Progressive Suspension 428 Series Monoshock

Progressive Suspension has an all-new shock line called the 428 Series monoshock, which was designed specifically for smaller-bore sportbikes. The 428 incorporates proper spring rates and specifically tuned deflective disc dampers combined with a gas charge to prevent oil foaming. Each 428 is wrapped in an all-aluminum, threaded body for fine-tuning to match your riding style and weight for a smoother ride, better handling and improved bottoming control. The 428 Series monoshock ($349.95) is available in stock length as well as 1-inch lowered. Initial fitment includes the Kawasaki Ninja 650 and will soon expand to other bikes.
