“As a young teenage racer Bobby Sirkegian had it all, his Triumph drag bikes were tuned and sponsored by his father’s Los Angeles dealership. Success was almost immediate for Bobby, with his quick reflexes and superior power-to-weight ratio, and a helpful hand from his dad to balance the bike behind the start line!!
Despite Bobby’s young age his drag racing abilities meant Bonneville officials gave him special permission to run at Bonneville Speed Week in 1953. In the 650cc class Bobby lined up on a bike which was built along the same lines as his drag racers. The Bike had over bored cylinders and a big-bearing crankshaft with special-grind Iskenderian camshafts and lifters, and lightened, narrowed timing gears. A 3-gallon fuel tank from Triumph’s 3T model carried enough gas for the salt flats speed runs.
Family friend Rollie Free gave Sirkegian a pair of his 3×20-inch Avon file tread rear tires, which had been especially developed for high speed work at Bonneville. Although Bobby’s 122-mph pass on a 650 didn’t set any class records he was awarded for being the youngest drag racing gun ever on the Bonneville Salt Flats” – source Bonhams via Motorivista
