I have a 2017 & a 2018 MX with the junk 4cs front forks 😩. I just picked up two sets of 48AER FORKS. Does anyone know if the only difference is the front axles or are the bearings and races different as well? If it’s only the axles are they the same as the KTM axles?

I believe the axles are slightly longer, it may be close enough that a KTM axle would work, but I’d check with Liquid Performance first and see if they have the Alta axles. You would then also need the Alta front wheel spacers, I think Liquid has those as well.

Awesome thanks,
Ordered 2 axles this morning and 2 sets of spacers. Not sure if the spacers are for the 4CS or the 48AER. Part# 6800579-00 outer axle spacers?
