Okay, here's the deal. I got popped for doing 125+ in a 65 in California last summer. Under the law, I was up against a $500 fine, 90-day suspension and possible jail time. When the CHP pulled me over (I was originally clocked by a plane), I was doing 70 and I was very, very polite after I stopped, so they didn't arrest me or take my bike. Needless to say, I didn't really feel like riding anymore, despite the fact that I had an 80-mile ride home.
This was a mandatory appearance violation, so I had some time to strategize. This is what I came up with, and it might work for you. I decided to go with the "My speedometer is inaccurate" defense, so I needed paperwork to verify this. I changed both front and rear sprockets, the largest I could find for the front and the smallest for the rear. I then had the bike dyno'd and it showed a minimum 10% discrepancy on the speedo! Now I know what you're saying, "That's still 112.5 MPH", and you're right. But, under the California vehicular codes, they cite you for "speed in excess of 100 MPH" which can also carry a reckless driving with it. This violation is what the judge sees. When I presented my case in traffic court, I showed the judge my paperwork from the dyno. I did not mention the gearing change as I was not asked. I was then convicted of simple speeding with no reckless or license suspension attached to it. I walked with a $150 fine, a bargain in comparison!
Yes, this is not the most ethical approach, but they play their games, so I play mine. I hope I've helped in my little way. Fly low!
Keep the rubber side down!...STC
