G650 Chain. Get a D.I.D. 520VM or 520VM Gold on E-bay for about $80 and a set of JT STEEL sprockets for about $50-$60 for both, also on Ebay. A chain breaker/ rivet tool is about $25-$35 there as well. Ebay is your friend! Not a hard job at all.
This BMW was unlike any before. The Dakar edition has useful offroad upgrades such as beefier and taller suspension and a larger front wheel. The seat height of the Dakar is 34.5 inches, compares to 30.7 inches for the base F650 GS. The Dakar also has a unique look to it, distinguishing the bike from lesser models.
F650 Dakar Rollers. As noted above the Dakar has TWO Rollers, an Upper one the same as the GS and a big Lower Roller. Image 1 Image 2 Image 3. The checking and installation procedure for the Upper Roller are the same as for the Classic Upper Roller. The Torque Value is 21Nm. The Dakar Upper Roller uses a M6 X 100mm - Z1 Bolt
