BSA (Birmingham Small Arms) Sidecar Tour

Tracing the Historical Footprints of BSA Pematangsiantar: The Legend of British Motorcycles in Simalungun Land

Pematangsiantar, the second-largest city in North Sumatra, holds a unique colonial heritage found nowhere else in the world on the same scale. This heritage is not a static building or a stone monument, but a moving historical site known as the BSA (Birmingham Small Arms) Sidecar Tour. The presence of these classic British motorcycles has become a cultural identity deeply intertwined with the pulse of Siantar's community for over seven decades.

Historical Origins and the Arrival of BSA in Siantar

The history of BSA in Pematangsiantar began during the post-World War II transition period and the early days of Indonesian independence, around the 1940s to 1950s. Birmingham Small Arms (BSA) itself was a British manufacturer of weapons, vehicles, and military equipment headquartered in Small Heath, Birmingham. During the Dutch occupation and later the British (as part of the Allied forces), these motorcycles were brought into the North Sumatra region for military mobility needs and the operations of large plantations around Simalungun.

The most dominant models in Pematangsiantar were the BSA M20 and M21 types with 500cc and 600cc engines. These motorcycles were initially designed for wartime (World War II) due to the robustness of their engines in difficult terrain. When the colonial forces left Indonesia, hundreds of BSA units were abandoned and subsequently transferred to the local population. Uniquely, in Pematangsiantar, these motorcycles were not merely private collections but were modified into a form of public transportation, a motorcycle rickshaw (betor), with the addition of a sidecar.

Construction Details and Mechanical Architecture of the Sidecar

Technically, the BSA motorcycles in Siantar are mechanical masterpieces from the pre- and post-war era. Their engines use a very simple side-valve system but possess immense torque, enabling them to pull heavy loads on Siantar's hilly roads. The frame construction is made of very sturdy cast steel, capable of supporting the locally made sidecar modifications.

The sidecar modifications in Pematangsiantar have distinctive architectural characteristics. Unlike modern sidecars made of fiber, the BSA Siantar sidecars are built using iron frames and sheet metal or wooden bodies with an aerodynamic yet classic design. The passenger seat inside the sidecar is usually upholstered in synthetic leather with a capacity for two adults. The integration of British motorcycles and locally made sidecars creates the aesthetic of a "Moving Historical Site" that blends European technology with Indonesian local creativity.

Historical Significance and Related Events

BSA Pematangsiantar played a crucial role in Indonesia's transportation history. From the 1950s to the 1980s, BSA was the economic backbone of the city. These motorcycles were used to transport agricultural produce from the outskirts to the central markets in Siantar. This phenomenon made Pematangsiantar the only place in the world where British military motorcycles were used en masse as public transport for such a long duration.

One of the historical events that solidified BSA's position was the formation of the BOM'S (Birmingham On Motorcycles) community, which sheltered BSA owners and riders. This community successfully lobbied the local government to allow BSA to continue operating as public transport, even though, by modern transportation regulations, these old engines were considered inefficient. Their existence became proof of resistance against the tide of modernization that often erases historical traces.

Important Figures and Periods

The names of legendary mechanics in the Asahan Road and Merdeka Road areas are key figures in the preservation of this historical site. Without their expertise in "cannibalizing" spare parts or creating replacement components manually (hand-made), BSA would surely have become extinct since the 70s. Furthermore, former Mayors of Pematangsiantar and local community leaders often used BSA in cultural parades, making it a symbol of regional prestige and pride.

The golden period of BSA in Siantar occurred before the introduction of more fuel-efficient Japanese-manufactured motorcycles. However, it was precisely during the difficult times of the 1990s that BSA transformed from a mere means of transportation into a tourism icon. Collectors from Europe and Australia began to visit Siantar to see the "living graveyard" of British automotive history still roaring on the roads.

Preservation Status and Restoration Efforts

Currently, BSA Pematangsiantar is categorized as a non-building cultural heritage object. The main challenge for preservation is the scarcity of original spare parts from England. Restoration efforts by owners usually involve engine modifications using truck pistons or old car components to keep the motorcycles running.

The Pematangsiantar City Government has inaugurated the Tugu Becak Siantar (Siantar Rickshaw Monument) as a form of tribute to BSA's history. Additionally, the "BSA Sidecar Tour" program is now a flagship tourist package. Tourists are invited to tour the city, visiting other historical sites such as Vihara Avalokitesvara or the Simalungun Museum, by riding a BSA sidecar. These efforts aim to ensure that the presence of these motorcycles provides higher economic value to their owners, preventing them from selling the motorcycles to foreign collectors.

Cultural Meaning and Local Identity

For the people of Siantar, the distinctive rumble of the BSA engine (often called the "helicopter" sound) is daily music that evokes nostalgia. BSA is no longer just a vehicle but a family member passed down through generations. Culturally, BSA symbolizes the resilience and endurance of the Pematangsiantar community in facing the changes of time.

The existence of the BSA Sidecar Tour also has a social dimension as a unifier. BSA rickshaw drivers come from various ethnicities and religions, who collectively preserve this heritage. Amidst the onslaught of online transportation and urban modernization, BSA remains as a reminder that Pematangsiantar was once an important point on the colonial logistics distribution map and has now transformed into the most unique open-air automotive museum in Southeast Asia.

A unique fact rarely known is that several BSA units in Siantar are very rare military series, which in their home country are only kept in museums, yet in Pematangsiantar, these engines are still working hard transporting passengers and goods every day. This is what makes the BSA Sidecar Tour a historical site not just to be seen, but to feel its vibrations and hear its sound.
