Most speedo's are calibrated to be fast.
I have a VR1 electronic speedo which is calibrated by wheel rpm and the measured circumference of the wheel.
With the D404's the speedo matched the VR1 dead on.
Yup, my speedometer always read low with the stock IRC tires. Having the wife's cage follow and speed, the D404's I put on are about 1mph high, instead of about 5mph low.
I was VERY surprised at the 6mph difference on my 01. But it reads closer now
