The Las Vegas based Hiro Koiso Racing team made a big comeback on the salts of Bonneville. It succeeded in getting 3 new land speed records to include 2 AMA national records – 3000-MPS-PBG class 210.646 mph (339.001 km/h)*, 3000-MPS-PBG class 214.342 mph (344.950 km/h)* and a FIM world record of 214.653mph (345.450 km/h)* in 3000cc partially streamlined class.
New world record is 22 mph above the existing record. Hiro also made a single (non-record) pass of 198.941mph(320.164km/h) without fairing. Total of 15 records for the team have been set at BUB trials since 2008.
Since the vehicle suffered massive fire damage during 2012 race, it took the team all year to rebuild the entire motorcycle back to racing state. The bike is a highly modified 2006 Harley-Davidson DYNA powered by JIMS135 TwinCam Race engine modified by T-Man Performance. ProCharger B-1 supercharger force feeds air to the engine resulted in 271 hp to the rear tire.
Right on Hiro! Congratulations to you, your team and your family! Proud of all your efforts!
