    ooo this looks cool... Firstly can someone tell me where I can get these 'WP' forks please?

    Whats the cost? did you need to change the triples? or do they just solt right in and give you ground clearance and better suspension?

    Cheers,

    So ... I've been on this sojourn of Mexico and Central America for about a year now....
    I've rolled up a bunch of miles on my 2009 BMW F650GS (twin).
    The ride is chronicled to some extent here:
    https://advrider.com/index.php?threads/riding-the-tat-to-costa-rica.1253620/

    I've ridden pretty hard, and I'm confident that when I get back home it will be time to replace the OEM rear shock.

    My only hard requirement is that I need a unit with a handwheel on it so I can adjust the spring preload on without getting out wrenches.

    For my 10-year old friend I'm interested in a "budget" replacement.
    If I could find an OEM take-off with low miles on it, I'd be fine with that...
    (I might swap out the spring for a progressive unit or shim the OEM spring up just a bit but otherwise it would be good enough)

    Anybody got any suggestions?

    thanks @Loutre

    Earlier on this thread (I think) someone was saying the 800 version had 10mm more of travel which would dick things up...........
    I'll have to track that down............................ :doh

    Yeah the F800GS shock is longer and will raise the rear of the bike. Works well if you are raising the front with longer better forks at the same, otherwise I wouldn't do it.

    You guys ....
    Don't let Reaver hear you talking .... :pynd

    I looked on the Ohlins page just for comparison.

    They have discontinued the rear shock assby for the F658GS :scratch - it was P/N: BM 304 with stroke of 51 (I presume millimeters but they don't say)
    They still make the unit for the F800GS P/N: BM 303 with stroke of 69

    So since I don't want to go jacking up the front of the bike ... I guess I'll pas....:hmmmmm but thanks!

    Less preload would drop the rear, no?

    Yes ... it would but then would the preload / sag adjustment be out of whack?

    I don't have my mail-order degree in suspension tuning yet .... :cromag
