Company History

TM Racing is a racer’s boutique: engines and frames developed in-house, suspension and brakes at the top shelf, and customization down to gearbox ratios. The bikes feel taut and immediate, rewarding skilled riders with lap-time precision. Low volumes mean meticulous assembly and rapid updates from factory racing to customer bikes. TM’s identity is purity—no fluff, just competitive hardware that speaks vividly through the pegs and bars.
