Hmm might have to look into this for my new track bike. Something similar was done to my old 2007 GSXR 750 track bike (prior to my purchase).

Sweet, did you have a chance to weigh it?

No, I haven't gotten it back yet, the photo is from Skip. Should have it in a week or so.

I understand the significance of reducing rotational mass and unsprung weight, but can you guys honestly feel a difference with the slightly lighter rotor? Does anybody have any empirical evidence to back this up? I'm not talking trash, just genuinely interested.

No, most riders can't feel a pound taken off the back, but it all adds up. Drop more weight going from a steel sprocket to aluminum and a lighter chain, and I bet most could feel all the weight taken off the back. Lighter wheels are also on my short list and I see no reason to spend ~$3k on weight loss without first spending $75.

It also looks effin' sweet.

Gotcha. It looks badass dude. I'd do it purely for aesthetics!

I've got an email out to Skip now. Hoping to get this done before track season rolls around.

Just got mine back today, 1 lb, 5 oz. That's over half a pound lost, which is about what I was expecting. Pretty stoked for such a reasonable price.

Awesome! Every little reduction makes a difference. Plus, it just looks better.

Along with this, I've got captive front/rear spacers and my dad has a pretty serious mill that I'm going to do my own captive rear brake caliper bracket mod on in the next few weeks.
