Additional dyno tests done at the request of readers and Yamaha owners alarmed by an almost-20-horsepower spread between Roadracing World's 2001 Yamaha YZF-R1 test bike and Roadracing World's 2001 Suzuki GSX-R1000 test bike did not reduce the power gap.
Substituting one YZF-R1 for another and redoing the tests on the White Brothers Model 200 Dynojet dyno in Yorba Linda, California on Friday, January 12 resulted in the same spread, with almost identical horsepower figures to those seen in the first set of dyno runs.
Running both bikes on North County Hyper Sports' Model 150 Dynojet dyno in Oceanside, California on Saturday, January 13 increased the readings for each bike by about six horsepower, but did not close the power gap. On the Hyper Sports dyno, the Yamaha made about 130 horsepower and the Suzuki made about 150 horsepower.
