I can understand what you're saying...but I don't agree. I've owned a number of cars, trucks, suvs, and motorcycles over the years. The cars and trucks all had accurate speedos when referenced against a GPS unit. My KLR650 was accurate. My ST3...pretty much 10% over. It's completely ridiculous that Ducati sets the speed so high when the vast majority of other manufacturers are pretty much spot on.There’s several reasons for OEM speedos to read fast.
One is there’s HUGE federal penalties for even one vehicle having a speedo that reads lower than actual speed. Second, there’s tolerances, or margins of error, in every component of the system. Third, tires have tolerances as well, affecting their circumference. Fourth, as tires wear, they get smaller and rotate faster.
Read my F‘ing post.No. The speedo is programmed to read higher than actual speed by a set percentage. Ducati’s for about the past 15 years were programmed to read 8% fast. It looks like the newer Multistrada have changed it to 5%.
Traffic investigator or not. You sir are lucky to have a "close to accurate" speedometer on a Ducati. Every Ducati that I'm aware of (and that's not just one, so my sample size just may bit a bit larger than yours) has the same optimistic speedometer. There even was a cottage industry set up to address the speedo errors.Read my F‘ing post.
That’s my background and experience, what’s yours?
I have a buddy who argued and got out of a 5mph over the limit in a construction zone speeding ticket (there are those cops out there) with his helmet gopro footage. If he was displaying over the speed limit, that would have been hard to do, albeit this is probably a pretty circumstantial case.Why does anyone care if it's not accurate by 5% or whatever.
The bit people are missing out is that the legal requirement for speedos is that they are slow for legal speeds. After that, other stuff happens, which only ppl debating the subtleties thereof on a forum such as this have any right to know about.
