17" wheels on R1200GS

Schtum · 10-19-2008, 11:50 AM

Now I know that, in some respects, this has been done to death but please bear with me..... :)

I know that folks have fitted R1200RT and R1200S cast wheels to GSes but has anyone had any success with K1200S wheels?

I'm having impure thoughts about doing some sprinting/hillclimbing with the GS next year. My son and I are considering double-entering the bike in events like this....

http://nhca.co.uk/Home/nhca.htm

Finding a set of R1200S/RT wheels is proving to be quite difficult and that's before we even get to the point of considering how much a set will cost.......

However, my son just happens to have a nice shiny '07 K1200S. OK, so the wheels are yellow but beggars can't be choosers. Before we go acquiring paddock stands for the K and pulling the wheels off both bikes, has anyone successfully done such a swap? With a little bit of luck, it might just be a case of swapping the front discs and some different spacers on the front spindle as I believe the rear will just bolt on, albeit that it has the wrong offset by about 8mm.

Picture this with yellow yellow K1200S wheels and tyres....

A guy I ride with that I bought my 05 GS from had 17" spoked wheels on it. When he bought his 08, he moved them over to it, so I know it can be done. I believe they were Excel wheels.

Yes, thanks for that. However, I already know it can be done. I've seen several examples of GSes fitted with RT wheels. What I'm wondering is if anyone has successfully fitted cast spoked K1200S wheels, like these ones....

Hi
No the back wheel go's on the wrong way, the spin is back to front

the front is the same as the R1200S wheels, which I do know can be made to fit.

Hi
the back wheel on the K's only spins one way, fitted to the gs it will run backwards.

Anorak · 12-01-2008, 06:29 PM

The back wheel on the K is 5.5 or 6 inches wide and is fitted with a 190mm width tire. That might be overkill if it fit.

Not an engineer, but....

The spokes as shown on the K1200S drive the bike in TENSION.

If reversed, the spokes will drive in Compression.

Don't know if it will have a real impact, but I wouldn't do it.

I do understand that the wheels stop the bike in compression, but??????

Good luck,
Mark

Think of it this way, most vehicles can decelerate at a higher rate than accelerate. Think of the load on the front spokes in a high speed panic stop. The rear of course won't see much. I think the spoke angle is mostly a stylistic affect.

Good enough for me.

Thanks,

Someone posted that the K1200S and R1200S front rims are the same. Very wrong. It is at least 1 inch wider at the hub and will not fit. What is interesting is that the front wheel off of an F800S or ST for that matter is the same wheel. I am running one on my 07 R1200ST to match the rear R1200S. I have several wheels from RT if interested. Thanks

So is this to understand I should be able to shoehorne a F800s front wheel on my 1200 GS ? without to many modifications
