Cfmoto is aware of this issue and refuse to do a recall. They are using plastic weight sliders in the clutch and they will end up melting even as soon as 300km. They will blame tire size of any mortification you do but the truth of the matter they should not be using plastic in a high heat clutch. My machine has only 700km and 2 of my buddies are having the same issue at only 300km with factory tires. They blamed the belt getting dirty. This is a serious matter. They should do a recall on all cfmotos that use these plastic sliders that hold the weights in the clutch. This could potentially cause harm even possible death if someone is driving when the lockup occurs. I was going 50km on a road and it almost caused me to crash. Cfmoto head office does not appear to be doing anything to help everyone. they wait until you have an issue and decide on a case by case to approve or reject the repair. I would like everyone that currently drives a Cfomot zforce 800, 1000, 950 sport to start a class action suit.
