 The new bike used Degens' later development of a unit construction race-prepared Triumph engine, unlike the earlier models having a separate engine and gearbox.The new configuration won the 1970 Barcelona 24-hour race, reprising Degens' 1965 win.After this success, French motorcycle dealer Japauto commissioned Degens to build a bespoke race-frame for the still-new Honda CB750 four-cylinder engine that had been specially enlarged for racing to 900 cc.
