on my DR650, the stock bars without weights were so bad that I didnt even make it 5 miles before going back home.
My handguards now do the job of weights to keep the vibrations from turning my hands into leaden nubs at the ends of my arms.
“Life should not be a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside in a cloud of smoke, thoroughly used up, totally worn out, and loudly proclaiming "Wow! What a Ride!”
