    well,,lo n behold,,,while i was gone Zach decided to take my Monzter R1200GS and give it alil hopping up by farkling a new crash-bar,,a set of Ohlins,,and a new set of Superlaced,,Superlite wheels,,sporting shiny black excel A-60 rims size 1.6x21 front and 2.15 x18 rear shod with 90/90 x21 front /140/80x18 rear...

    WHAT??? a 2.15 rear???,,so Zach clued me in that the bike handled even better in the dirt with the narrower rim but wore the center out quicker while on the highway,,,then showed me several other super happy HP-2 riders sporting the wheels he built while i was gone,,,followed by pointing out all the KTM 550's etc came with that rim width and tire combo from the factory,,,

    goes to show ya,,,i got to learn something new everyday,,,well that makes it easy for us now,,to provide the hard core off-roaders the A-60 rim sets,,it'll be cheaper too because we'd always have to add re-anodizing charges for the rear 2.5x18 rim. the A-60s are light AND tougher by circa 15% than the double sig excels.

    FYI..the 18 rear that Jimmy had was our previous 2.5x18,,,for the guys spending alot of pavement time getting to n from their dirt playgrounds liek the wider 3.5x18 tire profile and stability on the road...

    Bottom line,,is we can fine tune rim widths and diameters that serve you better.

    I really like the feedback everyone provides on this thread. I'll hopefully be ordering a wheel or two over sometime in the not so distant future when ever I get back across the pond.

    I'm not sure about poor animals that are killed for meat in Africa,
    sad but true.
    I'm very pleased with 21inch wheel from Woody!
    Huge improvement over stock 19ich especially when traveling
    in third world country's where roads are bad and you can always buy 21inch tire.
    So far over 12000miles without any problems not even flats!
    Thank you very much Woody and all the friendly, very helpful staff in Woody wheel shop in Denver. :clap

    I was about to put my GS-Adventure up for sale to buy a more off road worthy 990Adv when I saw this post!

    I want to clarify that this is simply a swap and i can swap back and forth between the 21/18 and stock 19/17 without issues. I put Ohlins on earlier this year...issues with the 18 rear rubbing?

    In addition to Woodys wheels...i would need brake rotors, ABS ring, anything else?

    As for the front fender removal. Would a piece of pre-filter foam zip tied inside the fairing work? (might be eaier to show in a picture than me trying to describe)

    Woody,
    I just want to clarify...

    the links you sent were reference the Yamaha Tenere, does Wasp's mod apply to the BMW R1200GS-ADV as well?

    I have an '07 GS-Adventure if it makes any difference.

    Thanks

    Mike,
    All you really need is the wheels.
    Everything else you can swap as needed.
    I can go from dirt to street or vise versa in 30 minutes or so swapping rotors.
    Another set of rotors knocks that down by about 15 minutes I would guess.

    swapping either wheels with OEM or Superlite hubs is essentially the same circa 10-15 minutes if wheels are complete with rotors ,,add anothe 15 minutes to swap out the rotors

    some BMW riders will remove the front fender[HINT: reinsert the 4 fender mounting screws,,,,,makes for easier no mud in threads re-install.]

    FYI ,,we are getting back on track to get a higher fender in there as promised a long time ago:wink:

    FYI,,,on early 1100GS we have a 25mm cross-brace raising kit available,,,gives ya a bit more clearance under the fork brace

    Hi Woody,

    How's the development of the higher front fender going. I.... WANT.... ONE....!

    My current Touratech fender that I was using cracked and had to cut the front half off. (figure it was mostly the rough trails flexing it to much).

    For if some are interested, my learning of TKC80's on the front is that this tyre is very flimsy for the big bikes and was soon looking for more grip on tyre edges. At 30psi (front) on hard surface the front end pushed and moved from sidewall flex, (I geuss) and rocks would often hit rather harshly. At 35psi this tyre was much more stable heaps better on rocks but soon found the edges of the tyre far too quickly.

    So from TKC80's now to 908RR's. I really like these in the dirt and like the rear tyre lots everywhere. But the 908 on the front on tarmac can be very interesting and probably doesn't suit my needs, something between a 908rr and a tkc80 is what i need, any ideas? 35psi in the front seemed to high of a pressure very light steering and following lines/grooves on tarmac and no good on dirt. So back to 30psi this feels good on dirt and haven't tried lower pressure's because of the bike at this pressure getting a little headshake reaction from bumps on tarmac at highway speeds. So is a MT21 my next front tyre?

    Cheers :freaky

    ok a quick update,,at long last there is movement in that direction on several fronts,,,
    1,,at last weekends Rawhyde challenge ,i met up with the fine folk from Black Dog who expressed an interest in collaborating on this project

    2,,i just hired on a whipper-snapper design engineer who can take my ideas,,do the Solid Works thing,,,within his first few days here he has already solved some vexing issues modeling a new flip-ski bottom [ i design /build lot's of stuff for the disabled community: www.superlite.org ]
    so we'll keep ya posted,,,

    3,,,FYI,,talking with Jimmy Lewis,,he asserts 26-28 is his favorite air-ressure for the pigs,,,he rides mostly off road,,i myself ride to most of the off-road areas and have settled on 34-36psi..and the 908RRs suite my style just fine....ya have to realize that most of us mortals do not have Jimmy's skill set ,,he has learned the art of truly RIDING versus riding,,,by that i mean he anticipates obstacles ,chooses better lines etc versus just plowing over and through the terrain...the former technique is much easier on the equipment ....

    Ya know I teach that fine art as well as use it on a daily basis. And I'm still continually impressed by the 21/18 setup on my BMW.

    Thanks, looking forward to the update. On another note regarding 21" conversion, came across a GS rider in Alabama talking about the fork spacers he used for his conversion ... what the what?

    Here is an image if someone can clue me in.
