The RAM-B-176-UN4 consists of a fork stem base, double socket arm, diamand adapter base and high strength universal Finger Grip™ holder. This one of the cleanest ways to mount small electronics on your motorcycle. Simply slide the assembly into the hole of the stem and tighten the machine screw to create a tight fit. The universal Finger Grip™ holder is designed to hold a large amount of cell phones and electronic devices. The holder comes with (3 sets) of four flexible rubber coated fingers placed along sides to grip your device. The fingers open by squeezing the ends to open the small finger arms. The bottom of the holder includes a back plate that adds support to the device being held by the mount. The base is designed to fit into the cylindrical bore wall of fork stems and will work with stems that measure from 12-28mm or .5” – 1.10” at the following intervals: Metric 12mm 14mm 16mm 18mm 20mm 28mm Standard .5″ .55″ .63″ .71″ .79″ 1.10 Compatible Motorcycles BMW S1000RR (2009-13) BMW R1200ST (2005-2007) Can-Am Spyder RT-S SE5 (All Years) Ducati 1199 S Panigale (2011-13) Honda CBR250R (2011-13) Honda CBR1000RR Fireblade (2008-13) Honda CBR1100XX (1996-07) Honda CBR600F (1995-98) Honda CBR600F4 (1999-00) Honda CBR600F4i (2001-06) Honda CBR600RR (2003-06) Honda CBR900RR Fireblade (1996-03) Honda CBR929 (2000-01) Honda CBR954 (2002-03) Honda ST1300 Pan European (2003-08) Honda VFR750 (1994-97) Honda VFR800 (1998-13) Honda VFR800 Interceptor (1998-01) Honda VFR800 Interceptor VTEC (2002-06) Honda VFR1200F (2009-13) Honda VTR1000F Superhawk (1997-05) Kawasaki 1400GTR (2007-13) Kawasaki 636 (2003-06) Kawasaki 650R Ninja (2006-13) Kawasaki ZX10R (2004-10) Kawasaki ZX12R Ninja (2000-05) Kawasaki ZX14R (2006-11) Kawasaki ZX6R (1998-99) Kawasaki ZX6R (2000-02) Kawasaki ZX6R (2009-12) Kawasaki ZX6R 636 Ninja (2003-06) Kawasaki ZX6RR (2000-06) Kawasaki ZX9R Ninja (1994-03) Kawasaki ZZR1200 (2002-11) Kawasaki ZZR1400 Ninja (2006-11) Kawasaki ZZR600 (2005-07) Suzuki GSXR1000 (all years) Suzuki GSXR1100 (all years) Suzuki GSXR600 (1996-10) Suzuki GSXR750 (1996-10) Suzuki Hayabusa GSX1300R (1999-13) Suzuki SV650 (1999-02) Suzuki TL1000 (all years) Suzuki V-Strom DL1000 (2002-13) Triumph Daytona (2006-13) Triumph Daytona 675 (2006-13) Triumph Street Triple R (2007-13) Yamaha YZF-R1 (1996-02) Yamaha YZF-R6 (2003-13) Yamaha YZF-R6S (2006-07) .
