The double button system, which is an industry first, allows you a choice of settings for different conditions. The upper button is perfect for dry or concrete starts while the lower button is suited for tacky conditions. The double system allows you a choice without changing fork guards. As starting line conditions change throughout the day and from track to track, the Fly Racing Double Button has you covered. Very cool design and man, does it work while still maintaining the same cost as the competitor's single button system.Features: Rebuildable design for long lasting performance Aluminum pin and stainless steel spring resist rusting for continued smooth action Fitment Yamaha YZ80 1993 Yamaha YZ80 1994 Yamaha YZ80 1995 Yamaha YZ80 1996 Yamaha YZ80 1997 Yamaha YZ80 1998 Yamaha YZ80 1999 Yamaha YZ80 2000 Yamaha YZ80 2001 Yamaha YZ85 2002 Yamaha YZ85 2003 Yamaha YZ85 2004 Yamaha YZ85 2005 Yamaha YZ85 2006 Yamaha YZ85 2007 Yamaha YZ85 2008 Yamaha YZ85 2009 Yamaha YZ85 2010 Yamaha YZ85 2011 Yamaha YZ85 2012 Yamaha YZ85 2013 Yamaha YZ85 2014 Yamaha YZ85 2015 Yamaha YZ85 2016 Yamaha YZ85 2017 Yamaha YZ85 2018
