just looking at this on the ti-force site;
http://www.tiforce.com/2003/models_page/other/buell.html
...wondered how much is a stock v micron v full ti system? obviously full ti is lightest but just wondered how the micron compares in full steel (exercise in sprung/unsprung weight and keeping it centralised)

Weight is always a consideration, but cracking, breaking and falling apart is another that should be added to the equation when choosing for the very demanding situation which is the Buell.

I think (correct me if I'm wrong Steve) the Micron weighs about the same as stock.
Nothing wrong with that, I've seen what happens to a light weight header (Force Street Fighter Exhaust System) and it didn't last very long at all. I believe Misato had a go 'round with the Force as well. Extra light weight is a good thing, but it's relative.

I wieghed the entire Micron system before I installed it on my bike. If I remember correctly it was about 3 lbs lighter than the stock system.

We had many long discussions and some tough choices to make when deciding which material to make the Buell system out of. In the end it was decided that to "err" on the side of strength & longevity was more critical then the couple of pounds we could have saved with more exotic materials. We have 1.5 lb complete race cans we sell every day, but whether or not they would hold up on a Buell for any length of time we don't know.

As we become more familiar with the Buell's we will probably offer some other options, maybe something of a "pure" raceline that would sacrifice some long term for lighter weight could become available.

But for now, we think riders and owners of our product will be happy with knowing the product is bullet proof for many years to come, which is a ton more fun then sitting on the side of the road with a broken exhaust or being on a first name basis with everyone in our warranty department...

most bike manufacturers harp on about how lighter is better from unsprung weight perspective but because buell is ahead of the game and the bikes seem built on this premise, I am curious to see if the weight of the stock system is integral to the design of the xb12r and its excellent handling characteristics or whether sticking a much lighter but identical system in its place would make it wallow like a fat man eating a burger whilst floating in the Dead Sea.

On a windy day.

I'm listing this from memory so don't hold me to it exactly.

Stock 12 - 19lbs. (-3lbs. for 9)
Drummer 12 - 13lbs. (-2lbs. for 9)
Drummer SS - 11lbs.
Drummer CF - 6.5 lbs.

The weight of the exhaust is sprung mass.

m1's right - exhaust is sprung so i guess changing the weight around won't have too much of an effect on handling above the benfits of being approx 5 - 7 kg lighter?
