The Japanese firm will present the new generation of EICMA motorcycle driven by a 700 cc twin-facing, also equipped with 6-speed dual-clutch. Ready also the new 4-stroke engine 125. Consumption records for all


Honda is preparing to present a family of three models, distinguished by a single “platform” (ugly term, usually referring to the world of cars, but there it is …), the first of which we know already: it is the motion Integra-scooters at EICMA 2010. And now that Honda returns as final, and most tourist configuration. The other two, for now, no one knows anything yet. The House then Tokyo has thought to create a series of vehicles and mid-size high-quality , manufactured according to different concepts to meet the needs of rapid movement of various types of users around the world, while still providing ease of driving, operating cost and a high respect for the environment.



Media characterized by a low center of gravity, therefore, easy to approach, with a high-torque engines, especially in the low to mid range: an engine, as is well known, parallel twin-cylinder liquid-cooled 700 cc (bore and stroke 73×80 mm ) logically powered PGM-FI electronic fuel injection combined with the second generation of sophisticated dual-clutch transmission with electronic control that began last year with the mighty VFR1200 DCT – first bike in the world to use such a solution – with the possibility of using a six-speed manual transmission. The DCT transmission ‘second generation’ , made ​​with the technology already appricate ATV vehicles, is smaller and lighter, and has a hydraulic circuit shortened by 40%, and a built-in linear solenoid the right crankcase cover, replacing the outer year. The software also has a new feature here, which further facilitates the guide, in practice, now the system is able to recognize – no matter the choice made ​​by the pilot – if you are driving in the city rather than a step mountains, and adjusting its response times, and optimizing fuel consumption. The new twin-cylinder Honda, SOHC 4-valve per cylinder, has thermal units tilted forward 62 °, 270 ° phased and has balancer to reduce vibration, which also drives the oil pump. Aspiration avviente through a single tube that serves both cylinders, split internally to allow the flow of power to serve the combustion chambers at different times, with the help of special dual intake camshaft profile. This sophisticated engine is mileage credited with a good 40% higher (according to the calculations of the designers) twins compared to maxi-scooters that currently exist: it is declared more than 27 km / liter (WMTC calculation mode, as usual, Honda), Very low unloading at the level of carbon monoxide (CO) and hydrocarbon (HC) and nitrogen monoxide (NO), thanks to the work of the three way catalytic converter, exhaust manifold in the one placed immediately at the exit of the ducts in it converged in order to activate immediately. Very low power consumption, therefore, and also reduced the tank – but with considerable autonomy – to the benefit of the entire project, in terms of compactness and general ability to “stow”, which is crucial for users of such transportation. The House Japan is also preparing to market an engine of 125 cc, 4 stroke, 4 valves per cylinder and electronic fuel injection. And ‘dedicated to the global market and is characterized by the low cost industry, which makes it suitable for emerging markets (India, Brazil) and reduced operating costs, from fuel consumption.
