i dont think its very easy to make a living from trials riding. i dont think people get money from the sale of a signature frame i think its just they get there name out there. i have heard of a few people getting a small amount of money off sponsors but never enough to live on. the best way to earn money is with shows but there are already good riders out there with shows so business would be hard compeating against the relentless tour and the clan plus loads more you would have to be something special.
