HaydenLogo12OrangeWOWordsLocated in sunny Southern California, the Hayden offices are open Monday through Friday 8am to 5pm.The M6 Primary Chain Tensioner was developed and brought to market in 1987. In 1996 we developed it for Sportster XL models. After years of listening to our customers and seeing their need for additional products, we brought to market, in early 1997, the Krank Vent Plus and “The” Oil Fix. Recently, after dealing with issues of the “self adjusting” primary tensioner, we developed our M6 BT-07 for 2007-Up motorcycles, replacing the over tightening, stock unit. We ALWAYS listen to our customers needs, at Hayden Enterprises, customer service is always number one.
