I forgot to say, that I had also contact with the people from Healtech for the speedohealer and sended them the complete wiring diagrams but they can not provide something to alter the speedo.

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.

What effect did this have on your Odometer, Wh/mi, and estimated range figures?

This subject comes up in all European bike forums. One should expect such with European bikes of any make.


FWIW, US made bikes, such as Harley and Zero have accurate speedometers. AFAIK, all the others read high, but how high varies, with the European bikes reading the highest at freeway speeds.

Honda generally read 10% over as well.

The tacho reading too high doesn't really bother me, but I do care that it affects the actual top speed 

As you say, my Harley's are almost bang-on with the GPS reading, and even my Honda Goldwing does ... to answer Cas   .

Morgan, to be honest I have no idea I've never looked into that because it doesn't interest me. I know that I can drive it to my parents +-55 km and there I put it on the charger for 2 to 3 hours and then I drive back home. Recharging is necessary because otherwise I can't get back and forth with a bit of decent power and speed.

What year GW?  I wonder if the fact that the GW was made in the USA (before year 2010) had something to do with that.

Thanks for the info, MoneyFor! I think I’ll drop down to a 42T on my SS9 as well*. Mentally subtracting the tens digit from the indicated speed is not a huge burden but I’d be glad not to have to do it anymore. People on the Energica FB group have expressed doubt that higher gearing would result in greater efficiency since the motor should be pretty efficient within a broad range of speeds, but I’ll report back on efficiency and odo accuracy if and when I make the gearing change.

I was thinking of getting this sprocket, assuming it would fit: https://www.revzilla.com/motorcycle/vortex-525-rear-sprocket-ducati-848-evo-998?sku_id=1266688

I was planning to pair it with a Regina HPE chain. I know, I know, “just get in the habit”! I’ve told myself I would clean and lube every chain-driven bike I’ve owned and I’ve performed a grand total of 0 cleanings and 0 lubings in 3 years and 4 bikes so HPE it is!

*assuming the SS9 also uses a 44T stock like the Ribelle, I haven’t been able to find this info but I can count the teeth manually

@flynnstig82r,

First I bought from the brand AFAM that Energica install as OEM but they did not make a 42T anymore, only 41T or 43T so I got the 41T.  I can not say that the sprocket from your link is oke but I can confirm that a sprocket for a Yamaha R1 / R6 fit, that is the one I have. Later on I bought from another brand ,  FE Sprockets, the 42T.

This is the size you need,

AFAM
