Bultaco was a Spanish manufacturer of motorcycles that operated from 1958 to 1983 before reopening in 2014. Founded by Francisco Xavier Bultó, Bultaco gained recognition for their innovative designs and domination in off-road competitions with models like the Pursang, Sherpa T, and Astro. The company played a significant role in revolutionizing trials biking in the 1960s and achieved great success in both World Trials Championships and events like the Scottish Six Days Trial. Though production ceased for a period of time, Bultaco made a comeback in 2014 with a new series of electric motorcycles.

The History and Rebirth of Bultaco Motorcycles

Bultaco motorcycles is a brand known for its bizarre and unconventional history. Founded by Francesco Javier Bulto, a racing enthusiast, the company pioneered creating bikes directly through racing. Bultaco initially partnered with engineer Pede Pimenir to create Montesa, but conflicts arose between business interests and racing goals. As a result, Montesa's board of directors voted to end the company's racing efforts - ultimately betraying Bulto. In an act of rebellion, a production manager named Juan Shalom suggested starting a new company, and Bulto agreed. Due to manufacturing license restrictions, Bultaco had to associate with a struggling manufacturer called Monfort. The factory was set up in an old farmhouse in San Adrian de Besos, Barcelona, with employees living and working on-site. The first Bultaco prototype, a 125cc machine, was completed on October 3rd, 1958.


Bultaco soon gained recognition from dirt bike enthusiasts all over the world as its models exhibited an unparalleled balance of power and agility. Despite being famous for their off-road capabilities in America, they arrived too late to disrupt Honda's already established dominance in the market.


Bultaco motorcycles has a unique and tumultuous history, marked by conflicts with its partners and a rebellious act to start a new company. Despite their reputation for producing powerful and agile off-road bikes, Bultaco arrived too late to challenge Honda's dominance in the market.


Original Days & Closure in 1983

However, substantial sales resumed after the introduction of OEM engines incorporated into new designs. The 60's and the early half of 70’s saw the release of some iconic models - like the Sherpa T series trials machines and original short-circuit racers such as the TSS 250 road racer. Yet financial troubles hit the company leading to banks stepping in to secure their investment leading later to closure in 1983.


Despite closing over three decades ago during Spanish crises that led countless companies shutting down, at RunMotorRun we are excited about how Bultaco is making strives back into the market. While some model concepts are redesigned versions of original models, complete with original colors, Bultaco has revolutionarily blended technology with traditional design in their electric bikes in recent years.


With its unique history and impeccable engineering behind each machine produced it's hard not to have respect and admiration for what Bultaco has managed to achieve over the years.


Reopening & Transition to Electric Models

Bultaco, a motorcycle manufacturer with a rich history of producing high-performance racing bikes, seemed to have gone dark after financial difficulties that led to its closure in the late 1970s. However, in 2014, it re-emerged as Bultaco Motors and began developing electric motorcycles. Offering high-quality electric bikes that benefit from the company's experience as a motorcycle manufacturer. Bultaco entered the electric bike market in 2015 with the announcement of their first electric bike, the Bultaco Brinco, which was half motorcycle and half bicycle.

Combining the design elements of both motorcycles and bicycles allowed them to develop an innovative e-bike designed for on-road and off-road riding, establishing Bultaco's reputation for reliability across all terrains. The Spanish motorcycling giant offers six high-tech electric bicycles in its Brinco line - each uniquely designed for distinct riding experiences.


  • Bultaco, a Spanish manufacturer, produced two-stroke motorcycles from 1958 to 1983 and reopened in 2014.
  • Their motorcycle, the Sherpa T trials bike, revolutionized the sport of trials in the 1960s by rendering heavy four-strokes obsolete.
  • The company dominated the World Trials Championship in the 1970s, winning the title eight times and was also successful in the Scottish Six Days Trial.


Understanding Bultaco's Design Philosophy

Bultaco's design philosophy has always been about creating models that are innovative yet practical. This approach is evident in their new line of electric bikes. Each model boasts best-in-class specifications tailored to the rider's needs. Despite configuring their next-gen bikes with futuristic specs like complex algorithms for regenerative braking and a cutting-edge power management system, Bultaco still recognized classic design principles while constructing their machines.

Model Name Max Speed Colors Available Weight (kg) Certification
Brinco R 45 km/h Red, Green, Black 39 kg Moped certification
Brinco R-B 45 km/h White/Black/Yellow 33 kg Moped certification
Brinco S 45 km/h White/Black 39 kg Moped certification
Brinco RE 45 km/h Black/White/Orange/Yellow 42 kg Moped certification
Brinco C 30 km/h White/Black/Yellow 36 kg Moped and Bicycle Certification
Brinco Discovery 50 km/h Black/Grey 39 kg Moped certification

Bultaco has always had the aim of creating futuristic motorcycles that go hand in hand with environmental resilience while still maintaining practicality. The brand's designs focus on efficiency, power, and style to keep up with today's fast-paced world.



As an example, The Brinco R features a unique suspension system that provides enough strength for the bumpiest of trails while ensuring the ride remains smooth and comfortable. This feature is vital as off-road enthusiasts tend to exert long hours into bumpy tracks that often require excellent shock absorption capabilities.

Feature Description
Independent motor and pedals A distinguishing feature between electric bikes and two-wheelers equivalent to mopeds. This design allows for greater control over the bike' riding style.
Three Riding Modes Eco, Tour, Sport
Integrated Wi-Fi Connectivity Enables riders to access information regarding their motorcycle's battery level, speed, location, among other metrics from their mobile devices.

The signature Spanish brand has always made strides towards efficient and stylish dirt-bikes with its trademarked Bultaco bravado. Their unique designs capture both form and function, making them a fantastic option for any rider seeking reliability across diverse terrains.


Distinctive Two-Stroke Engine Design

Bultaco's reputation for manufacturing high-quality motorcycles lies in their distinctive design and engineering. Unlike most motorcycle manufacturers at the time, Bultaco opted for two-stroke engines in their bikes. Two-stroke engines have a simple design with fewer moving parts, allowing for lighter weight and greater power output while requiring less maintenance.


For example, the Sherpa T featured a 246cc single-cylinder two-stroke engine with a five-speed gearbox. This made it lightweight and agile, perfect for maneuvering on rugged terrain. The two-stroke design also provided a burst of power when the bike was revved up, making it ideal for trials competitions where riders must navigate obstacles within a specific time limit.


Bultaco's innovative two-stroke engine design can be found in all their standout models that have gained notoriety among motorcycle enthusiasts.


Standout Models and their Specifications

The historic Spanish company produced several legendary models during its lifetime, each offering different benefits to its riders. Let us explore some of these machines and look at their key specifications.


Bultaco Alpina 250

One such model is the Bultaco Alpina 250. Released in 1971, this enduro bike was notable for its elegant chrome-plated tank, which gave it a stylish look. It had a top speed of 75 mph, thanks to its powerful 5-speed transmission system paired with an air-cooled 2-stroke engine that generated a maximum power output of 25 horsepower.

Bultaco Pursang

Another iconic model is the Bultaco Pursang. This motocross bike had variations ranging from 125cc to 370cc over the years, but the most popular was probably the Pursang Mk6 that was released in 1974. It came with Marzocchi front suspension, Betor rear damping and boasted a five-speed gearbox with a chain final drive. Its four-petal reed valve design two-stroke engine was capable of producing an impressive 36 horsepower with a top speed of around 85 mph.

Bultaco Frontera

The Bultaco Frontera was another popular model, released in 1975 and known for its versatility. It could be used both on and off-road, thanks to its terrain-following suspension. The bike had a powerful 250cc engine that produced a top speed of approximately 78 mph. It came with a five-speed gearbox paired with a chain-driven final drive.

Bultaco motorcycles were renowned for their excellent performance, durability, and style. The brand's unique two-stroke engine design makes them stand out among their market peers and brought competitive advantages to riders in different disciplines. Understanding the specifications of different models helps you determine which one best fits your interests and personal preference.


The Sherpa T and its Impact on Trials

Bultaco made several successful models over the years, but none had as much impact on trials riding as the Sherpa T. It revolutionized the sport in the 1960s by rendering heavy four-strokes obsolete with its lightweight technology. Before Bultaco's innovation, trials riders almost exclusively used weighty machines that provided ample torque at low speed. As a result, sections were defined by their difficulty level based on whether riders could get through them without putting a foot down. However, the Sherpa T changed all that. Its lightness allowed it to tackle steep inclines and sharp turns with ease, making it possible for riders to complete even more advanced sections without scoring any points. The bike's success eventually saw it winning eight Trial World Championships in the 1970s.

Bultaco Sherpa T

To put into perspective how influential the Sherpa T was for trials riding, it would be like comparing Microsoft Word with a typewriter.


While the Sherpa T was king of trials during its time, Bultaco also had great success with its Pursang model on the motocross circuit.


The Pursang: A Motocross Icon

The Pursang was a popular and competitive competition model for speed-based off-road events like motocross. From 1965 to 1972, this iconic prototype evolved significantly in design and performance. Initially geared toward amateur enthusiasts who wished to combine street and off-road racing into one experience, these beasts quickly rose to become powerful competitors in numerous prestigious motocross competitions. With a strong aluminum frame that replaced older steel models' materials, Pursangs quickly became known for their excellent handling capabilities, making them consistent winners worldwide.

However, in addition to their speed and agility, Pursangs also stood out thanks to their unique style elements. One of the most notable features of the Pursang is their elongated side panels, which give their production models a sleek, race-ready appearance. These same side panels concealed fuel tanks that were purposefully placed to ensure excellent weight distribution and prevent sloshing.



In addition to handling and style, engine specification was also vital when it came to producing these top-performing machines.

The engine specifications varied from model to model, with early versions having 250cc motors while later editions gradually increased in size. Below is an overview of some Pursang models and their engine specifications:

Model Engine Size
MK4 125cc
MK8 250cc
MK12 360cc
MK13 370cc

The Pursang gained a reputation for being powerful, fast, well-built machines that could go toe-to-toe with any other racer on the track. It epitomized the perfect balance between speed, performance aesthetic appeal.


While Bultaco may have ceased production nearly four decades ago, these motocross and trials icons have left a legacy on the industry.


The Resilient Legacy of Bultaco Motorcycles

From their humble beginnings in 1958 to their eventual re-opening in 2014, Bultaco motorcycles have left an indelible mark on the motorcycle racing world. The company's founder, Francisco Xavier Bultó, parted ways with Montesa after personal differences between him and senior director Pere Permanyer led to his departure. Despite the rocky start, the company quickly gained recognition for its innovative technologies and engineering prowess.


A prime example of this is the Sherpa T trials bike, which rattled the trial racing world in the 1960s. With its lightweight construction and cutting-edge engine technology, it dominated the sport by rendering many heavy four-stroke bikes obsolete. As a result, Bultaco won eight World Trials Championships titles during the 1970s, stamping their legacy in motorsports history.


With models like the Pursang for motocross, the Matador for enduros, and the Astro for flat-track competitions, Bultaco managed to spread their influence across various off-road motorsports fields and attracted a legion of loyal fans worldwide.


Despite experiencing significant financial setbacks throughout its lifetime, including strikes and market pressures that led to multiple closures before finally shutting down operations in 1983; Bultaco has managed to remain relevant even decades after its inception.


In 2014, a new series of electric-powered Bultacos was announced - cementing forever their place as pioneers in motorbike innovation.


The ongoing fanbase and interest in these bikes are similar to vintage car enthusiasts – despite their age; they still hold sentimental value for so many within a community that values tradition and innovation alike.



The resilient legacy of Bultacos serves as an inspiration to anyone dealing with adversity. Their ability to bounce back repeatedly despite enormous challenges and continuing to innovate serves as an embodiment of the human spirit and resilience.
