complete the dual sport ride. It all goes back to the rider.
