A dyno shop built around the bikes we actually ride.

Alter’d Motorsports is a north Dallas dyno and performance shop on Whitlock Lane in Carrollton, a few turns off I-35E and the Bush Turnpike. Sportbike and superbike performance is the whole point of the place, with Harley-Davidson and Indian V-twins on the same rollers and the same schedule.

Every tune starts on the rollers with a baseline pull and ends with a printed sheet. Every service follows the factory schedule and gets a straight answer about what is due now and what can wait. If a part will not make a difference you can feel, we will tell you before you buy it.

The shop sees BMW, Ducati, Yamaha, Suzuki, Honda, Kawasaki, Aprilia, KTM and Triumph daily, plus metric cruisers for service. Track riders, commuters and weekend canyon riders all get the same dyno, the same techs and the same sheet. The Art of Excellence.
