that was a good read on that. first time i saw that article about the nova. it was nice to see they had a pic of the fxrt on there also. which mine is an 83 with the inclosed chain drive. one day i hope to get it restored as soon as i find the other parts to do it with. |

very interesting. makes you wonder what is behind the curtain right now at "the motor company." they've done very well for themselves, seems like everyone is willing to pay $20k for a 70hp,700 pound motorcycle. |

That was interesting. I wonder what Buell could do with a watercooled V4 pushing well over 100 hp and reving to 10K. I'm sure that configuration could be made to have well over the 135 hp they talked about in the article with the current technology. The short stroke would also allow for a lower center of gravity because the cylinders would be so much shorter. Very interesting. |

The 9 is still the same engine as the 12, so that is a little different. Look at how short the cylinders are in the pictures in the article. My assumption, and maybe an incorrect assumption, is that the short cylinders is becuase the stroke of the engine is shorter. If that isn't correct, why are the cylinders so short in the pictures or on other short stroke twins and ours are so tall? |

glitch, if a motor is designed from the "ground-up" , it can be much shorter. buell used "parts bin engineering" on our beloved "9". |

The stroke of an XB9 is shorter than an XB12 and the cylinders are the same hight. But the rod arms are longer on the 9 than the 12 so that's where it makes up the diff |

when you are using a narrow "V" (45-60 deg.) you cannot "sink" the pistons too close to the crank because the piston skirts will try to occupy the same space. on a 90 deg. V (ducati) the pistons barely "leave" the engine cases ! (the majority of the cooling fins are on the heads.)so in ducatis case short stroke = short motor. |

A couple of classics on the same site: http://www.bikerenews.com/AntiqueBikes/1979Kawaski Z1300sixcylinder.html In 1980 I owned a CBX-6 but I was very tempted by the Z13 And I always wanted one of these: http://www.bikerenews.com/AntiqueBikes/1981HondaCX 500Turbo.html |
