Bike weight

[Rob S.]

I know it's possible to calculate a vehicles weight with the tire pressure and contact patch, but has anybody put a bathroom scale under the front tire and then the rear?

I have a thin digital scale I'm thinking of trying that with. Don't worry, it's an American scale - it's just getting warmed up at 250!

I've done the bathroom scale thing. You have to make sure the opposite wheel is on a piece of wood or something to get an accurate measurement though (so the entire bike is level when on the scale).

Great way to get a curb weight of the bike, but remember your weight geared up is distributed differently on each wheel too.

I was thinking about doing it in two steps - front and back. From what I remember from my old truck driving days, that's how the police with portable scales at weigh stations did it.

Yeah, that's what I meant. Front wheel is on the scale / rear wheel is on a piece of wood, and vice versa.

That's correct, but Big Rich is just suggesting you use a block of wood under the opposite end to keep the bike level. It affects your results a bit if you just tilt the bike to put the scale under each wheel.

If you know anyone who has racecar scales you can weigh it like I did mine.

Now I understand. Thanks.

Akckhim - how many pounds?

[akckhim]

465 pounds

465 pounds

That is really light, how much did you save with the GSXR engine and suspension components?

Forgot about the side stand.

So will I have to weigh it at three points?

No, just balance it upright on the wheels with as light a touch as you can manage. That way you get the front/rear split and the total. If you can get the same numbers with you on the bike (have a buddy balance the bike while you sit in your standard riding position with gear on) that would be great to know as well.

Stock weight for this bike was 504 dry so at least 40lbs lighter. Here is a good comparison my 94 gsxr1100w has a stock dry weight of 509lbs. A 2014 gsxr1000 has a curb weight of 448lbs a Hyabusa is 550lbs dry. So yes its fairly light, and im happy with that.
