    Removing the rear wheel on your F-Twin F650/700/800 with chain drive

    Time for new rubber on your F-Twin? Did you ride past a construction site and now your rear tire resembles Swiss Cheese? Let's get that wheel off!

    Note 1: The specific bike shown is a 2013 F800GS
    Note 2: The tools and materials used are by personal choice and are not due to any affiliation with any brand

    Materials needed:
    - Staburags NBU 30 PTM or equivalent grease

    Tools Required:
    - 24 mm socket
    - T25 Torx (star) bit
    - Ratchet that fits the above
    - Breaker bar (optional, but may be needed as the axle nut is quite tight)

    To create some space in the rear caliper, firmly push the brake caliper against the disc to force the caliper piston in.

    Then place the bike up on the center stand or an appropriate stand to allow the rear wheel to be above the floor. Please make sure that the bike will not fall over! I like to run a strap from the center stand through the front wheel to prevent the center stand from folding up.

    Remove the speed/ABS sensor from it's housing on the rear wheel using your T25 star (Torx) bit as indicated by the green arrow. Tie the speed sensor and wire up and out of the way.


    Note: this bike has an aftermarket bracket that covers the original speed/ABS sensor (10 mm bolt).

    So I don't have to fiddle with setting the proper chain tension when the wheel is reinstalled, I mark the location of the chain adjusters.

    This post (#5) and the next post (#6) show the "by the book" way of getting the chain off the sprocket. The last time I changed tires, I was able to remove the axle nut, and then remove the chain slack adjuster stop (the L-shaped piece behind the axle nut). This allowed me enough room to push the axle forward, without changing my chain slack settings. You may or may not have enough chain slack to do this, but it may save you a minute or two during reassembly.

    "By the book" option:
    Using your 13 mm open-ended wrench, loosen the lock nut on the chain adjusters. Then, loosen both the throttle side and the clutch side chain adjusters so that you create excess chain slack.

    Using your 24mm socket and ratchet/breaker bar, loosen and remove the axle nut.
