Having already achieved 126 mph (203 km/h) on an unfaired bike, Kolb has applied some new streamline bodywork and made some alteration to the bike's geometry.
The custom-framed land speed racer features radically altered geometry and a 98-inch wheelbase that allows the rider and engine to fit between the wheels. In order to achieve the feat, Scott had to modify the bike with some additional features, Hell for Leather magazine reported.
He stretched the bike by more than 40 inches, and replaced the non-aerodynamic radiator with a radically streamlined fairing and also water-to-water chillers for maximum performance.
The Martin Eurosports-built 1996 Honda RS125 engine produces 41 bhp at sea level, meaning power is probably reduced to about 36bhp in Utah, HfL says.
However, not everything ran smoothly. “Given the bike is a two stroke that is held wide open for over 75 seconds, every nut and bolt has to be either safety wired or given a generous helping of Loctite,” Kolb was quoted as saying by the aforementioned source. “The hub center assembly in my haste to complete the bike did not get a generous helping of loctite and what you see is a bolt that had backed its way out.”
“I was in over-rev through the timed mile and could have geared for 155MPH if I had one more day of competition. Next year!” Kolb said.
