The Progressive Suspension 412 Series shocks are simply the best value shock on the market today. The 412s simple, durable design means they will be an improvement to your motorcycle's suspension performance for as long as you are riding it. The double-wall steel body construction with nitrogen charged, multi-staged velocity sensitive valving gives you smooth, consistent damping. A five position cam style preload adjuster lets you dial in your ride whether you're a standard rider or heavy loader.
Heavy-Duty is recommended for bikes that are operated at or near the manufacturer's maximum load rating over 50% of the time. Price per pair.
Maintenance schedule: Honda recommends checking your suspension every 8000 miles or 12800 km.
