speedo inaccuracy

4980 Views 29 Replies 13 Participants Last post by  toby
Reading different posts I have seen a few of you mention the inaccurate sppedometer on the Stryker. Can anyone explain further as to how off it is, why it is off, and if there is a good fix if the problem is real. The only time I want to be pulled over for speeding is when I actual am speeding. Thanks guys.

Yeah but the bigger tire not only looks better it rides better.

Just a thought..have lots of these :)
Wonder if the speedo is off due to our tires being rounded. Certainly not traveling at same speed on the side when making a curve as we would be going straight. :-\
I don't think so.....doesn't make sense. No matter what part of the tire is touching the ground, it would still travel the same amount of revolutions. Distance traveled divided by time is the formula for speed.

True, but doesn't the smaller diam. get there sooner?
i keep telling my wife that but she laughs at me

You're thinking too hard on this one... At a given RPM, you might be going faster on top of the tire vs on the side of the tire. I can agree with that. But the speedo gets it's reading from inside the engine/tranny somewhere. It doesn't matter what part of the tire you're riding on... And besides, most of the time when people check their speed, they are traveling in a straight line anyway.

Another theory proved wrong.

Just tested this tonight. Straight line highway showed ~65 mph on my speedo, friend in a car read me at ~58. Really depressing that we will have to do aftermarket stuff to a bike just to make it honest. :-\
i hear ya man that's some bullshit. When i buy a brand new vehicle i expect it to be good to go right off the assembly line. I'm just going to put a 240 on it once the factory tire needs replacement. The Dunlop Elite 3 240 is actually cheaper than the OE 210 is.
Yep, bullshiit............but the VTX was off by 10% also. Wonder if all metrics are off and how about HDs?
