Honda CX500, GL500, CX650 and GL650 Comstar Wheel Weights

What’s the weight difference between the Honda CX and GL wheel variants?

The bare wheel weights are done without any brakes attached (apart from the integral drum on the drum brake models) and with the wheel bearings in-situ. The final drive flange has also been removed from the rear wheel for the bare weights.

Got a weight we don’t have? Hit us up at the contact page and let us know.

Here is a photo of three of the CX/GL wheel variants - the Comstar, Reverse Comstar and Boomerang Comstars.

Why care about this anyway? Reducing unsprung weight is one way of improving the bike’s handling, and one of the ways we can achieve that is by using lighter wheels. It’s one of the things I actually get regular questions about, so here it is.
