QuoteDoesnt this look straight forward?

Quoteand the axle and a few machined pieces were fabricated to allow the fitment of Sport Classic wire wheels 

Probably not so straight forward...

Darn!! My only experience with a wheel swap is 848 wheels on a Ducati s2r1k and that was very straight forward :) I was hoping for only one higher level of difficulty :)

Gets waaay more complicated when the axle diameters are different. Sometimes it's hard to source bearings with the smaller inner diameter that have the same thickness as the OEM bearings. That involves spacer length issues.

The ST front forks will simplify the front half of this.

I’m wondering if a 17.05mm ID / 24.95mm OD sleeve may be the fastest way forward.  Dimensions are subject to being wrong, this is just meant to convey a thought I had.

If he can use the 17mm sprocket carrier with a remade tophat spacer, that will keep his existing chainline.
Aforementioned 17.05/24.95 spacer for the wheel itself
Modded/made-to-fit caliper hanger
Gamble that the rim is in the proper position laterally
Redish wheel if it's not.

I was thinking all the way across minus a small dimension so that the lateral tension from tightening the axle would lock the OE 25mm axle  spacers.

I'd go one step further and use a sleeve retaining compound on the 'bushings' to ease assembly.

Yeah, the width is a gamble as well as chain alignment.  If it were me, I’d get the 25mm caliper hanger from the GT1000 and use it.

This is all a gamble...

Yes, if he can use the SC sprocket carrier and caliper hanger.

I think he's forced to use the SC caliper hanger to provide proper positioning of the caliper, I'm 99% sure the lateral positioning is different.

A 17mm rear axle slips snugly by hand INSIDE a stock Ducati 25mm rear axle.  Seems that could be the fastest way to adapt bearing ID in this case.

Sorry, no photo.

Tested inside a 2003 M1000 rear axle.
