Technical Sports One in Santee specializes in motorcycle road racing parts, stocking Honda HRC, Yamaha TZ-series, and Moriwaki competition components from its Prospect Avenue warehouse. The supplier operates alongside Motoworks Parts on the same stretch of Prospect, reinforcing the corridor's concentration of powersports parts sourcing for East County riders. Inventory covers VHM crankshafts, Vertex and Wossner pistons, Brembo brake systems, Marchesini and Marvic forged wheels, and Battle Factory paddock equipment for road-race applications. TSO ships nationally from the same Prospect Avenue auto-supply corridor where Autoworks Parts handles general automotive components, though TSO's catalog focuses exclusively on competition-grade motorcycle hardware. The parts library cross-references OEM Honda RS125, RS250, NSR500, and Yamaha TZ125 and TZ250 part numbers against aftermarket equivalents from Sebimoto, Tyga Performance, and Zero Gravity for full fairing-to-sprocket race builds.
