Wanting to put a 17" wheel on the rear to replace the wide 18" (for easier access to tyres and greater choices) I bought a K1200RS rear wheel on fleabay for a seemingly good price. When it arrived I found it was actually an R1150 rear wheel, still 5.0 x 17" but with cast mountings for the rear disk built into the wheel. I got a refund and told to keep the wheel as postage back was just an extra cost to the vendor.
So I have a free wheel to play with. I cut the disk mountings off after a few hours of graft and the use of many different cutting and abrasive tools.
I hadnt considered that the 2 different wheels may have a different offset but it appears they do. I've fitted a Metzeler Roadtec Z6 front and rear (after a disappointing <10,000kms on a pair of Angel GTs).
Visually from the rear you can easily see the tyre is fitted left of the centreline. A test ride proved the bike is quite safe to ride, doesnt display any evil handling traits, but if you take your hands off the bars it turns to the right every time. I can fit a whole finger between the tyre tread and the swingarm without compressing my finger much at all so I have a fair bit of leeway.
So next mod will be the get some material removed from the bolt face to shift the wheel back towards the centre (not running any spacers at this stage. I'm thinking 10mm as I can always use spacers to bring it back the other way if needed.

PS: The wide RS 18" wheel is not for sale as I want it to be available for the day I will want to put the bike back to bone standard. However if someone (local) wants to borrow it to see how their bike feels with a wider rear before committing to buying one I'm open to requests. It has an Angel GT Radial fitted with maybe 1000km to go before it hits the wear markers.
