At the annual Bonneville Motorcycle Speed Trials AMA Land Speed Grand Championship, Hiro Koiso – builder and rider – set three new land speed records on a 2006 FXD-I based race bike. The JIMS 135″ TWIN-CAM engine was topped off with billet cylinder heads from T-Man Performance. A C1-R ProCharger was custom fit for assaulting the Salt, the bike boasting 378 hp at the rear wheel.

” We had a rough start on preparing for 2017 racing season since the high speed crash of 2016 which destroyed the majority of equipments and required 4 months of recovery for Koiso. For 2017 the team focused on going after land speed record in the category non-streamlined.”

The new chassis configuration worked flawlessly. and the team managed to set a new record (pending ratification) The team managed to set new pending record (pending ratification) of 216.818mph in 3000 A-PBG class over 177.539mph previous record held by Wink Eller since 2013.

Later in the week, the team upped the speed to 226.100mph in AMA 3000 A-PBF class and a new FIM world record of 227.236 mph (365.700km/h) in Group A1, Division A, Type II, Class 2500cc.

    Congratulations to Hiro and the team! Breaking the A-PBG class record by almost 40mph is insane.

    Hiro and his family & crew are aces in my book.
    I admire people like him and others with similar drive.
    Their landspeed program is much more than an all too often seen bucket list type of thing,
    and or a video opportunity.
    Hiro Koiso and his team return every year bringing something new, improved, AND FASTER!
    That’s what motorcycle landspeed is all about.
    Congratulations to everyone involved. 🙂

    You are the man Hiro! Some day we hope to get our bike over 200 mph but I don’t think we could ever do the kind of speeds you have achieved!
