Speedo Reading

[Chris Canning]

Can anyone running the stock 46 rear with a 19 front give me some speedo readings at 5/6/7k mine is running a little slow and I have a gizmo that I fitted when I went to a 17" front wheel so I can alter it.

That's my configuration... when do you need it by?

It's been cloudy and cold here... I haven't been riding much.

There's no rush.

Chris, my speedo is spot on according to my GPS and with a 19 front I run 5600 at 90mph.  On the 18 tooth it used to be 6000 = 90.

that should get you close, then on a straight bit of road, check it with GPS.

Cheers Bix that'll do.

Chris, according to a gearing calculator on the net, with your set up, I'm assuming a 180/55 rear?. At 6000 in top your bike should be doing around 97 MPH.  5000 in top and your still potentially in trouble (81).

Pretty cool site, have a look  http://www.gearingcommander.com/
