New lightweight rotor
Check it out boys, just purchased a seriously lightened rotor (about 3/4 of a pound lighter from what I can tell based on a quick Google search). Looks quite trick too!

Bought it (it`s the rear unit) from a chap in Toronto, he got it machined by a place called C2 (?). He is also selling a "Swiss cheese" version (http://www.speedzilla.com/forums/hon...ar-rotors.html) While not an astronomical weight saving, it all adds up (along with AFAM 520 pitch aluminum rear sprocket and magnesium PVM rim). Reduced unsprung/rotating weight = improved suspension action, handling and acceleration. No downsides to that (other than the $$$$$)

The further from the axis of rotation the more effect it has (from an inertia standpoint). In terms of unsprung weight, it doesn't matter where it`s located. Either way, 3/4 of pouund is 3/4 of a pound am running a 180/55 BT-016 tire which is decently light too)

I did it to, but I went the free route and drilled my own.
I asked my waterjet guy. He sais he could cut rotors no problem. I may start a service where you send me your rotors, I have them cut, and I send them back.

Bolted it up last night and went for a quick ride. Braking power is softer than before but I hardly use the rear brake anyhow (guess I'll never be a good cruiser rider then, lol). One the positive side, it means locking it up inadvertantly is almost impossible (a good thing, especially on wet pavement). Oh yes, and it looks wicked too

What about warping and possible cracking? It looks like A LOT of area has been removed.
What happens if this fails in traffic? If someone goes down and is injured or worse because of a broken rotor I can just imagine the law suit...

I live in Canada, we are not quite lawsuit central yet (with all due respect to my American friends). Besides, as I mentioned earlier, I hardly use the rear brake at all (its only use is to stabilize the bike in some circumstances, hardly taxing enough to cause it to fail). Catastrophic failure of the rear rotor is very far from top of my list of worries....

Man, you've got some serious work into that bike. Looks like the whole motor has be crinkle coated (not to mention other bits here and there) - true? Difficult to keep clean? Are those mirrors effective? About the same as stock? (Ooops! Thread hijacking - my bad.)

Not sure as I didn't weigh them , or the stock ones for that matter. I can tell you that the PVMs are MUCH lighter (the front, in particular, is ridiculously so). Just have to steer clear of potholes, an on-going job here in Quebec....

I have seen shops adverstise on eBay that offer this service and create some really nice rear rotors (albeit they look a bit heavier than my new one, he he) Do a quick search and you'll surely find one

Yeah, I have used wrinkle finish paint on the engine. I think it is a good finish and easy enough to keep clean using something like what we call truckwash in Australia. It is a detergent you mix up, spray on, and hose off after a while. I think if you were to wash it by hand you could only use a sponge so as to not mark the finish.
The mirrors are a custom job I did myself, using a combination of the Honda mounts and an aftermarket mirror. Bastard of a job that took ages, but worked out in the end. Visibility is a bit better than the Honda mirror as they are a bit longer.
Sorry for the thread hijack!
