Motorcycle and ATV Expert


Our motorcycle and ATV experts are enthusiasts who combine their engineering and industry knowledge of motorcycles and ATVs with hands-on experience. We evaluate issues of operator actions, product defects, tire failures, roadway issues and improper maintenance to reconstruct a crash and determine causation.

Our experts have been operating motorcycles and ATV’s longer than they have been operating automobiles and can assemble them from scratch. We have built and modified bikes for cross-country racing, including engine-building, chassis-tuning, maintenance and failure diagnosis. Professionally, our experts have performed testing and evaluations for major manufacturers and government agencies and completed Motorcycle Safety Foundation-sponsored training. Many are active members of national motorcycle associations, including serving as technical presenters with the American Motorcyclist Association.
