Also in '89 began working with the small factory team at Triumph rationalizing existing models based on a very successful modular design plan, including the concept and styling of the unfaired Trident triples, all in time for the 1990 IFMA launch. Continued to work with Triumph as principal stylists and model makers for virtually all the machines introduced before 2006. Models included the Tigers, the Thunderbird and Thunderbird Sport, the Trophy (with luggage system), the Sprints, the T595/955 Daytona (frame included), and the concept and styling of the Speed Triple. Then came the new Bonnneville, the Bonneville America, the Thruxton and the Scrambler, a couple of secret ones and the concept and styling of the Rocket Three.
