A rare 1988 single-cylinder race bike, the Ikuzawa Harris TH1R, has been listed at Iconic Motorbike Auctions in the US. Its frame was built by Britain's Harris, paired with a Honda RS600D flat-track engine producing 61hp at 7,000rpm. The owner is 83-year-old former racer Tetsu Ikuzawa, whose team won the Suzuka 8 Hours endurance race in 1989.

The Honda RS600D is a flat-track engine, so it's the kind where you feel the throttle response straight through your fingertips. 61hp at 7,000rpm might sound peaky on paper, but from what I've seen trackside, a single-cylinder like this puts the rider's skill on full display from corner entry to exit. Just seeing the name Tetsu Ikuzawa attached to it gets my blood up.

Why single-cylinder for a race bike?

It's all about weight and handling over raw power.

Curious how high bidding goes but it'll probably land way out of reach for regular folks.

British frame + Japanese engine, wasn't that a fairly common combo back then?

61hp from an RS600D is solid output for a flat-track engine.

Ikuzawa Toru—still a legend at 83.

Right, and it's from the Suzuka 8 Hours-winning team—wild history.
