Can a 17mm axel front wheel be adapted to a 25mm axel?

I know people have done it the other way around, but I really don't want to have to change my wheel set just yet. Does anyone know if bearings are available to adapt this?

I can't help....

I'm just waiting for someone to tell you your axle is 20mm not 17. ;D

Ah crap, you got me Nate... it's the rear that's 17 right?

No...No ...No...

My 96 actually has a 17mm front axle.

There weren't many bikes built that way.

It's entirely possible on the early bikes.

Pretty sure the rears were 20 mm.

Aww see, you made me second guess myself.

I have a '97 and it has a 17mm front axel.

Do you know the OD and thickness of the 17mm bearing?

If the OD of the axle bearing will allow I can`t see why not, but this a Ducati afterall so it might be a huge problem that only lots of dollars can fix ;) ;D
Never attribute to malice that which can be adequately explained by stupidity.

I'll get some measurements on the current bearings.

You need some 361203R SKF bearings

You sound pretty sure about that, are you 100% sure on that?

I looked that bearing up online, and it has a 17mm inside diameter.

You are wright this bearings are for 17mm axel in a 25mm frontwheel  [bang] [bang] [bang]

So no one's ever tried this?

I'll get some OD bearing dimensions when I take the front end apart next weekend.

You may want a thickness too.

IIRC the available bearings for the 20 mm axle to 25 swap made the bearing journal too shallow and required machining.

As an alternative why not make bushings for the axle you have?

I did this for the rear wheel.  They don't make a bearing the right width, so I had to have a machine shop make me a spacer for each side of the wheel so the bearings would sit flush.

My current front axel is 17mm, as is my wheel, and its bearings. I want to swap forks to a set with a 25mm front axel. I could get new rims, but to be honest, I just haven't found a set I like.

Or did you mean bushings to space the axel out to the forks?
