A New Era

The New Africa Twin Emerges at Last

The Africa Twin, a legendary machine of which Honda has long been extremely proud, and a pioneer of the Adventure Tourer category of large-displacement dual sport motorcycles, is making its return. Impassioned requests from enthusiastic fans around the world have finally borne fruit nearly 15 years after production of its predecessor model came to an end.

The passion with which a small group of young engineers kept alive the dream of creating a new big off-roader, an Adventure Tourer, gradually expanded, resulting in the rebirth of the new Africa Twin.

The new African Twin they eagerly sought to create would maintain its predecessor's fundamental concepts while being infused with the best of over 25 years of accumulated state-of-the-art technology. A full-cowl touring model powered by a large-displacement engine that is also capable of freely venturing well off the well-travelled road — this concept has now been revived and given new form. A well-rounded machine that expert development engineers finished with the passions of young engineers in mind. Completed with a wide range of riders in mind, from relative novices to adventure experts, and from touring aficionados to off-road fans — This is the new Africa Twin.

This new Adventure Tourer is powered by a newly developed liquid-cooled SOHC Unicam 4-valve parallel-twin engine. Although the original Africa Twin was known for its V-twin engine, one reason that the new Twin does not employ the same design configuration is that an engine type that best matched the machine's new compact proportions needed to be selected. The engine's forward-canted parallel-twin layout helps realize a shorter longitudinal length than possible with V configurations, further making it possible to shorten the overall length of the chassis and its wheelbase. Also, relative to the V engine, this compact twin further offers the merits of centralized mass for more responsive handling, and a slimmer shape in the seat area.

The 998cc engine's output of 70kW was determined to be more than sufficient for both long touring and off-road adventures. This also allowed the chassis to be designed for lighter weight and more compact proportions, as well as offering easy control. Further, its 270-degree offset crankshaft provides excellent traction from low in its rev range, and strong, responsive acceleration, delivering up a pulsating engine feel that only an irregular combustion interval can provide.

Additionally, the Honda Selectable Torque Control System (HSTC) is offered as standard equipment. This electronic control system controls the amount of engine torque reaching the rear wheel in order to minimize slippage and wheel spin, and maintain an appropriate posture while riding. This control system can also be manually disabled during sport riding, and can be said to be symbolic of the importance attached to the Africa Twin's off-road riding capabilities. Moreover, the Twin's switchable Antilock Brake System (ABS) makes it possible to disable only the rear tire's ABS function, providing an extra degree of freedom and flexibility during off-road rides. In other words, the new Africa Twin is a riding machine that attaches the utmost importance to total mobility during off-road travels.

Another notable feature is a version being released equipped with Honda's unique Dual Clutch Transmission (DCT). Till now, DCT had been designed to provide greater comfort and ease during long rides. However, besides its obvious benefits during high-speed touring, it was specially adapted to the Africa Twin with off-road use in mind. Because of this, a 'G Switch' was added, which enables the capacity of the clutch to more closely conform with engine torque output whenever momentary increases in traction are needed when travelling off-road. This can also be disabled whenever a more gentle application of the clutch at low revs is preferred, enabling the rider to gain a more visceral feeling of the engine's power, depending on riding conditions. Additionally, a hill climb/descent detection function has also been added, allowing appropriate speed adjustments when travelling up and down steep hills.

Although the Africa Twin's vehicle weight is virtually the same as that of its famed predecessor, in the quest for more effectively centralized mass, weight distribution was calculated to provide more responsive controllability, better enabling it to confidently venture off road, even though it is at its heart it is a large-displacement touring model.

The Africa Twin's styling was designed with an emphasis on providing a slim and lightweight feel while offering a sense of substantial volume. Its bodywork features an integrated form free of bulging protrusions that helps minimize damage in the event of a fall while riding over rough roads.

A young team of development engineers contemplated what an Adventure Tourer of the future should be, and succeeded in making the new Africa Twin a motorcycle that tempts riders to explore new roads and lands off the beaten path, whether riding tandem or fully loaded with touring luggage.

Adventure does not necessarily mean only charging out across undeveloped lands or deserts. Venturing off onto an unexplored side road for the first time can also be an adventure - this machine enables its riders to actually experience such feelings. Welcome to the new Africa Twin, the ideal Adventure Tourer for a new age.
