"Fact of the matter is, your XB is a virtual showcase of technology. As with women, the best parts are not always visible to the eye."
See, that's why I like german engineering (Hate the cars though... you ever step the back out in a 911 and then have the misfortune of deciding to let off the gas? Me either, but it's bad... Also, brake in a STRAIGHT FREAKIN LINE in a 911), you always know those Germans were THINKING when they designed something. Just like Toyota. |

How does the Breakaway steering Head work and what is it's purpose?
Thanks |

In the event of a severe front end collision, the neck of the frame is designed to break away without rupturing the fuel section. |

I wonder if coming down very hard from a wheelie could cause the neck to possibly break away? |

The Breakaway Steering would not be a great thing to happen in a wheelie. I was wondereing also what models have the Breakaway Steering?
Anyone know? I mean is it on the Blast too? I have considered buying a Blast and really like the way it handled. I also like the design of the XB9 because it fits me.
I would hope that it could not inadvertantly breakaway. I am sure that they probably passed all tests on it otherwise they would not have been able to put it on a cycle. I have did notice the Blast took the bumps pretty well. Went over some railroad tracks etc. Suspension was a
little squishy not quite as tight as I would like but that is ok. I can see the value of the Breakaway Steering in the case of the fuel being in the frame. I think some folks get on cycles these days and have little experience and buy too big a machine for themselves.
I was just talking to a kid no older than about 18-20 who had gone home on a 1,000cc machine. He was bragging about how he had ridden it around in the lot and then rode it home! That is a frighteing thought!
Some people seem to believe that a cycle cannot get away from them. Oh well, thanks for the info on the Breakaway Steering. |

Someone who knows answered this question way back, it is in the archives in the "deer accident" discussion.
The breakway steering head assembly won't break away unless the impact is serious enough that a traditional from wheel would be effectively rendered unusable anyway, either from bending up the wheel, or by forcing the wheel and triple tree assembly back into the engine.
No worries. It's just made to give in places it won't leak before it gives in places that do leak. It won't give unless it's too late for anything else anyway.

ABSOLUTELY IMPOSSIBLE....and PROVEN to be impossible |

Think of it like a crumple zone in the front entd of a car, or even one of the newer pyrotechnic steering columns.
The components/frame are designed to break away under certain impact loads to bleed away stress. In a car, most of this is aimed at keeping the steering column (those pyrotechnic ones are pretty cool - basically a shaped charge blows the steering column in half) and engine from going through the driver's seat.
I would imagine on a bike such as the XB it's to lessen the amount of kinetic energy transferred to the rider as he's pitched off the bike, since there's nothing attaching them to each other.
Remember Ben's deer incident a few months ago? The front end of his Firebolt separated just like it was supposed to. Now, we'll never know for sure, but I wonder what would have happened had the steering head NOT been designed that way?

Buell was testing their frame/fork assemblies on a machine that was simulating stoppies and wheelies and extreme braking, basically way more and much harsher than 99% of the owners will ever approach.
I've just got a thing about aluminum framework that I bring over from the bicycle world, so my underlaying opinions are somewhat jaded. Beyond that though, seeing the testing in action, you should have no fears about premature failures. |

>>>testing their frame/fork assemblies on a machine
I just sent the "machine" an e-mail and told him he'd been promoted to "machine" status. This has alleviated his concern, spawned by the Federal Acoustic Emissions test folks, that he'd end up being "just a number".
He said "thanks" (with a VERY mechanical tone in his voice)
Actually...there were real and simutlated and a host of other test conducted.
NOTE: No Elves were harmed in the design of the Buell XB platform. |

It sure looked like a machine laying on it's side next to a aisleway flexing the fork/frame assembly up to what looked like several inches back and forth and up and down. I guess there might have been someone strapped in under the deck in there someplace, and if so I sure hope they gave him a little water from time to time as he never made so much as a squeak or peep while the dozen or so of us were standing around watching the assembly get hyperflexed.
Some things never cease to amaze me.

FYI... Mr. and Mrs. Dyna's "tankslapper" accident transpired on a big Harley cruiser bike, not a Buell. |

And I never ever stated otherwise.
Mine was totally road grime related. Diesel fuel on a curve is not good. It wasnt the actual tank slapping that casued my accident, it was the shit on the tires & the way the rear end wanted to be where the front was.
