60MM Speedo with 4 Warning Lights LEDs - Black. Nice all-around Speedo for most Japanese motorcycles. The ratio is 1.4 which is therefore very common. The housing is made of powder coated steel.
The LED indicator lights indicate the following:
The counter comes with a mounting bracket and itself has a diameter of 60MM.
The counter goes up to 220 km / h with a ratio of 60 km / h at 1400 RPM. That makes it a 1.4 K value.
If you have questions to calculate the K value (which is 1.4 at this counter); you can solve this with this calculation!
Calculate your K-Value?
K = 10 x number of revolutions of the odometer cable / tyre size in cm.
You can determine the number of revolutions of the odometer cable: remove the odometer cable from the odometer. Put a paper clip on the square inner cable and turn the wheel exactly 10 times (note on the tyre).
Meanwhile, count the number of revolutions that the paper clip/odometer cable makes.
For example: 10 x 27.5 revolutions / 202 cm = 275/202 = 1.36 is rounded 1.4
