Built by Magnum Opus Custom Bikes, (I’ve featured XV750 build and a CB750 build of theirs in the past), this Kawi turbo was first revealed to the public last weekend at the Handbuilt Show.

The bike started as a ’78 KZ650 that was bumped up to 830cc courtesy of a period MTC big bore kit. On the seller’s site, you’ll find a gallery that shows some of the build, which includes a American Turbo Pak kit – you may remember that name as they supplied the turbos for the Z1R-TC.

There’s obviously plenty of other work done, but the result is that at low boost (around 5 psi) the motor puts down 90 horsepower on 91 octane. After break-in, you could double the boost and run higher octane to see between 105-115 horsepower. The turbo starts spooling around 5,000 rpm, and I’d love to see a video of this on the prowl.
