Lee Motorsports Shipping Information

At Lee Motorsports, we are committed to providing fast, reliable, and transparent shipping for our customers. Please review the information below to understand how your order will be processed and delivered.

Product Assembly
Lance, SYM, Scootstar, MotoTec, and Trailmaster powersports vehicles are typically shipped non-assembled unless otherwise noted. This helps protect the machine during transit and ensures it arrives safely and in proper condition.

Performance Parts & Accessories
Most in-stock performance parts and accessories ship within one business day of your order being placed. Our goal is to get your parts on the road quickly so you can get back to building and racing without unnecessary delays.

Warehouse Network
Lee Motorsports ships from a nationwide network of distribution warehouses across the lower 48 United States. Some products ship directly from our main facility, while others ship from regional warehouses to reduce transit times and improve delivery efficiency.

Engines & Transmissions
Engines and transmissions are shipped via LTL freight directly from our suppliers. Lift-gate delivery is typically included to assist with unloading at residential or commercial locations. Transit times may vary depending on your location, and freight shipments may require a delivery appointment.

Race Fuel - Pickup & Local Delivery Only
Due to hazardous material shipping restrictions and the high cost of freight transport, race fuel is not available for standard shipping. Fuel Factory race fuels are available for local pickup at Lee Motorsports or by pre-arranged local delivery. Trackside delivery may also be available for select racing events. Please contact us in advance to schedule fuel pickup or delivery arrangements.
