Frequently asked questions

When should I look for a used OEM TRX450R part instead of a new replacement part?

Look for a used OEM TRX450R part when you need a factory component and the teardown part's condition note describes something you can use. A used part is most practical when its exact fitment, completeness and noted condition all suit the repair. Choose a new replacement for a wear item or rebuild package you want fresh. In either case, check fitment for your exact year, make and model before you order.
