The H2 brakes are also radial not axial which allows for better and more precise control.There are lighter bikes with dual front disks.. The Kawasaki H2 is 476 Lbs and it has duals. (Of course the fact that it can go 186 MPH might make the dual disks something to appreciate).
On the 900, I think anti-skid would be a better option than dual disks..
WTF? Is English your first language?My 900 has Harley Forks and Duel Disks, there a picture on the Pic forum above page 190, it certainly make a difference to brake repeatability, I can brake hard without any fade, ridding in a country with no speed limits I don't do 65Mph cruising. I'm not sure it make a huge difference to stopping distance if your brakes are in good condition, my experience it that the limit on stopping distance I front end grip.
As some one who races alight weight (lotus7) car I'm also concerned that the un-sprung weight is increased, and this effects handling, I don't push the 900 enough to get to the handling limit, but from the car I do know its an issue to think about.
Its not cheap to do, mine was done by the first Owner.
I can't speak for Berw, but there are quite a few people on this forum whose first language isn't English. And a whole bunch more who's first language is Texting. That said, I'd love to see those dueling discs. Sounds like a good time.WTF? Is English your first language?
