Yamaha drag racers recently set a pair of new records, both aboard 4-stroke powerplants. John Wheelock set a new grass drag record of 4.073 seconds in 500 feet at the COSDRA Top Gun Shootout. Team Simon’s CPR modified RX-1 became the first snowmobile ever to break into the seven-second club with an incredible 1/4-mile asphalt record of 7.97 seconds at 170 mph.
