hey guys, i'm new here. I just had a question about the Trilogy of Design. I thought unsprung weight was one thing that Mr. Buell wanted to eliminate, but wouldn't the oil in the swingarm add to that? Is the rear wheel weight not as important? oh, and by the way.. great site! |

Welcome sspazz! Yeah, while it utilized one area of the trilogy (mass centralization), it negated another (lower unsprung weight)... I'm sure Erik and his team picked best. Welcome to the site. |

Sspazz: I've read it explained like this: The oil is located at the front of the swingarm which places most of its mass right above the pivot, so that that weight is effectively sprung weight. The rear of the swing arm, which is basically unsprung weight, is made as light as possible. |

Exactly as Whodom said. The farther away from the pivot point you put the weight the slower the pendulum swings. And more effort is required to swing it. Welcome aboard, Bro. Mark |

The other issue is rotational inertia... Take a glass full of water, place it on a table and rotate it. For the most part (unless you keep spinning it) the water will stay in pretty much one position. This, coupled with the fact that the "lever arm" is very small means that the oil in the swingarm adds VERY little to either unsprung weight or rotational inertia in the swing arm.
