1982 Yamaha 650 Secca Turbo. This Was One Of My First "High Tech" Toys. |

| The Bike Was Really Advanced For Its Time. It Was The First Of The So Called "Crotch-Rockets", Using A High Frequency Microphone Between Cylinders #2 And #4 To Detect Pre-Ignition While Advancing The Timing During Full Throttle. If Preignition Was Detected It Would Back Off The Timing Advance. Oh And Did I Mention It Was Turbo-Charged? | ||||||||
