I've been wondering when this subject would come up again  ;D

Definitely something I would consider if I had a big Beemer.

OK - did my research - Parts are on order - you can do this really reasonably for about R4700 if you're prepared to go tubed, or just over R6000  :biggrin: if you want to stay tubless. This is of course based on the assumption you're prepared to re-use you hub, otherwise you'd have to cost that plus a set of brake discs in if you wanted to put a road tyre on your 19" wheel, and swop out to the 21" with offroad tyre when you head for the dirt. I'm happy to just have the 21" and keep my old rim and spokes in case I ever need them.

The rim that is used to do the conversion is R100GSPD, it's available on back order from BMW, don't let them try rip you off - the first dealer I went to quoted me over R8000 and had no idea when it would get here, Auto Atlantic BMW quoted R4087 and said it would be 3 weeks, but you still then need to pay someone to annodise it black, (unless your'e prepared to stay with silver). The other option and the one I'm going for is to have Woody's in the US ( e-mail; woodyswheelworks@gmail.com check their website www.woodyswheelworks.com ) send me one already annodised black - will cost about R4500 supplied, annodised, posted and vat when it gets here.

For the spokes, you use a set of HP2 which will cost you R1088 for a set of 40, you can re-use the nipples from your current spokes.

In terms of lacing a trueing, you will come across threads which say this is a mysterious art which virtually no one can do, have come across Nicholas (072 605 0727) here in Cape Town, thanks to Shane from V&A BMW, he says he will do the rebuild for R500, now I don't know yet how that aspect will go, but he says he gets it to within 0.5mm which is well within the BMW spec.

Will keep the group informed how it goes, but it looks like I'm on track to do the whole convresion for a shade over R6000, excluding of course the actual tyre.

Nicholas I mentioned also does the complete conversion for you for R15 000, including fitting of a new beefy triple clamp which allows re-use of the front mudgoard. I may purchase the triple clamp from him for R3500 when I've recovered from the initital conversion

You can do this conversion even cheaper if your'e prepared to go tubed, Woody's will send you a black Excel rim and set of spokes that will work. That will only cost you $255 for the rim, $180 for the spokes and nipples $60 S&H, VAT, Lacing and trueing, you'd be at about R4700 excluding the tyre.
Biking history excluding project bikes - Yamaha's: DT50LC, DT250, XT500 & 1200 Super Tenere. BMW's: F650, R80G/S, K75, R100RS, 1200GS & 1200GSA, Triumph Tiger 885. Honda's: Africa Twin's x 3 & Varadero 1000. Now back to BMW 1200 GSA

This makes so much sense. I could never understand why BMW decided to go with the 19 inch on the front on the R1200GS Adv. It is suppose to be a go anywhere tourer and the 21 inch front makes so much sense.

Great project well done!

I am sure the cost would be the same Kilroy, only the hub might be different.

I have the Wundelich 21inch conversion kit on my GS and a Ralle Moto steering damper.

I will NEVER get rid of this bike and I smile everytime I ride it.

I did a lot of research before I fitted the kit - contacting others that have done it - here and in the USA. This was the message: - Should have done it long time ago, - never regretted,  -will do so all over again...

The offroad handling is in a different league and even on tar, I like it better how the bike corners
