    Think I saw someone over at UKGser that did the conversion. Might want to go check out there. Think they said it was great, but highspeed traveling seemed a bit more wobbly.......BUT I'm talking under correction. Rather get a HP2 and be done with it wink

    I have a 21" on my 05 R12GS. I didn't do the full conversion with the wunderlich lower fork clamp and rally mud guard though if thats the conversion you are talking about. I got my wheel from Woody's and kept the original lower fork clamp but I can not use the stock lower mud guard (because of clearance) so I run without it. I really love the 21" though. It really helps a lot off road and doesn't sacrifice much on road. Straight line high speed is more stable now along with fast sweepers. You really only notice a differance on the tight corners on road. Off road it tracks much better, rolls over large obstacles better, adds a little extra ground clearance and alows for slighty faster speeds. The only negative is that without the front lower mud guard there is more tire spray when its raining or when you are going through mud. Call woody though he is very helpful and has all the answers.

    Did it to my 01' GS. It is a bolt on and go once you have the 21" wheel. Someone will have to lace one up for you. GS wheels are not as easy to lace up as your standard tube wheel.

    Pro- Lots of fun in the dirt, far more stable at speed.

    Cons- Not near as good on the street as a 19". The profile on a 19" TKC is nice and round, the 21" TKC is very square.

    I ran to sets of wheels, took about 15 min to swap out the wheels each time.

    How much better in sand??
    Could you post up some pics of the bike and the wheel etc, also any problems you came across, did you sacrifice your front wheel for the hub or did you get a complete new one?

    I haven't had it in deep sand yet with the 21" but i was at the dumont dunes in ca with the 19" and it did well. I have had it in some sand and a lot of deep sticky mud and it definitely does better. There is less rolling resistance in the front and it is easier to steer. I haven't run into any problems at all from it. I did sacrifice my 19" wheel because it was bent. I sent my front and rear wheels to woody's in co and had him lace an HP2 outer wheel to my original hub and at the same time I had him anodize both wheels black. let me know if you have anymore questions.

    There are a lot more choices for a 21" rim than with a 19" but i'm still using the trusted TKC's.

    Looks like you have been having fun, any problems with mud, sems to be min clearance between the wheel and the brace, or does it clear itself ok
    Had some issues with that before.

    Thanks for the answers

    I bought a used 21" a few months ago. It's a Woody's and came with a Dunlop D908RR. Is not tubeless. (I'm wondering if it's possible to make it tubeless)
    I haven't ridden with it yet. But I'm looking forward for some off road riding pretty soon. (Not and easy task around NYC)
    I was reading some reviews about this tire and everybody agreed that was good for off road but it sucks on pavement. I'll check it by myself soon.

    Yeah the bike is tons of fun! I have zero issues with it. If you look at a 650gs dakar it has similar clearance also. It works like a squeegee clearing the mud from the tire. If you try and use the oem lower mud guard it will get plugged up with mud though so I just run without it.

    Hi Rick,
    I have the "TT" 21 inch front with a Saxxes rim on the 1200 GS Hub. The differences I've found so far are.

    1. Surprisingly better in loose gravel & sand ( a lot more planted)
    2. No real difference in Road manners until you really start pushing hard (dragging the pegs, 180 Kmh + etc)
    3. You lose the last 5 % braking before Lockup

    It makes it easy to forget the 300 KG until old Mrs physics catches up & it's time for a wee lie down ( after sliding)

    Regards
    Richard

    Only 180 hey, I presume your talking on the dirt?:evil
    you only did the front?
    where did you get it from?
    did you keep the ABS?
    Can people who were born in a tent," leave the bloody door open" and not get in trouble???
