Five new world land speed records have been set on Triumph motorcycles during the 2009 BUB Bonneville Speed Trials at the world famous Bonneville Salt Flats. British racing journalist Alan Cathcart of Denemoore, Claverdon, UK, teamed up with South Bay Triumph owner Matt Capri of Lomita, Calif., to set the records with the iconic British motorcycle at its namesake race course.

Cathcart rode a street-legal Triumph Thruxton to three records in the FIM's 1000cc Normally-Aspirated Twin-Cylinder Unstreamlined class; The Thruxton was prepared by Capri. The duo set new two-way FIM World Records for the flying mile at 152.678 mph and the flying kilometer at 152.770 mph as well as a best one-way speed of 153.150 mph.

Cathcart also rode Capri's turbocharged 2005 modified Bonneville to two more FIM World Records for the 1000cc Forced Induction Twin-Cylinder Unstreamlined class by turning in a two-way speed of 165.405 mph for the flying mile and 165.672 mph for the flying kilometer. The bike's best one-way speed was 171.624 mph. The mile speed also qualifies for a new AMA record.

"We've been coming to Bonneville since 2007 in preparation for this, the Bonneville model's 50th birthday year," Cathcart says. "Breaking the 150 mph barrier with the standard bike was always our main objective, and when the FIM established the new Twin-Cylinder category for Speed Records, it was great that we could claim official World Records by doing so. Matt Capri is a genius when it comes to tuning bikes for the Salt, at 4,400 feet in altitude. To set two more World marks with the Turbo, which he's developed almost as an afterthought and has spent very little time on, is just the icing on the cake. For sure this is a 180 mph-plus motorcycle with more development in its present naked guise, and with a fairing it'll go much faster. Maybe we'll be back next year to try to join the 200 mph Club with it!"

"This record holding bike started as an '05 Bonneville wreck with a 790 engine. It has been modified extensively with the swingarm from a Speedmaster, a turbocharger, custom made throttle bodies with 4 injectors, custom made plumbing and brackets, 17" alloy wheels, and custom metal work. The engine has been stroked to 988 cc and generates an astounding 232 hp at the rear wheel with only 14lbs of boost."
