Honma designed the D1 golf ball to optimize distance for golfers with a club head speed of under 90 MPH. The RB Soft Core has been reformulated and enlarged to help golfers achieve maximum ball speed. Additionally, the ionomer cover has been thinned out to enhance the ball’s feel, while the 368 dimples on the cover increase the height and carry distance of each shot. Despite being a two-piece ball, Honma has paid close attention to the finer details of the design to help maximize performance. This approach has helped the D1 become Japan’s top-selling golf ball. Those who have read our past reviews on Honma’s equipment know about their holistic design philosophy, which aims to get maximum performance from each club. That same philosophy is applied to the D1 golf ball.
