Topic: Weight of wheels

[beemerbum]

I have replaced the steel wheels on my '77 K7 750 with aluminum wheels and hubs from a 750A. Just curious.. anyone know how much un-sprung weight I have eliminated?

Interesting question, but I think you are one of few who possesses both kinds of wheels, shouldn't you have weighed them before mounting?

One would think so. I have never been accused of thinking ahead logically. Both front and rear were e-bay items that have been re-spoked. I am left to wonder why Honda never mounted the aluminum rims on the 750K.

Cost is the answer

I recently weighed a stock steel 19”x1.85 rim versus an 18”x2.15 Excel rim. The weight difference was 1.4#. Less than you’d think is my answer.

I can believe that. Just lifting the wheels, there doesn't seem much difference in weight. The appearance however makes them look so much lighter

Excel may weigh more than a did alloy rim.
 An  Akron shoulderless  would be way lighter than an Excel..
 But they look better than steelies....

1.4 lbs makes more of a difference when you spin it at 60mph

Even more at 120mph

Skipping the fries, coke, late pizza and pasta meals might make a bigger difference

I was trying to find some weights last night, found out Excel makes a lighter series.. I didn't know that.
