Z1 Beater! A Honda CB400F Tuned for the Track
It’s great news for custom moto fans, but for builders, it makes it harder to stand out in the crowd. But walking around Mama Tried earlier this year, it was impossible to take my eyes off this track-inspired Honda CB400F.
“This 1975 Honda CB400F started life as a roached-out roller, with a motor rotting away in the Arizona Sun,” he tells us. “I always loved the 400Fs that Kaz Yoshima used to campaign, known as the Z1 beaters. So the motor was rebuilt around how he used to set them up.”
There’s also a Webco cam with an adjustable cam gear inside, the crank’s been lightened and balanced, and the rods have been shot peened. Other upgrades include a Dyna ignition and coils, and an oil cooler to keep temperatures down.
He’s done a number on the CB400F frame too. The subframe’s been shortened, the kickstand relocated, and the exhaust mount tweaked.
Then there’s that alloy swing arm, sourced from Framecrafters. It comes with adjustable shock mounts and two-position axle adjusters, giving Shawn control over his setup. It’s hooked up to a pair of custom built Racetech G3 shocks and the stock forks have been upgraded with Racetech Gold internals with preload adjusters.
Small billeted parts lurk everywhere. There’s a 20 mm race axle, custom lower triple tree, a new brake stay, new motor mounts and a cam chain adjuster. You’ll also spot finned engine covers, and a whole bunch of drilled out bits.
Though the front of the CB400F is dominated by an alloy number board, there’s an LED from Clearwater mounted lower down by the left side fork leg. Despite its compact size, it’s equipped with adjustable high and low beams.
For the bodywork, Shawn kept the CB400F’s tank, but built a new tail section. He started with a foam mold, then shaped it with six layers of fiberglass. The front fender and rear hugger are carbon fiber, made by Tannermatic.
Dane Utech handled the seat upholstery, combining Alcantara, leather and perforated leather with gold stitching. And everything that hasn’t been treated or painted is aluminum.
Now that sounds like fun for all concerned—unless, perhaps, you’re on a Kwaka and trying to keep up.
