Shopper Award

High-quality O.E.M style replacement for Harley-Davidson.

In 1982, the New England Motor Parts Company (NEMPCO) introduced the Twin Power line of high quality replacement motor parts for dealers. Under the watchful eye of Jim Thompson, Charlie Hadayia Sr. and others, the Twin Power line became known for quality and performance at a fair price.

For more than 30 years since, Twin Power has remained a leader in aftermarket parts and accessories for American V-Twin bikes. The Twin Power line now covers everything from yesterday's old school to tomorrow's classics. From pistons for Ironhead Sportsters to high-tech lithium ion batteries, we have more performance parts for more applications than ever, tested in independent testing labs to ensure that they fit and work like they should.

Through it all, our philosophy has remained true: Twin Power is a brand by bikers, for bikers. If we won't run it on our own rides, we won't sell it to you.
