Montgomery Motorsports continues to lead the way in ultimate sportbike performance, teaming with Karl Gunter to set a new all-time speed marks for an all-motor sportbike.
Gunter’s 2005 Carpenter Racing-equipped Hayabusa ran 227.3 mph at the East Coast Timing Association (ECTA) land speed racing event at the “Ohio Mile” in Wilmington, OH. Gunter stated that the time was the fastest ever recorded for naturally-aspirated motorcycle over a mile course.
The bike was driven by LSR veteran Zach Millholland, brother of former AMA/Dragbike SuperSport standout Chad Millholland.
A week later at a Loring Timing Association event in Maine, Gunter’s bike ran a stunning 235.7 mph in the 1.5 mile course with rookie LSR rider Colt Bateman at the controls. Bateman also recorded unofficial marks of 230.1 mph in the mile and 208 mph in the half-mile.
The bike features Carpenter Racing’s “Gloves Off” 290+ hp, 1635 cc package featuring the 4-into-1 Megaphone race exhaust system. This is the highest performance package you can get for an all-motor Hayabusa.
“Without the Montgomery Motorsports Carbon Fiber Air Box, we could have not sucked in all of that air”, said Zack Millholland.
“Montgomery Motorsports engineering and design allowed us to get these records,” said Gunter. “Montgomery Motorsports builds the best carbon air box on the planet. The HP gains and the light weight is a must have when you are going after world records. The best decision I made was to add the air box to compliment Bob Carpenter’s engine work.”
The Hayabusa, dubbed “Greenie” is painted as a tribute to Gunter’s Kawasaki background. Although it is naturally-aspirated, it runs in the MPS/F 1650 class which allows nitrous oxide injection.
