About Diamond Motor Sports
Fueling Your Passion for Adventure
Whether you like conquering the open road, hitting some dirt paths or cruising over waves, you can fuel your passion for adventure at Diamond Motor Sports! We've been helping Delaware powersports fans find, maintain, and customize their motorcycle, dirt bikes, ATVs, UTVs and PWC for more than 50 years, and we're committed to letting every rider from Dover, Smyrna, Milford, Frederica and beyond fully live out their dreams.
If you're in the market for a new or used Can-Am®, Honda®, KYMCO, Kawasaki or Yamaha motorcycle or dirt bike, we have everything you need at Diamond Motorsports. If you're looking to go off-roading in an ATV or UTVs or want to hit the water in a PWC, we can oblige you there, too. And when you need back-up power check out our power equipment so you're never stuck without power.
