I've had a 97 M900 for about a year now. Finally got around to having a new tire put on. I pulled the wheel myself, had the tire put on and put the wheel back on yesterday. Everything seems fine except now the plastic hub that the speedometer cable goes into seems a little too close to the rotors (discs) on the wheel. I thought maybe I left out a spacer or something but no extra parts were found. The problem is now when I slide the rubber boot over the nut on the speedo cable it rubs against the fastners that hold the rotor to the wheel. Perhaps the boot was never that far down in the first place, it's just something I didn't pay that much attention to when I removed the wheel. The threads on the plastic part are just about an eight of an inch away from the fastners on the rotor. Is this a normal clearance?

I no longer have my 1997 M900, but took the front wheel off several times and I don't remember any spacers for the front wheel. There is a brass colored speedometer drive that goes in between the wheel and the speedometer gears, but if you left that out, it wouldn't change the spacing at all. As long as the wheel rotates freely with nothing dragging, you should be fine.

Thanks for your response, everything is fine. No extra parts and it went on just the way it came off, it's just that the rubber boot that slides onto the nut on speedo cable rubs against the disc fasteners. It wasn't before. I guess it's possible that the boot was slid away from the nut in the first place. There's very little clearance anyway. I'll see about posting a pic to illustrate what I mean.

you might have rotated the speedo drive a bit when reinstalling, that's possible and it happens... pic would be good though

You can tell from the pic that the threaded part of the plastic hub is only about a nickel's thickness from the rotor fasteners. That's fine until you try and slide the boot on, then the fasteners rub against the boot really bad. It may not be a factory cable or boot but I it wasn't rubbing before. I've only had the bike for a little over a year so not sure what the previous owner might have done with non OEM parts.

I've never seen such a big black rubber piece on a Ducati speedometer cable. That thing would definitely not work on my ST2.

I have but at the other end. Maybe you switched the fittings?
I had no rubber at the wheel fitting.

just checked my speedo cable and I don't have the black boot either (I have a 2000). I know at least one or two or maybe all the previous year models did have that boot.

If the boot were there, it would definitely catch on the disc carrier mount bolts as in yours...

I never removed the cable at the speedometer. I guess it's quite possible that the previous owner did the switch from one end to the other and the boot indeed is supposed to be at the speedometer. I'm not too worried about moisture at the hub end anyway since I'm a fair weather rider so I'll just remove the boot and not worry about it. Thanks for all the input. Next time I tackle something new on this bike I'll just snap a few photos first and use them as reference when I put it back together.

oh, you didn't mention that there was no boot on the other end, yeah, the cable's most likely reversed, I'd go ahead and just reverse it back, it's a very easy operation to do.

The inner cable has a detent on one side and none on the other, i don't forsee a problem, but it just 'feels' better to have gravity pulling the detent down on the mechanical stop... but again, i doubt there would be any real problems if you left it...

Mine has boots on both ends ('01) but the boots do not cover the knurled part and are the same thickness. The boot in the photo looks like it comes from a spark plug wire.

yeah, the older cables came with boots on both ends that were different, the one he's got there is the same as the one I've got on the gauge side

There's no boot at all on the gauge side so I'm sure it's on backwards. I just cut off the biggest part of the boot and slid it on down to where the plastic begins on the hub. Should be good enough. Seems to make more sense to protect the cable connection down at the wheel where it collects more dirt and moisture than on the gauge side anyway. Maybe that's what the previous owner was thinking.
