I sponser a guy. He rides my Honda CRF100. His parents have a Yamaha YZ85 for him. I looked for a smart kid that could ride. He had to have control over temper tantrams, he needed to be kean and eager (riding a 4 stroke against 85's), he had to be willing to listen and put it into practice, he had to be positive, polite, no big head, good presentation, clean and tidy gear etc, willing to look after the bike a bit, supportive parents but not pushy and overbearing, was MX mad but had a life outside of MX and a reasonable resume. I found a 12 yo that fitted the bill and I am very happy with him. He gets a fully maintained bike, free parts, help with gear and entries paid. I found him. Thats the biggest hint. I FOUND him so think about what YOU can do for the sponser and how you present yourself in front of others. Remember a lot of kids think a free sticker is sponsership. I like to think of it a killer deals on bikes, good prices on parts, helpful dealer, good trade connections and either me or my riders saying thanks and meaning it and that includes my boy. You might already be doing / getting that.
