Stock Hypermotard - 870mm Hyper SP - 890mm Hyperstrada - 850mm Only the SP has fully adjustable forks, the other two have no adjustment on their forks. The SP has a fully adjustable Ohlins rear shock, the other two have a Sachs shock only adjustable for preload and rebound. The Stradas shock preload is hydraulically adjustable.
