You need to weigh the bike with both wheels sitting on each scale. Otherwise I believe you will get incorrect results as some of the bike's weight will be supported by the other wheel that is on the ground.

---

I can't say I've ever tried weighing a bike, but if you're doing it using one wheel on one set of scales, how does those scales know whether the other wheel of the bike is being supported by the ground or another set of scales...?

I assume you'd need to stand the second wheel on a plinth of some sort, the same height as the scales, otherwise I can't see how there could possibly be any difference.

Since my scales haven't broken yet, I plan to see what results I get weighing one wheel at a time. I'll give that a try tomorrow.

The point of contact is small so there is no overturning movement seen by the scale, so the should be no difference measuring the downward forces, one wheel at a time.

So this morning I gave weighing one wheel at a time a try, while the other wheel rested on the pavement. That placed the wheel being weighed about one inch higher than the wheel resting on the level ground.

Weighing my RS with just one scale at a time, I measured 278 pounds on the front wheel and 280 pounds on the rear wheel, compared with 276 pounds on each wheel when the bike is level and both wheels are weighed at the same time. I assume that the slightly higher weight when measuring one wheel at a time results in the bike being at a slight angle to the ground, instead of being parallel to the ground when both wheels are being measured together. So it is likely that one scale could be used to measure your bike's weight one wheel at a time by placing the other wheel on a wooden board of the same thickness as the height of the scale. (Therefore avoiding the need to purchase a separate scale for each bathroom.)

I have decided not to test my theory at this time. I will let someone else give it a try as I am worried about pushing my luck. When I weigh my bikes I am trying to balance them by hand while looking at the digital scale display under the bike (tough when looking at the rear wheel), which takes a few moments to settle down while I am trying to keep the bike steady and not fall over. That can get a little scary.

Richard, thanks for the info, it's interesting. Your one scale vs two scales is different by 0.7%, I would consider that "no change", I doubt that the accuracy and/or repeatability of these scales is better than 0.7%. It's time to stop risking dropping your bike.

We all know it only matters when you are moving it around on the driveway so what next, does it require a reverse gear like the K1600GT, I think not. This brings me neatly to the fact I test rode a K1600 GT SE today and I was amazed at how heavy this bike is on paper but yet feels no heavier than my RS on the move and for my riding ability it was as flickable through the bends as my RS. The other thing I really liked about this bike was how stable it was at slow speed in traffic, even more so than the RS, this could be my next ride as it offers more 2 up room for the wife.

For those of you who think I should be spending time in a soup kitchen, instead of weighing motorcycles......

Regardless of whether Richard should take up knitting or not, the experiment confirms the rider feeling that the RS is a pretty balanced bike. Given the "bulldog" design of the RS, it does look like it puts its weight forward, and I've been asked by other riders: "is it top/forward heavy?" My response was always: "it doesn't feel that way." Now there is hardcore bathroom scale myth-busting evidence.

"measure with micrometer, mark with chalk, cut with axe."
