Bonneville Speed Trials. Hiro Koiso Racing Set 2 New Land Speed Records.

Published by Cyril Huze September 3rd, 2014 in Editorial.

Hiro1Hiro2Difficult conditions this year on the Bonneville Salts. Strong wind and rain the week before the event and some more during the Speed Trials, meaning racers working tirelessly to dial their bikes and patiently waiting and waiting during hours to find the right window of time for a land speed record tentative. Among those who succeeded (I will announce others), Hiro Koiso setting two new records on a 2006 FXD based Harley-Davidson, one at 211.080 mph (339.700km/h) in the 3000APS-PBG Class, and one at 211.0325 mph* (339.623km/h) in the 3000APS-PBF class. The bike was powered by JIMS135 Twin-Cam engine modified by T-Man Performance fit with ProCharger. Producing over 300HP at the rear wheel. Hiro Koiso did also a one-way record pass at 221.000mph (355.665km/h) Hiro Koiso Racing. (Photography Taka Masui for Cyril Huze)
