A top speed of 182 mph was achieved by MotoAmerica’s King of the Baggers at Daytona. (Harley-Davidson/)
The bare bones of Daytona’s two six-lap Baggers races are that Kyle Wyman (Factory Harley-Davidson Race Team) won them both from the chicane on the last lap, and that second in both cases was fast learner Troy Herfoss on an S&S factory Indian. Herfoss is fresh off his third Australian Superbike championship and had never seen Daytona.
Some things have changed since last season, but let’s review by stating that this class has a minimum weight of 620 pounds. The hybrid-cooled Harley is allowed 131 cubes and the Indian 112, with a rev limit of 7,000 for the Milwaukee giant and 7,700 for the Indian. Horsepower? Maybe close to 185. The fastest top-speed number this weekend was 182 mph. Last year’s quickest lap was a 1:50.563, but this year Herfoss cranked out a 1:49.987.

These motorcycles weave. Not on the banking, but when lifting up from a corner or during direction changes, and riders are able to mostly ignore it. Although the weave makes some maneuvers spectacular, be sure the technicians and engineers are working on this.
