F650GS Fork Components

Background

The 650GS front forks are a simple plunger design with a leading axle. The design has not changed since the release of the F650GS in 2000 through to the 2010 G650GS. Some components have been upgraded (Fork Yokes, Fork Brace, Axle, RHS Axle Spacer) with the revised components superseding the parts for the earlier year models.

Fork Assembly
Part No's

There are 3 Part No's for complete fork leg assemblies covering the period 2000 to 2010 including the G Series. The newer revision parts are backward compatible with the early year model machines. The reasons for the part number changes are unknown as the individual Part No's researched remain the same.

Fork Slider
Part No's

There are 2 versions of fork sliders 2000 to 2010 with the same Part No. The 2011 model has a 3rd version. The 2011 Part No's are not well documented in the on line parts Fiche. There are some internal component Part No differences with the 2000 to 2010 forks. The most obvious is the use of a 10mm bolt retaining the damper rod at the bottom of the fork slider (up from 8mm). The earlier sliders would fit if the old ABS sensor was used and the slider retaining bolt hole was increased to 10mm.
