I've come to the same conclusion. I've weighed mine with a bathroom scale (one wheel at a time, add both numbers), and the local department of transport scale, both times I came up with close to 415 lbs dry (no fuel). Which is quite similar to your numbers Seb. Which does represent a 70lb weight savings over stock however!
Lighter wheels, different swingarm… after that it's basically shaving grams from other parts. Although custom headers would probably help me a little…
Bike still looks amazing Seb!!
So if I subtract 34lb of fuel, I come out with a lighter bike than yours :tongue2:
I have to say, the Two Brothers header is very light. I could switch to a carbon can and save bit, drop 15-20lbs switching to a conventional swingarm and wheel... but I like my can and swingarm. It is what it is!
