Depends on the model, but an 899 weighs 417 in street trim with no gas. 1199S is about 8 lbs. lighter, and 1199R is another 4 lbs. lighter.
Interesting. Did you ever weigh a non-ABS base 1199? I know the wheels are ~5 pounds heavier, but the ABS is said to add 6 pounds, and the electronic Ohlins are an unknown amount heavier. I'm betting about 5 pounds lighter than an 1199S.
Motorcycle-USA.com's shootout had the 1199S ABS at 423 lbs with a full tank. Assuming gasoline weighs 6.2 lbs per gallon, a full 4.5 gallon tank should add 27.9 gallons, leaving the dry gas tank weight at 395 lbs, which seems about right if the SL is 366 pounds in the same state (29 lbs less).
Which would make my non-ABS base with Bitubo suspension, Termi slips and Rotobox RBX2 wheels about 412 lbs full of fuel, or about 18 pounds heavier than an SL (4% lighter). So I'm pleased to have gotten my bike as a leftover in 2013 for $16,400 and added about $7,000 of performance mods, soon to be about $8,000 with the Rapid Bike Race module getting installed this week. Aside from exclusivity, I feel like I got about 85%-90% of the SL for about 37% of the cost. At least that makes me feel better about not having one.
