Fork Stem / Hollow Bore Mount, 1" Ball Arm & Diamond Base

The RAM fork stem mount is 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. This part is designed to fit into the cylindrical bore hole of fork stems and will work with stems that measure from 12-20 and 28mm or 0.5" - 1.10" at the following intervals only:

Metric  Standard
12mm  0.5"
14mm  0.55"
16mm  0.63"
18mm  0.71"
20mm  0.79"
28mm  1.10"

Please note:
It is NOT possible to use this part on bore holes of 21mm to 27mm

Ball Size:

1" Rubber Ball "B" Size

If you have a sports bike and want a mount to fit into the centre yoke stem bore hole on your handlebars please check the diameter to determine if it will fit. This is MOST important.

The mount is configured using parts determined by the diameter size of the inner bore cylinder. Check the size of the bore against the gripper washers in the kit. These are 12mm, 14mm, 16mm, 18mm, 20mm and 28mm.

Bikes that this will NOT fit include the following models.

Honda Fireblade CBR 1000RR, Blackbird CBR 1100XX, VTR 1000 SP2, VFR1200, Kawasaki Z1000 SX, ZZR 1100, ZZR1200, ZZR 1400, Aprilia Bikes, Ducati ST series, BMW S1000RR and any bike where a steering damper is fitted.
