Have you tried to hit the override! Button. Not sure if you have one ?

Sorry but forgot to say it's a 500es model

[2015 Z Force 800 53/Trail EPS]

You say it had plenty of RPMs so its not engine. And you day it's fine on the flat so..that leaves a traction issue. If the tires are just spinning that says...you need a different tire.

Jogon30, by the way I found out that override switch on the Z8s only work on the diff-loc limiter. Has no effect of the reverse limitor...at least not on mine.
