 As with all the modular Triumphs, the T309 series Speed Triple had a very large single steel tube backbone frame, and used the engine as a stressed member.Forks were 43mm multi-adjustable Kayaba units and the same Japanese firm's shock could be set for preload and rebound damping.Kayaba (now known as KYB) had had a special relationship with Hinckley Triumph from its earliest days.
