Team Saddlemen runs highly modified Harley-Davidson Road Glides.
Per MotoAmerica rules, redline is capped at 7000 rpm for these 131-cubic-inch Harley-Davidson engines, with their overhead valves, 'twin' air cooling (liquid-cooled exhaust valves), and 45-degree vee angle.
Saddlemen takes delivery of stock motorcycles, tears them down completely, and rebuilds them using lightweight carbon fiber components and bodywork, plus injecting a healthy dose of racing suspension and high-performance engine parts, all while keeping the class rules in mind.
