Development of CRF1000L Africa Twin

Article of Honda R&D Technical Review Vol.28 No.2


The CRF1000L Africa Twin was developed with technologies for a new era while inheriting the tradition of the XRV750 Africa Twin, which pioneered the adventure sports category. Extensive weight reduction and mass centralization allows the size and weight of the CRF1000L Africa Twin to closely match its predecessor. An engine with parallel twin cylinders and displacement of 998 cm3 was employed. In addition, a dry sump system was applied in which the oil tank is integrated within the crankcase. These features contributed to enabling a powerful and compact power unit. The dynamic performances in off-road riding and the performances sought as an on-road touring motorcycle are fulfilled at the highest levels. Furthermore, a dual clutch transmission was applied for the first time to an off-road motorcycle, and has proven its effectiveness in off-road riding as well.
