I was curious so I weighed my bike today on a fairly good quality bathroom scale. As you can see I have 20mm ammo cans with some small items inside and a Bestem top box on the back. There is also a tool tube packed with tools, air compressor, etc. On the front there are running lites, handguards, windshield pouch with stuff in it, Pat Walsh skid plate and guards, radiator and oil cooler guards, and misc. wiring and switches. The fuel tank was full.
The 1st time I did it I rolled each tire up a ramp onto the scale which left the other tire about 3" lower and on the ground. I balanced the bike and measured the weight on each tire patch. I came up with 252# front and 322# rear for a 574# total.
I then tried it with the bike level by building a small platform equal in height to the scale for the end not being weighed and I got 265# front and 318# rear for a total of 583# and a front/rear weight bias of 45.5/54.5%.
Now I expect the engineers and rocket scientists out there to tell me why all the above data is skewed because of physics I'm missing. Or is that really pretty close to what she weighs?
