No matter what you need for your machine, the St. Hilaire Motorsports team is here to help.

Founded in 2009, St. Hilaire Motorsports has become one of New Hampshire’s trusted destinations for powersports vehicles, trailers, parts, service, accessories, and riding gear. Our team brings more than 100 years of combined industry experience. As riders and racers ourselves, we understand what customers expect both on and off the trail.

In April 2025, we expanded our dealership group through the acquisition of Amherst Motorsports, adding our Milford location. Today, we proudly serve customers from two convenient locations.
