Another bike that reveals distinct motorcycle philosophies is the six cylinder Benelli Sei in its 750 and 900cc forms.Those machines were damned with faint praise when they came out in th 1970s, mainly because they didn't melt the tarmac quite as much as expected. Power and torque outputs were no better than any equivalent displacement, run-of-the-mill, four cylinder Japanese machine. The motorcycle journalists quickly moved on to the next crop of UJMs to get a better all-expenses-paid power kick.But have a look and listen to some Benelli Sei footage on YouTube. If I had one of those machines I'd be forever starting it up on its center stand just to hear it idle. That straight six sound is so charismatic. The motor makes even sweeter music when it is opened up on the road. And just look at that fabulous church organ array of six silencers.If you see such a machine as worthless just because it lost the BHP and foot pounds race by a small margin then you are just an appliance user and not a real motorcyclist at all.
