Weighing the bike or guessing?

Hi All,

Looking at new fork springs and rear shock. So I'm being asked for the weight of me, riding gear, farkles and the bike wet.

I can weigh myself and bike gear and probably hold a few of the farkles at the same time, but.............

How much does the bike weigh with engine bars and a full tank of gas, do I just go with Suzuki's specs? Suspension specialists say that manufacturers specs are often under the real figure, should I just add a bit of guess-work?

How did you guys do it?

Cheers,

I think Suzuki's published curb weight figures are pretty close 478 lbs non-ABS and 485 lbs ABS. There are many M/C magazines that have tested these bikes and those #'s are pretty close. Now the old Dry weight #'s they used to report were a joke! Dry means not only no gas, but no oil, no antifreeze, no water in the battery, probably no battery itself either, no air in the tires, maybe no tires also. Look up your farkles and see what the shipping weight is. Or you can get 2 bathroom scales and roll up on them and hold her steady.

Fully farkled and tools(tool tube and underseat), tank bag. 550 lbs. on the truck scale. 650 lbs. when loaded for a camping trip.

You actually only need one bathroom scale. You weigh the front, then weigh the rear, then you weigh yourself and add the numbers. That will get you close enough!

Hey Guys,

Great suggestions, thanks!

Pity the bike is laid up or I'd take it to the weigh station.

I'll work with the curb weight and stand on a weighing scale with my gear on and saddlebags + tank bag in hands. Then see how that compares with the farkled weight suggestion.

Cheers,

Anyone have any idea how accurate truck weigh stations are supposed to be? +/- 100 lbs in the context of a multi-ton truck is likely completely irrelevant. I can't imagine that a scale that weighs on the magnitude of tons would be accurate enough for this. Bathroom scale would seem the better suggestion to me.

Edit: A quick google search revealed that at least one Mfgr of scales (Cat Scales) claims an 80 lb accuracy, which is 0.1% error on an 80,000 lb truck. Unfortunately, this is ~20% error on a Strom. Also, these things are apparently designed to work within certain ranges, and become less accurate at the extremes of those ranges (and I think a 450 lb bike would qualify as being at the extreme of the range the scale was designed for.)

The error is probably going to be a percentage, plus a static amount for miscalibration.

Just hop on the truck scale and see what it weighs you at. If it's close, you're fine.

The one near my place does 20lb increments, and it weighs me at 180 or 200, so it's close enough.

Measurement range

The 440 lbs. for my '05 Wee was on a scale at a business that sells dirt, mulch wood etc. and weighs dump trucks, trailers, cars etc. on a scale not big enough for tractors and semi-trailers. The display cycled between 420 and 440 before settling on 440 pounds.
P.S. Didn't cost me anything. I think the lady running the scales liked me.
Keep smiling.
