This model was a big hit in the 1970s as an entry-level sports bike for young people.
With its authentic style, it was able to be used for a wide range of purposes from commuting to school to touring.
It was able to be customized with a variety of optional parts to suit the rider's taste.

In September 1995, Mr. Tatsu Sakamoto set off on a round-the-world trip by bicycle, which had been his dream for many years.
He spent four years and three months, until December 1999, cycling some 55,000 km in 43 countries.
This bicycle carried all of his daily necessities and even spare tires.

This is a children's bicycle made under license from Harley-Davidson, the leading motorcycle manufacturer in the U.S.
It can make an engine exhaust sound and has a horn, and it even features a replica engine and gasoline tank, giving it the real feel of a motorcyle.

In Japan in the 1970s and 1980s, bicycle for boys that provided the rider with the feeling of riding a cart or motorcycle were popular.
This bicycle is equipped with a car-like shift lever, shining flasher lights and other devices that ticled the hearts of boys.

Who Is Shota Kawamoto?
Shota Kawamoto is one of Japan’s leading para-cyclists:
* born in 1996,
* competes in both road and track events,
* member of Team Japan at Rio 2016, Tokyo 2020, and Paris 2024.
At the Tokyo Paralympics he competed in:
* Men’s C2 3000 m Individual Pursuit
* Men’s C1–3 Time Trial
* road events as well.
One of the most significant moments of his career came in Tokyo:
* he set a world record in qualifying for the C2 individual pursuit before ultimately finishing fourth.
That likely explains why this specific bicycle was preserved and displayed at the Shimano Bicycle Museum.

The Bicycle Itself
The underlying machine is a highly modified Fuji carbon pursuit bike built for elite para-track competition.
Features include:
* full carbon monocoque aero frame,
* pursuit cockpit,
* fixed-gear drivetrain,
* full disc wheels,
* athlete-specific adaptive fitment.
But the most historically important feature is the prosthetic-interface support.

Why the Socket Matters
In one-legged track cycling, the rider faces major biomechanical problems:
Torque asymmetry
Only one leg supplies propulsion.
Pelvic instability
The rider can rock side-to-side under load.
Dead spots in cadence
Smooth circular pedaling becomes much harder.
Track-bike demands
Fixed-gear pursuit racing requires sustained cadence and stability at very high speeds.
The socket-like support behind the saddle likely helped:
* stabilize Kawamoto’s pelvis,
* support his residual limb,
* improve aerodynamic consistency,
* reduce lateral motion,
* and maintain efficient power transfer.
This transforms the bicycle into something closer to:
* a custom biomechanical system,
* rather than merely sports equipment.
