Tim Bemisderfer aka "Big'un"

Tim "Bigs" Bemisderfer

Tim has spent his entire life in and around the motorcycle industry. Since his dad signed him up for his first race, he's been hooked, competing in nearly every discipline of racing including motocross, flat track, hare scrambles, super moto, and of course road racing. In that time, Tim was able to establish himself as a perennial front runner, amassing several national and regional titles with WERA, CCS, and ASRA.

Recently, Tim has been passing his knowledge and experience on to other riders through set up assistance, motor builds, coaching, and mentoring. Tim was honored to play an integral role in the development of US made Dunlops and was the first person to compete in a professional AMA race on US made Dunlop slicks. Tim is excited to expand his long standing relationship with Dunlop and assist riders in optimizing their bikes for Dunlop tires.
