When I looked up the dry weight of the 2003 FJR1300, the information stated that the bike had a dry weight of 522 pounds. NADA has it as 521lbs dry. The first is the number I originally used.
Information I found stated that the early FZR1000's where in the 470lbs dry weight class. 522 minus 40 for the exhaust and bags would put the dry weight of the bike within approximately 10 pounds of the earlier FZR1000.
That is the info I based my comments on. If my statement is incorrect, that is the reason why and I apologize. I simply went by what I found when looking up the statistics up.
After looking further into it, a few other sites have it as 537 lbs dry weight...
Conservatively, I put the weight of the side bags at a minimum of 10lbs each. I don't know the exact weight of them, but to me personally they feel north of 10lbs. I don't have a scale. A Givi 21 liter side bag is 9.9 pounds and a 34 liter bag is just over 17 pounds. So I guessed that the FJR bags would probably fall some where in that range.
It's also not uncommon to get a weight savings going from 4 into 2, to 4 into 1 of 23 -25 pounds. So I don't think 20 pounds is a stretch.
Take off the center stand, and there would be a few more pounds dropped.
Again, as I stated, I simply used the dry weight figures I found online. If wrong and the bike is heavier, that of course would change the claim. But it would not change the fact that the FJR has a lot to work with when it comes to working it up.
To me personally, and to most people I have ever known over the years both in the industry and that ride, the FJR's gearing, it's 1300cc engine, as well as the bike's chassis, give you a lot of bike to work with if you want to blow out the motor and make a muscle-bike beast. There have been a lot of heavier, less powerful, far worse handling bikes that many people I have known over the years have worked into beastly works of art.
