I gave the front suspension a little treat today and put in progressive fork springs and new fork oil. The F650 Dakar front suspension is renowned to be a little too soft – the progressive springs will improve bike handling, particularly in off-road situations.
If anyone's in the marked for some new suspension: try Hagon Shocks, http://www.hagon-shocks.co.uk
Hagon have been going since 1958 and have a world class reputation. Besides that, the springs come as a complete kit including the fork oil, and they were by far the cheapest I could find.
