Has anyone attempted to calibrate their speedometer?  I was finally took my bike out for the first time.  Was having a hell of a time on the bike until I looked down and I realized I hit 110+.  I slowed it down but I seem to be averaging 80+ while riding with traffic.  Just didn't seem right.  I know traffic don't usually move that fast because I drive a really slow truck.

So I rode the bike again today but this time equipped with GPS to verify speed and sure enough the bike is off by roughly 10%. 

Has anyone tried installing a speedohealer?  I'm pretty sure due to regulations Energica was forced to do this.  What I'm not sure of is if there is a pulsed speed signal coming out of the Bosch ABS to the ECM OR if the speed is sent via a CAN bus.  If the speed is a pulsed signal we can use a spoeedohealer.. If speed signal is sent via CAN Bus , then I think my only option is to machine a new reluctor wheel with 10% less spaces. 

So with that said, hows everyone else dealing with this speedo issue?

It's a known thing. Basically based off regulations you get hugely penalized if you're under, but it's ok if you're over. These bikes do tend to be over by 10% or so as you noted. Unfortunately it's motor RPM based. You can't really calibrate it.

The good news is the odometer is eerily accurate.

European bikes, such as my Energica and TTSE read high.  I think this is because of the speed cameras that are common in Europe.


USA bikes, Harley and even Zero, are quite accurate.  Japanese bikes  also read a little high. But the European bikes are ridiculously high.


I have a GPS on every one of my bikes and that is what I use for my speed.

What is the basis of you declaring that the speed is based off the motor?

put it on rear stands, put the kick stand up, and apply throttle

edit- or change the sprocket size and apply throttle

Confirmed.  Its getting its speed from the motor.  I disconnected the REAR abs sensor while on the stand and it indeed registered speed.   Now it just became a lot harder to change!  I guess I'll have to see if theres anything I can do on the odb2 interface or if I have to just live with it.

I don't see why anybody even cares. It is easy enough to subtract 7 MPH from your reading. Or just add a GPS and use it.


IMO, all electric bikes should have a GPS just to help find the charge stations and see how far it is to get there.

But at this price point is an accurate speedometer really too much to ask? We aren't exactly talking cheap low-end scooters here. And yes like DonTom I have a speedometer so I can see true speed. All of this also means the top speed on a Ribelle is only about 112 MPH, not the 125 they advertise. Or maybe we should be glad they didn't want to claim a top speed of 200 MPH as all they have to do is change the amount of speedometer error.

I wasn't going to respond but I will make this my last post before I disable my account on this forum.   You really have no business telling others what they should care about or not.  I paid a lot of money for this bike and I expected my speed to be relatively close to accurate.   And why should I have to mount a cell phone or another device just to get my speed?   

Anyway seems like there isn't much good information or advice here. I'll take my questions else where.

Dang I thought I was being helpful.

It should still do the 125 MPH under perfect conditions but your speedometer should then read around 140 MPH. The indicated speed has nothing to do with the real top speed they claim. Or at least it shouldn't.

By law,  in many countries,  a speedometer may not read low. So they deliberately make them read high so as things change (even tire wear or different tires can effect such a little) it will never read low.


IMO, it's not a big deal. It's designed to read high on purpose.

My Royal Enfield's speedometer also reads a little high. I always figured that was because the company wanted you to pretend that the bike could go faster than it really can.

I'm going to pick in this conversation because I'm annoyed by that speedometer that lies so much for almost 2 years now, it's not my concern that it deviates at top speed by more than 25 km/h, but that it does not reach the promised top speed of 200 km/h as a result. The speedo continues to 210 km/h and hits the limiter, in reality it is about 185 km/h and because it is limited to the value that the speedo displays, that is the actual speed and not that 200 km/h. I've mentioned this several times and even asked to get the Ego software so that it can at least reach 200 but that's not possible because it's a naked bike ... big BS because with my KTM 1290R Superduke I smoothly do the 270+ and that's naked too.

Now to answer the OP's question if he hasn't already left this forum  ... I changed the rear sprocket from a 44T to a 41T and the bike goes a real 208 km/h, I also have a 42T and then we are around 198 km/h. I have now left the 42T on it because it gives the best acceleration and still reaches almost 200 km/h.

In my view that has nothing to do with the legal stuff, let the speedo read too high but then do the limitation at 240 km/h so that it at least reaches the promised 200 because that was the only reason why I chose the Energica. With what I know now, I might as well have bought a Zero and saved some money  . And for those who are now going to comment on Zero and the charging, I don't care about fast charging I never charge on the road.

Peace
