Double Dog Moto Composite Exoskeleton Race Tails Receive AMA Pro Homologation

Fresh from homologation of their first product for AMA unique 'expansion chamber' exhausts Double Dog Moto confirmed approval from the AMA for their world-first Composite Exoskeleton™ tails, which replace regular metal subframes and cowlings with one structural monocoque.

Double Dog Moto developed these non-carbon composite monocoques specifically to comply with AMA regulations, which banned carbon fiber since the 2009 season. After a long and intensive R&D process, final approval was announced by the AMA after the final stage of inspection during the Indianapolis Dealer Expo last weekend.

Said President and chief engineer, Mark Henry: "We are very excited to make this announcement and also very proud of the expertise we have developed in this specialized industry here in the USA. It's very satisfying after all the hard work to launch a world-first product that is not only AMA legal, but affordable for the club racer and street rider. We'll soon be making an official announcement with quotes from some of the top AMA Superbike and Daytona Sportbike racers about results of their own tests. That should raise a few 'old guard' eyebrows!"

Using the composite expertise they developed in layering metal and carbon fiber for extreme strength/weight ratios, the Double Dog Moto engineers are now applying that technology to more economical non-carbon composite monocoques, using glass fiber and Kevlar in place of carbon fiber. With much the same benefits as the Carbon ExoskeletonTM monocoques, the new Composite ExoskeletonTM monocoques are only a little heavier and less stiff, at around half the cost.

Available now for Ducati, RSV4, S1000RR, Yamaha R1, and soon GSX-R1000 and CBR1000RR, the Double Dog Moto Composite ExoskeletonTM tails are price competitive with regular metal subframes plus cowlings.

Said President and chief engineer, Mark Henry: "Apart from the lighter weight and tougher 'crashability', high level racers love the increased chassis feedback from a tail that is incredibly stiff, with basically zero flex to filter out vital information. We predict a lot of AMA teams will switch to the Composite Exoskeleton tails once word gets out about test results, and hopefully that will translate into strong interest from club racers and street riders by the end of 2011. It's going to be an exciting year for everyone, including our competition!"

Double Dog Moto was founded in San Francisco in July 2009 by mechanical engineer and AFM road racer Mark Henry to commercialize his innovations in structural carbon fiber and high performance Titanium exhaust systems. Sales have grown rapidly, both domestically and internationally, and Double Dog Moto products have been instrumental in the success of a number of championship winning racers.
