I have googled and googled and read and watched until I am tired of looking. I am looking with someone from experience with upgrading the Foreman 400 to Front and rear disc. I am looking at the super ATV for the rear and see all kinds of issues and found someone on youtube who used a SnowMobile caliper on the super ATV kit and it works awesome. I am trying to figure out is there a way to upgrade to rear disc and adding a master cylinder and not losing reverse on the handlebar. Does anyone know of a left handled master cylinder that will work with reverse?
