Went and weighed the Bighorn this AM.
Weighed in at 110kg dry [44% front, 56% rear]. In USA terms, that's 242 lbs. Taking a little scale innacuracy plus some fluids, you're most probably looking at 250lbs. That's not as light as the DB bike, but certainly not disgraceful.
BTW, I weighed in my '79 KLX 250 afterwards and it came in on exactly the same weight: 110kg [45% front, 55% rear]
I also weighed 3 frames and will post the results in the topic above.
