Four months after presenting the prototypes at the Osaka Motorcycle Show, Honda made official the launch of the new CB400 Super Four E-Clutch and CBR400 Four E-Clutch in Japan. The models rescue one of the Japanese manufacturer’s most traditional lineages, now combining the classic in-line four-cylinder engine with modern technologies, such as electronic throttle and the E-Clutch automated clutch system.

The CB400 Super Four will be the first to arrive at Japanese dealerships, with sales starting on August 21. The sporty CBR400 Four debuts on September 18. Suggested prices are 998,800 yen (about R$ 31 thousand) for the naked and approximately 1,18 million yen (about R$ 37 thousand) for the faired version.

Four-cylinder engine is back

The main highlight of the new generation is the return of the in-line four-cylinder architecture, a configuration that has marked the history of the Four line since the 1970s and has become a reference among Honda’s medium motorcycles.

The new engine has 399 cm³, liquid cooling, dual valve timing (DOHC) and four valves per cylinder. The set delivers 58 hp at 11.500 rpm and 3,9 kgfm of torque at 9.750 rpm, working with electronic throttle (throttle-by-wire).

Honda also sought historical references in the project. The exhaust follows the traditional 4-2-1 design, with apparent curves inspired by the classic CB400 Four from 1974, while the look of the CB400 Super Four refers directly to the model launched in 1992.

E-Clutch makes riding easy

Another differential of the new family is the Honda E-Clutch, a technology that allows you to start, stop and change gears without manually activating the clutch. Despite this, the lever is still available for those who prefer to drive the motorcycle in a conventional way.

The system already equips models such as the CB650R, marketed in Brazil, and seeks to make riding more comfortable, especially in urban use, without giving up the experience of a manual transmission.

TFT panel and connectivity

The two motorcycles have also evolved in embedded technology. They now have a five-inch color TFT panel, replacing the old analog instruments.

Another feature is Honda RoadSync, a system that allows you to connect the smartphone to the bike to access turn-by-turn navigation, control music and view call notifications directly through the handlebar controls – technology that has not yet been approved by the Japanese on similar motorcycles here in Brazil

Are you coming to Brazil?

So far, Honda has confirmed the new CB400 Super Four and CBR400 Four only for the Japanese market. The manufacturer has not yet announced plans to sell it in other countries, including Brazil.

Still, the interest aroused by the models in markets such as Europe and the United States raises expectations of a future global expansion, although there is no official confirmation in this regard.
