darryle, yeah that's how I weigh it. There's car/truck scales out there that you put each tire on and then you can see what each tire /"corner" has on it and then you can for example add the two front or rear tires on a car/truck and it will give you what that axle load is. Then you can add all the weights together and get total weight.
I've used similar weigh scales to weigh aircraft (fighters and helicopters) with pads and load cells. Pretty basic stuff.
If you want, just get your bathroom scale and make a little ramp with some wood or something and roll the bikes front tire on the scale (hold it upright balanced, no leaning it, while someone looks at the number) write number down and then roll rear on and add both numbers together. Then you have front axle weight and rear axle weight. I bet your front will be around 270-280 lb and rear will be around 230-240. Give it a shot and see what ya come up with.
