The Michelin desert 17 was made in small series and the tolerances was quite big. Some tires are wider then others. It was common that people had to shave the tire even if they used the 5mm spacer.
Depending on what shock you use it might hit your mudguard when the shock gets compressed. It's possible to raise the mudguard a bit but by removing the spacers at the rear mounting-point but I doubt it will be enough.
You can get 1mm spacers from BMW (it was used for some K-models) to trim this but you have to decide if you need longer bolts or not. I'm not a fan of spacers...
Instead of using spacers it would have been better to respoke the wheel with offset, but that's quite expensive.
The tolerances are not on your side, some examples (R80GS Basic):
- I've had one Michelin T63 (130/80-17) which rubbed the swing-arm slightly, at least ten that didn't.
- Pirelli MT21 (130/90-17) hits the mudguard when the tire is new and I have luggage (subframe flexes). I have not experienced this with the Øhlins shock, but it happened regularly with the WP-shock.
So there is no simple answer to your question, it will work if you are willing to do the modifications needed for your bike and the tire you get and you can live with the compromises. The real question is why going to all this to install a tire that have been obsolete for years when there are other good choices out there?
