Very interesting. There was a guy in Sweden doing this a while back, name of Jan something I think, but you had to send him your computer and he'd mod it and send it back. Obviously you couldn't use a bonneville computer in our bikes coz the bonne's coils both fire at once, whereas ours are 90 degrees apart. No reason they couldn't do the same mod on ours tho. If you're on an America you can already get a 500rpm higher redline by getting your hands on a speedmaster computer, so theoretically you could get a 1500rpm higher redline by putting a mod'd speedy computer in an america. Would it be safe in the long term? Probably not, or Triumph would have set it higher themselves.
The website mentioned in the auction looks like it's still being built. If you click on one of the "bike type" pics you just get the pic instead of a menu. Worth keeping an eye on though.
