Please help. On an XB in a rear wheel skid incident will the speedo drop to zero?

Your speedo is driven off an electric sensor plugged into the top of the tranny. When the rear wheel is not moving the speedo should read zero.

Is there any reason that you're asking this question? Just curious. ; )

By the by, on the S2's and some other earlier Buells the speedo is cable driven off the front wheel, so as long as the front wheel is moving the speedo will read, but if you can loft a long wheelie at 60mph and get the front wheel to stop the speedo will read zero. What happens when the front wheel lands back on pavement is subject to debate, usually nothing, sometimes something, depending on the road conditions, tire condition, rider condition, and bike setup.

Still curious what prompted your question though.

Oh, and welcome to the site here. Post more and join in the fun. There's a bunch on folks on the site here from AZ.

I smashed into a truck and my lawyer thought the other side might take notice of the speedo which is crushed. I crushed it with my nuts apparently. OUCH! It is stuck at 42MPH but I was in a 10 foot rear wheel skid at impact, so the numbers must be wrong.
Thanks for the help.

Maybe your nutz were going 42mph at the time of impact.

Your speedo has a needle that is electrically controlled. With the impact it could have stuck at 120mph if you hit it right since you hit it hard enough to crush it. Try tapping on the side of the speedo and see if the needle moves any. Without a black-box recording data just prior to impact there is no way to tell by looking at the speedo how fast you were going at impact beyond a reasonable doubt.

Got a pic of the bike with the crushed speedo? I'm trying to imagine how that portion of your anatomy could contact that portion of your bike what with your legs and the handlebars working in unison as obstacles getting in the way of the impact. That had to have hurt. Sorry to hear about the wreck.

Another thing to consider is maybe the electric to the speedo got momentarily interrupted at impact. I recall that when XB's are first turned on the needles do a full sweep of the dial. If your bike's speedo had a momentary disconnect of elect. to the speedo it could have triggered a reset and your impact may have caught it in mid-sweep. Don't know, just postulating here trying to think what may make it stop where it did. Hope this helps in some small way.

Take care.

Yeah, it hurt. I Almost lost my leg. I have three Titanium rods a plate and 15 screws holding me together. I have had 14 surgeries and at least one more to go. I believe I am alive thanks to my Shoe X11.

What you really cant see here is the jugs ripped off the block, both wheels crushed, and more.
