8. Heavy Bus


I thought this thing looked familiar. Yours truly rode this very Yoshimura Hayabusa X1-R for a Motorcyclist magazine story around Willow Springs back before the turn of the century. Yoshimura gathered up a bunch of parts from its Suzuka 8-Hour effort to build a slightly milder bike for street use, but it still made 182 horses and 108 foot-pounds of torque. It’s packed with billet cams, 12.5:1 forged pistons, Carrillo 4340 rods, and makes peak torque at just 7500 rpm, which means it went around Willow – a really fast track – like some sort of NASA experimental craft. The Öhlins superbike-spec fork and shock were maybe not quite ready for the Busa’s heft, though, and I remember it being an eye-opening ride.

It also had an eye-opening parts manifest, about $50K worth of components by the time it was done, including a magnesium top triple clamp, Marchesini wheels, quick-change rear brake, etc. – and the Yosh people must’ve decided it just wasn’t going to be financially feasible, even at a time when we were all power-crazed roadrace maniacs. Where did it all go wrong? Redpath rescued the bike from the scrap heap, bless his heart. It lives in the front of the shop, next to a Mat Mladin GSX-R Superbike.

    “I really don’t know where he finds the time, but Red says this one will be completed in time for the Long Beach International Motorcycle Show in December, along with two other bikes.”

    Uh, the Long Beach International Motorcycle Show is in November this year.

  • I had a great time visiting Redpath’s shop, just amazing the stuff he has packed in there.
