School me on suspension...

Discussion in 'Bike Reviews, Questions and Suggestions' at netrider.net.au started by JaddoFett, Mar 17, 2016.

  1. Hey hey....

    I've seen this suspension setup on a few bikes on the net, but it seems to only ever be on BMW's (R60's?).
    Is that because it's only used by BMW?

    Any info would be great.

    I think it's a really interesting look, but is it useful/effective suspension?

    How old are the bikes that use this setup?

    Thanks. :)

  2. It's called Plunger Suspension. Mid century bikes from BMW, BSA, Ariel, etc. utilised it. Relies on a combination of springs in the plunger tube, the rubber tyre, and the springs in the seat to provide suspension. Constrains real wheel travel, and obviously inferior to swingarm suspension.

  6. Oh ok, cool. Thanks.

    I imagine it would be in between a rigid frame and swing arm suspension in terms of effectiveness..
    Surely it couldn't be worse than a rigid frame.
