Is there any differance in gearing between a tourer and standard? Reason for my question is my ridding budddy's 98 tourer turns 74 mph at 3200 rmp. My 01 standard runs at 65 mph at 3200. All these reading are taken from the stock valk speedo and tac's. Any thoughts?

Which rear tires are on the bikes?
And which on the front? Rear will affect tach readings, front will affect speedo. Either (or both) could be influencing the difference. |

My 01 has Avon venoms and Verns is running E-3's. Both bike are running stock size tires.

I have noted these same differences between my Valk and others that have stock size tires front and rear. It "seems" as if the gearing must be different but I have always assumed that it was in the the mechanicals of the tach and speedo.

The gearing is the same, Standard, Tourer, and Interstate. One way to experience this is to ride close together at the same speed and listen for the exhaust sounds to harmonize. It's fun to have four Valks doing this side by side on a four lane highway.

So what's with the different engine speeds at the same Mph??? |

Many possibilities: Differences in actual tire dimensions manufacturer to manufacturer. Differences in wear on the tires Speedometers showing diffenent indicated speeds for the same RPM One way to test the last one is to use a GPS to compare actual speed to indicated speed. Metric bikes are notoriously incorrect. Mine consistently indicates about 10% faster than I am actually going. |
