Modern Vespa

Hi. I need a rear ABS sensor for my 2015 GTS. Only a front one seems to be available in all the usual places. I think someone here said that the front and rear are the same. Is that the case?

why are you replacing it? are you sure it's damaged and not just incorrectly installed or a bent abs tone wheel after a tire change?

also be careful, in 2016 the rear sensor changed. Don't trust the year isntead check the cable on your parts vs these two pictures

I've had it at a Piaggio dealer because of intermittent issues with ABS and ASR lights coming on. The diagnostics pointed to issues with the rear sensor. They've asked me to get the part as they can't find it. I remember changing one before and the plug matches the link you sent to the ABS sensor 2016 on but SIP website says that will not fit my scooter. I know the plug on the speed sensor link you sent does not match. The scooter was registered in 2015 but was likely built in 2014.

I posted two, not one. And which *cable* like the same.

One is "speed sensor 2014 to 2016" and the other is "abs sensor 2016-". The speed sensor has wrong plug on it and the ABS sensor SIP site says it won't fit my model.

I think it's this one.

I had it confirmed by SIP who confirmed with Piaggio that this sensor does front and rear on 2014-2016.
