Our pall Dar over at Brass Balls Cycles started his Motorcycle career out build high end custom motorcycles for customers and celebrities. Over the years tired of getting utilizing even high end, price parts, he was tired of the lack of inadequate quality or poor fitments. He decided to start manufacturing his own parts! Dar designs his parts, then has them machined, anodized and self handles every shipment to ensure quality. This is one of the key reasons we love using Brass Balls Products, you'll never have to worry about a lack of quality, looks or fitment.
