I was noticing this as well - but it was more a flow of traffic thing. I've been commuting the same road for 5 years and the other day was doing 70 in the right hand lane. Problem is the right hand lane on this road NEVER does more than 65. And I mean NEVER.It is a known problem. You can fix it by changing your sprockets. I'm going 17/46 here shortly and that's supposed to bring it right in line with the proper speeds.
Well, that would explain it. Crap - that drove me crazy in my bimmer - constantly doing math to make sure I was within the margin of error. Really sucked. 65 on the bike felt like 60.The speedometer is about 7% overly optimistic.
Adding +1 to your front sprocket pretty much fixes this.
Common.Hi everyone, my FZ6R is still relatively new, I have just over 2500 miles on it. I noticed a few days ago that my speedometer and flow of traffic weren't quite matching up, so I found my self an electronic speed sign and twice it read different than my bike, today I paced against a vehicle I know is correct and yes my speedometer is 5 miles off, is this a common problem? Is it fixable? I really hate doing math while simply trying to enjoy the ride.
Shame there is no way to electronically calibrate the speedo. Had to do that on my Jeep when I put 35's on it. Programmer took care of that.
you are so helpful you deserve some rep!
If you look at my post, I posted that, plus the SpeedoDRD, which is much cheaper.
The only problem is when you fix the speedometer, you will end up with an odometer that is off about 7%. You will indicate less miles that you are traveling.
