Review on Extreme Max 5600 3211 Motorcycle Swingarm by Ryan Whatley

They fit perfectly on my 2017 Kawasaki Z650. You will need swingarm coils and possibly aluminum if you have a standard exhaust. They keep my bike rigid with no lateral play or movement. I can push the bike properly on the stands and it doesn't tip over or even wobble. Follow the additional installation instructions to tighten the mounting screws and they are very sturdy. The plastic tabs on the stands are a weak point and break easily. One of mine broke on arrival but you don't really need them - I took them off and threw them away. The manufacturer will send you a replacement if it breaks. Expensive coasters may or may not be sturdier, but I don't need more than what they can. This is great value for money.
