Seems that the simplest solution would be just to have flanges made to weld onto the wheels. All that is needed is a T6 plate to cold roll into the proper shape if my info is accurate. At this point I am not even sure that the original flanges need to be removed. If this in fact turns out to be the case then there would be no need to find a lathe with a more than 10 inch swing something that would significantly lower the cost of converting to 17. Truing of the finished weld up can be done on an axle stand with a grinder and a jig and possibly a hydralic jack a very simple setup. Even if the original flanges need to be reduced this also could be done on an axle stand with grinder jig.

If you are setup for metrology I can bring up my extra set of wheels.
The most simple is a 4,5"x17 with a 160/60 tire. The 5,5" fits, too but it starts to become tight. I guess I wouldn`t run a 160 on a 5,5" rim. A 170/60 is still possible but you`ll probably have clearance issues with the chain. (driveability aside I personally think a 4,5" looks poor on the Paso as it`s narrower and higher than the Oscam wheel)What I need is what wheel (for now lets stick to ducati wheels) would make the best exchange.
