    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. 🙂
