Speed Error after 41T change

jyli19 · Sep 16, 2013

Got the 41T rear sprocket for a 2012 Base Panigale. Noticed my speed is higher on the dash then actual. Is this normal, should ECU automatically compensate for 41T sprocket change?

Thanks

i have the 41 sprocket and my speed is fine. garmin and speedometer were the same. no issues. do you have the most current upmap?

The bike will show 3-7% faster than actual speed, approx from the factory. Did you measure the speed before the mod?

The speed sensor is on the front wheel, the speed shouldn't be affected with sprocket change unless you change front tire size.

do a back to back GPS measurement.

sprockets won't change speedos.

you will notice it pulling harder though, bringing you faster up to speed

I agree with everyone here, I have also done the 41T swap, and my speedo still reads accurately. May be a separate issue with your bike.

i changed and my speed has not been accurate neither before or after. it's never been accurate, speedo always read too high after about 60+.

So if the speedo is correct, then the bike must be running that much better. I am pulling triple digits and feels like i am doing 80mph. Woohoo!!! This is awesome.

Thanks y'all
