[1. What is the definition of a classic motorcycle?]
The term "classic car" (kyusha), which is used not only for motorcycles but also for automobiles, has an ambiguous definition, but in most cases, it refers to models that have been on the market for 20 to 30 years.
However, this does not apply to models that are still being sold, and in many cases, "classic car" is defined as models that are no longer in production.
However, this does not apply to models that are still being sold, and in many cases, "classic car" is defined as models that are no longer in production.

The word "restore" means "to bring back to its original state" or "to revive." With the latest models, advances in materials and construction may allow them to be ridden for a longer period compared to older models.
On the other hand, older models referred to as "classic cars" (kyusha) often have deteriorated exteriors such as paint and seats, as well as carburetors and engine interiors, even if they haven't been damaged by accidents. Restoration means repairing or replacing such parts to bring them back to their original condition.
Also, unlike customization, restoration aims to bring the classic motorcycle as close as possible to its original stock appearance. It's important to remember that in this regard, it also differs in meaning from an overhaul, which refers to disassembly, cleaning, and repair.

[3. Benefits of restoring a retro motorcycle]
Classic motorcycles that need restoration have many enthusiastic fans. This is because retro motorcycles have a unique charm in their engines and designs. Restoration is a laborious process, but that is precisely its advantage.
By restoring and riding a classic motorcycle, you can obtain a bike with "good old design" that is different from the latest models in terms of performance and design.
Of course, new models also feature trendy exterior designs and high-performance specifications.
However, by restoring and riding a retro classic model, you can enjoy a biker life that is different from others.

[4. How much does restoration cost?]
There are various restoration processes, ranging from partial restorations to those that involve disassembling the frame.
The price varies greatly depending on the shop, and also fluctuates based on the availability of parts. Therefore, it is impossible to definitively state the exact cost of a restoration.
The most reliable method would be to have the condition of your motorcycle assessed, communicate the desired restoration areas, and get an estimate.
Additionally, there is a certain number of people, known as "restorers," who perform DIY restorations outside of professional shops.
However, restoring parts that require ordering specialized tools and components is difficult for amateurs.
Therefore, another option is to purchase an already restored motorcycle instead of undertaking the restoration yourself. It might be worthwhile to compare the cost of restoration with the price of a restored vehicle and choose the more affordable option.

Honda "CB400FOUR"

The "CB400FOUR," commonly known as the "Yon-Foa," debuted in 1974. It was born as the successor to its predecessor, the "CB350FOUR."
To erase the image of its predecessor, which had poor sales, it was designed with an active incorporation of European-style elements such as continental handlebars and a 4-into-1 exhaust system.
As a result, the "CB400FOUR," a Japanese motorcycle with a European style, became an innovative model that completely changed the design of Japanese motorcycles. After its debut, it captivated many riders as Honda's smallest displacement multi-cylinder, which was rare at the time.
Furthermore, by adopting Yoshimura's collected exhaust pipe as a genuine exhaust system, it revolutionized the image of multi-cylinder exhaust sounds. While Yoshimura is now standard for the Yon-Foa, this machine was the one that created that standard.

Kawasaki "500SS Mach III"

The "500SS Mach III (Three)" was launched in North America in 1969, at a time when Kawasaki was expanding its sales channels to the United States.
It featured a distinctive deeply-sculpted tank designed with America in mind, and incorporated cutting-edge technologies of the time, such as Ceriani front forks without fork boots and a featherbed frame.
This model was also built with the aim of being the fastest in the world, equipped with a newly developed air-cooled 2-stroke in-line 3-cylinder 500cc engine. As a result, it reached 60 horsepower and a top speed of 200 km/h, making it truly the fastest motorcycle in the world.
The Mach III remains highly popular as a great model that made Kawasaki famous across the ocean.

Yamaha "RZ250"

When the "RZ250" appeared in 1980, environmental issues from the late 1970s were becoming a hot topic.
Therefore, in the world of motorcycles, there was a growing recognition that 2-stroke engines were outdated. It was in such an era that Yamaha released what was praised as the "ultimate sport" – the "RZ250."
It was equipped with a high-output 35-horsepower liquid-cooled engine and was the first on-road model to adopt the revolutionary Aircross suspension.
It was also a meticulously designed model, featuring cast wheels inspired by the flaming halo of Fudo Myoo.
As a result, it became a massive hit model, far exceeding Yamaha's expectations, and continues to maintain high popularity among discontinued models in its class even today.
The "RZ250," developed against the trend of the times, is also said to have ignited the subsequent motorcycle boom.
