motor hornet

Nas reuniões anteriores ficou como hipótese a utilização do motor da honda hornet 600 F7. Como tal deixo aqui umas informações desse motor, sendo que futuramente discutiremos futuras opções.

Textozinho em inglês para irmos treinando

The small 599cc in-line four engine wakes to life in a quite un-intimidating manner. We shall not forget that it comes directly from the CBR600RR supersports, but with different cams and intake valves for a broader range of power. The new engine is a full 5 kilos lighter than the one it replaces.

The nature of these engines can not be changed easily to suit a naked all-round sportsbike such as the Hornet, but Honda has done their best and the engine is useful enough also in lower rpms. There’s very little happening when accelerating with full throttle opening in sixth gear from low rpm. However, what could I expect? It’s a small engine with four tiny cylinders in a row and not a big twin. So revs are still needed, but perhaps less so than on the 06 model.

The fuel injection is a gem in this class and only once going off the throttle at around 3.000 rpms I noticed a very small hick-up. It was so small that I shouldn’t really have mentioned it. That’s how small and the fuelling is a mile better than Suzuki’s otherwise brilliant GSR600. The 07 Hornet features class leading horsepower too beating the GSR, Yamaha FZ6 and only four hp short of the new Kawasaki Z750 (106ps) with the claimed 102 HP engine.

But that’s all 10K+ territory riding and there is a big sports element in the new Hornet. The six-speed gearbox is as smooth as could be expected and the ratios suits both sports riding and short shifting.

Espero que não tenhas tirado isto do wikipedia lol.

Estes dois motores são bastante semelhantes. Visto que um vem do outro. Já me disseram que entre os dois a única coisa que difere é a parte eléctrica.
Mas como o teu texto refere, as cams e as valvulas também são diferentes.
Gostava de ver esta duvida esclarecida. Podemos sempre ir à motoboxe e falar com os experts.

Ontem tive a tirar medidas de um motor de uma Dyane 2 cvls. Os resultados foram engraçados. Depois faço um post sobre o motor.

Agora gostava também de ver os dados tecnicos sobre os mono cilindros e bi-cilindricos.
O binário também é algo muito importante.
