What we do

Tuned on the rollers, not on a forum.

Every tune starts with a baseline pull and ends with a printed before-and-after sheet. No guesswork, no generic maps.

Scheduled service and the repairs that keep a performance bike performing.

From a tired top end to a built motor, finished on the dyno where it belongs.

“Best motorcycle shop in Dallas. Took my bike in to get my front forks serviced. Also got a tune for my FZ-09. Alex and his team are the best. Customer service was impeccable! Also picked up a matching helmet.”

“Altered Motorsports and their team are amazing. I moved to Texas and fell in love with sport bikes after riding a Harley for years. I needed a mechanic who can customize my bike with a good tune, paint and carbon fiber.”
