Apologies if this is in wrong section or pretty simple to answer, totally new to it all. I've got a 2015 CRF250L but the rear brake is so hard to feel compared to my partner's bike and my brother's. I always end up dragging it and making the back wheel slide because I can't really feel it. Sure, I can feel it applied somewhat but barely compared to other bikes and I think it'll be pretty dangerous. Is there a way to adjust it easily or is it best to take it to someone?
