Advance Motorsports in Chula Vista services all motorcycle makes and model years from its Broadway workshop at the K Street intersection, covering Harley-Davidson, Yamaha, Honda, KTM, and off-brand platforms. Complete antique and collector-bike restorations include frame-off disassembly, in-house TIG welding, and full repaint — the same caliber of powersport craftsmanship offered on the sales side at Del Amo Motorsports of South Bay. The in-house machine shop handles cylinder boring, crankshaft truing, valve-seat cutting, and broken-bolt extraction without outsourcing to third-party machinists. Powder-coating services refinish frames, swingarms, and engine covers in custom colors and textures, and the paint booth handles tank repair, ding removal, and full-chrome restoration. ATV, UTV, and motor-scooter platforms round out the repair menu alongside parts sourcing through the same OEM and aftermarket channels stocked at Cycle Gear on the retail side.
