I will let you know how it goes. Thanks for letting me know in case things go pear shaped.
They fit!!!! They fit perfectly..... The wheels are from a 2004 boxer cup prep and fit my 1999 like they were made for it.... that you all for your input.. this is a great place!!
I've been through some pain fitting PVM wheels to my 1999 R1100S. So I'll kick in here. I also have a post on the pelican board.
My 1999 is an ABS II bike, which means it has the thick ABS rings (5mm thick flanges) with 305mm rotors with Brembo calipers. The later ABS bikes (i.e. 2004) us use the stamped sheet metal ABS rings which are probably the same as non-ABS for the same years with 320mm rotors with the BMW (Tonico) calipers.
Two things you're looking at here, the wheel brake rotor post heights (one side is shorter on the earlier ABS II bikes) AND reliefs cut into the wheel brake rotor posts for the 305mm rotors over the 320mm (do not need the relief cut).
Given what I just stated above, it is a major surprise to me that the 2004 wheel (320mm rotors) fits the 1999 (305mm rotors) but if he says it does, I have to believe it. I would have expected the wheel rotor posts to hit the brake calipers since the later wheels typically did not have the relief cut in them for the smaller and earlier ABS II rotors. The spacers to fill the difference between an early model ABS II rings (thick flange) and the later stamped steel ABS rings makes sense, not later ones fitting an earlier bike as stated, but as I said, if he says it works, I have to believe it.
I've read non ABS wheels will work on later ABS bikes that use the stamped steel ABS rings. I've also read the ABS II rings are interchangeable with the later stamped steel ABS rings (with spacers of course).
Bottom line, later wheels fitting earlier ABS II bikes can be a problem as the wheel brake rotors are typically too tall on one side and you need to verify clearance with smaller 305 mm rotor brake calipers. Earlier ABS II wheels can be made to fit any of the other years using the spacers shown earlier in this thread and their wheel brake rotor posts clear both the 305mm and 320mm brake rotor calipers.
no loss to you Jim, they would not fit your bike. you have early ABS, the mandarin wheels were from/for bikes that have the later ABSi, but is also a match for the early non-ABS bikes.
