Digital Speedometer Accuracy

For what it's worth, I was riding my TT250 and noticed the radar speed sign always had me at 3mph lower than my digital speedometer showed. Decided to hook up my Garmin GPS and see what it showed. Yep, looks like the digital cluster is about 3mph off. Not a big deal...

That's dang close!. I have yet to have an accurate speedo on a bike. I've never really saw it as that big-a-deal really. The safest speed on a bike is "flow of traffic" anyway.

We have Matt's cluster on our TT250 (first year, analog speedo stock) and I believe if you set it for 19" front wheel, it's exact. Maybe someone can correct me on this.

That's interesting. I wonder if the speedo that comes with the TT250 is the same as the one Matt's sells? Maybe the TT250 is programable too?

You can get a Trail Tech Vapor mph dialed in and get those numbers down into the hundredths place... 0.0X mph off
