Performance upgrades are truly the bread and butter for our shop, as they enhance the overall experience of riding.
First, we begin with a thorough consultation to understand your individual preferences and requirements, allowing us to provide our best recommendations for engine upgrades that will best suit your unique riding style.
Our shop is fully equipped with a state-of-the-art dyno tune, which is essential for dialing in your fuel injection system to achieve optimal performance. In addition, we utilize in house machinery that allows us to bore cylinders and install a cam upgrade kit with the utmost precision, ensuring that everything functions as well as it possibly could for your motorcycle.
We don’t just improve your bike’s engine sound; we also install audio systems to enhance your audio experience. Our skilled team integrates high-quality sound systems that fit your bike perfectly. We proudly work with Rockford Audio, a leading name in the industry, to provide you with the best setup.
To effectively maintain your engine, we encourage you to bring it in for regular service appointments. We are pleased to offer oil changes on Saturdays, available on a first-come, first-served basis, to help keep your engine running at its best. It is recommended that you change your oil every 2,500 miles to ensure optimal performance and efficiency.
Every 5,000 miles, it is important to replace the engine oil as well as the oil in both the primary and transmission systems. During the 5,000-mile service, we will conduct a thorough and detailed 20-point inspection, along with necessary adjustments, to help prolong the life of your bike's various parts and enhance its overall performance.
We take great pride in our exceptional high-resolution detailing on motorcycles, ensuring that every intricate feature of your bike is beautifully showcased and highlighted to perfection. If you are planning on bringing your bike into the shop for service, consider adding a thorough detailing to your visit while you are here. It’s a great opportunity to have your motorcycle looking its absolute best!
When the rubber finally hits the road, you want nothing but the very best tires for your vehicle. J & D CYCLES proudly offers a wide selection of high-quality new tires and has established partnerships with premium brands to provide our clients with the best possible deals in the city. Don't hesitate to call us for competitive pricing and to explore our comprehensive range of options.
We are an inspection station for motorcycles and scooter in the state of Massachusetts. Bring $15 and your current registration, and we'll handle everything else.

His son, Domenic Jr., has become interested in Harley electronics, following in his father’s footsteps, and is now a certified Rockford Audio Specialist after starting at the shop.
