SAMDO 1, 2, 4 Cylinder Motorcycle Digital Odometer Speedometer Tachometer KMH MPH 14000RPM Gear Dirt

Great replacement for my Tao Tao Hellcat 125. I used stock wiring for speedo to the wheel and did a plug swap and it works great. Bright and colorful. NOTE: You’re going to have to calibrate the speedometer to your bike by inputting a three digit code. I’ll save you the headache... someone posted a 21” front wheel is at a 016. I’m at a 12” wheel and I put an input of 045. Gps confirmed accuracy within 1 mph with that input.

Like everyone else the directions are pasted over other directions the wires don’t match up or the plugs are wrong regretting buying this now doesn’t fit a Vader 125 thanks amazon

Saving 100 dollars from buying something else is nice especially when it works without a problem. You may have to repin for your specific harness like I did but it's not hard. The settings are there so you can change how many wires for fuel sensor, how many magnets for the rotor, tire diameter. It reads accurate can't complain.

This thing was NOT a super straightforward install or configuration but overall I am very happy with the accuracy and the functionality of it. I had to: -switch pins for 3rd and 4th gear -switch the connector for my current speedometer -do math to calculate the tire circumference in cm and set the # of magnets to 4 After doing those things, I tested the accuracy of the speedo and it is within 1 mph of accuracy at 25 mph. I like the background color selection and the fact I actually have a digital clock on this bike now. If you're comfortable with moving pins if needed and doing the math you need to get accurate speeds, then you will be happy with this product.

Nothing about this accurate. Impossible to get it to work. Not worth the money. Directions are horrible. The colors listed dont match. The descriptions for each wire they have make zero sense. They need someone that actually speaks English and is from America to make new directions. On top of that I didn't even receive everything listed. I would give zero stars if I could.
