Shervin, you caught me, LOL!!! My bike is a 49-state model. Yes I pulled the rear fender off! AND.... I have a shorai lithium battery. CHEATER!! HA!!!
To measure the weight, I use two cheap walmart bathroom scales that go up to 300lbs each. I place one wheel on each scale, and bam, I have instant weight bias info. I use them to set up dirt bikes mostly.
You know what is so interesting??!! The fact that the other day i was about to complete my last post by mentioning my estimate weight number opinion more specific but my lap top finished its battery (it only last less than 1 hour and 30 minutes now; It used to be 4 hours with no problem). Today, i just wanted to update the last post but since you already passed me on posting :), i will mention it right here right now! I was going to guess that in my opinion, your bike all stock with just Muzzy difference that you mention should weights 429.25lbs = 195.11kg (-/+ 3lbs) with rear license plate assembly and 428.25lbs = 194.66kg (-/+3lbs) without rear license plate assembly (oil must be 10-40 and tires suppose to be Dunlop 190/50) and 4.5 gallon of gas but my lap top battery went out.
I was wrong about the European version part, your bike is the US and Canada version and other than supporting your statment on that regard, i also verify that. If i could get a better picture of your bike, i wouldn't guess it wrong in the first place unless it was modified to European look.
If your new battery weights 2lbs, i estimate that your bike today -with Muzzy and without lisence plate and with Dunlop tires and 10-40 oil and 4.5 gallon gasoline-should weight 427.25lbs=194.20kg (-/+ 3lbs=1.36kg); You mentioned 425Lbs=193.18kg and I believe that is actual accurate weight of your bike.
Thank your for your post, information, and your honesty!
Shervin, did/do you use this truth weight for anything or was it just the thirst for truth that drove/drives you. 3-10lbs is pretty trivial in the real world, actual use of a motorcycle.
It was some for the thirst for the truth but mainly to find my start line and measure my changes on the bike.
In addition, also to understand with considering mechaical systems and their duties, what material the manufacturer used or method provided to meet safety and quality in their parts and what method they used to save or i should say shave weight from older known materials AND to find my start line and measure my changes on the bike.
3-10lbs is A LOT in real world for motorcycles in this class. You might not feel the weight because it is the state of art of engineering of several engineers, workers, designers, technicians, testers, riders, others, and several attempts to keep the total weight and most importantly central weight point as low as possible. The reason that newer bikes such as ZX-10R generation 3 and after feels lighter for the rider is becasue the central weight is lower and that is very hard to maintain for manufactorer and it is really the race of might and inteligent to see differernt methods that different manufactorers and manufactories use to accomplish that goal.
In my opinion, Central Weight Point is more important than total weight; Not only in mobile objects but also in stationary objects as well.
In a safe area do this test:
Place a 3lbs dumbbelle and fasten it securely at the top and rear of the sub-frame. You will feel the difference the moment you move the bike.
