The History of Bridgestone Motorcycles

Bridgestone GTR 350

From Tires to the Motorcycle World

Bridgestone Corporation, best known as the world's largest tire manufacturer, once ventured into the motorcycle industry. Founded in 1931 in Japan, Bridgestone initially focused on tire and rubber product manufacturing. However, from the 1950s to the 1970s, Bridgestone briefly but memorably made its mark in the motorcycle industry, producing high-quality vehicles that are still remembered today.

Bridgestone’s Initial Steps into the Motorcycle Industry

After World War II, Japan saw a surge in the automotive industry, and the success of brands like Honda, Yamaha, and Suzuki in the motorcycle market inspired other companies to follow suit. Bridgestone began its journey in the mid-1950s by manufacturing motorcycle parts for these companies. By the early 1960s, Bridgestone decided to launch its own motorcycles, focusing on the smaller and mid-size segments of the market.

Launching the First Motorcycle

In 1963, Bridgestone introduced its first motorcycle, the Bridgestone BS 7. This compact 50 cc two-stroke machine was lightweight and well-suited for urban commuting. Bridgestone went beyond just size by incorporating advanced technology, including an automatic transmission system and electric ignition, rare features for small motorcycles at the time.

The success of the BS 7 paved the way for other innovative and powerful models. The Bridgestone BS 50 became a popular model, offering fuel efficiency and durability, making it one of the top choices for daily transportation in Japan.

Expanding Models and Technological Innovations

With increasing demand, Bridgestone released several iconic models throughout the 1960s. One standout model was the Bridgestone 90 Sport. Equipped with a 90 cc two-stroke engine, it delivered impressive power for its size, making it a strong performer on the road. Bridgestone also included a four-speed transmission, which enhanced performance and speed.

The Bridgestone 175 DT became a groundbreaking model in its class. Launched in 1966, it featured a 175 cc two-stroke engine with high power output. With an advanced air cooling system, a five-speed transmission, and a lightweight frame, the 175 DT was popular among riders seeking a combination of speed and handling ease.

The 175 DT became an icon due to its ability to compete with models from other major manufacturers. Bridgestone earned a reputation for delivering high-quality products that could seriously compete with larger players in the market.

Racing Success and Influence in the Export Market

In the 1960s, Bridgestone also began participating in motorcycle racing to showcase the performance and quality of its products. With advanced and innovative technology, Bridgestone motorcycles achieved impressive results in various local races in Japan and even won championships on multiple occasions.

This success positively impacted Bridgestone’s sales, especially in the export market. Bridgestone expanded to the United States and Europe, offering motorcycles with advanced technology, affordable prices, and easy maintenance. In the U.S., Bridgestone even became a top choice among young riders looking for an alternative to dominant domestic brands.

Models like the Bridgestone 100 TMX and Bridgestone 350 GTR were particularly popular in export markets. The 100 TMX was an off-road model with a 100 cc engine ideal for various terrains, while the 350 GTR attracted sport bike enthusiasts with its aggressive design and powerful 350 cc engine.

Challenges and Market Competition

Despite Bridgestone’s international popularity, challenges arose within Japan. Honda, Yamaha, and Suzuki were aggressively advancing in technology and marketing while offering models at more affordable prices. As a tire-focused company, Bridgestone struggled to keep innovating in the motorcycle sector. Nevertheless, it continued production, introducing several variants aimed at different market segments.

Another issue Bridgestone faced was stricter emission regulations in some export countries, particularly the United States. Bridgestone’s two-stroke engines struggled to meet these environmental standards. Limited resources and a primary focus on its tire business hindered Bridgestone’s ability to quickly develop four-stroke engines or eco-friendly emission systems.

The Decision to End Motorcycle Production

By the early 1970s, the motorcycle market had grown increasingly competitive, and rising production costs led to losses for Bridgestone’s motorcycle division. After weighing several factors, Bridgestone decided to cease motorcycle production in 1971. This decision was deemed logical, considering Bridgestone’s core tire business was expanding and providing far greater returns.

The move was also reinforced by an agreement with other Japanese motorcycle manufacturers. As part of this arrangement, Bridgestone refocused on tire manufacturing, strengthening business relationships with Honda, Yamaha, and Suzuki, who became major buyers of Bridgestone tires.

Bridgestone’s Legacy and Influence in the Motorcycle World

Although Bridgestone stopped manufacturing motorcycles, its products remain cherished by collectors and vintage motorcycle enthusiasts. Models like the 90 Sport and 175 DT are sought after by collectors for their unique designs and advanced technology of the time.

Today, Bridgestone fan communities remain active, especially in Japan and the United States. Enthusiasts frequently organize meetups and exhibitions to celebrate Bridgestone’s legacy in the motorcycle world. These motorcycles are considered a testament to Bridgestone’s innovation and competitive spirit, reflecting the company’s values as a global corporation.

Conclusion

The history of Bridgestone motorcycles is an intriguing chapter in the company’s journey. Though short-lived, Bridgestone’s contributions to the motorcycle world demonstrated its ability to produce high-quality products beyond its primary focus.

The decision to exit the motorcycle market may have been difficult, but it allowed Bridgestone to focus on its core business, ultimately leading to global recognition.

The legacy of Bridgestone motorcycles endures and is still valued by enthusiasts. The innovations and quality offered by Bridgestone remain a testament that, although it stepped away from the motorcycle arena, the company once stood as a bold and innovative player.
