Update 9/11/2014: The design of this wrench has been revised, the updated version fits all BMW Airhead nuts (including large finned models), does not engage every fin so bent ones can be skipped and weighs only 5oz. Price remains the same at $35. BMW Airhead Exhaust Nut Wrench: Strong enough for daily use, but light and small enough to be carried in your tool kit also. Uses stock BMW lug wrench for leverage, eliminating unnecessary size and weight. CNC machined from billet aluminum and anodized. $35.00 plus $5.00 for shipping. (USA) Thanks for looking!
