rotors/rotating mass question?

I have been considering getting a set of wave rotors for the 1000RR as I cannot afford rims(yet ) and was wondering if the lightend weight of the rotor(s) makes as much difference as what "they" say it does?

I have also heard that it is not wise to run aftermarket carbon rims on the road for reasons like cracking and premature wear, what do you guys recommend for a good light street rim?secondly, and are they worth the money? I plan on streeting the bike for now and then pulling track duty once the money thing gets a little more stable. I have never been on a bike that has aftermarket rims on it but I have played around with a couple of rotating mass things at the toronto science center(or what ever it is called)

Oh and by the way my new Galfer lines(fronts rear and clutch) came in the mail yesterday cant wait to get them on the bike and get riding again(in another 2-3 months )

Re: rotors/recip mass question?

I suspect wave rotors would make a small difference in the moment of inertia. If it were my money there's no way they would make enough of a difference for my street riding.

As for the rims, I'd stick to stock as well. Lighter rims will improve acceleration slightly and make the bike less stable in the wind. You also run the risk of damaging them on pot holes, so you'll have to be very careful riding on rough roads.

If it were my money I'd invest in suspension upgrades.

Re: rotors/recip mass question?

I plan on upgrading the suspension too, but I just wanted to get a feel for what everyone thinks about them rotors and rims, I can remember someone posted a pic of their new '54 rotors and they were very nice. Just wanting to get opinions from the board? you know kind of testing the waters

Your bike sure is treated well for a guy who complains about money so much.

Re: rotors/recip mass question?

My prioritys are maybe a little screwed up...on that note, any one looking for a kidney? things are tight right now, but...I am hoping in a little while, like this summer(?), I will be able to afford some more goodies? nothing really better to do in the crap winter than think of what to do to the bike. pretty much any one in the house will tell you were my thoughts lay most of the time(with the bike). Like I said just trying to get some ideas of what people think about their stuff? nothing better to do

Boy it must suck to live up north. That is, unless you enjoy skiing and riding equally.

Re: rotors/recip mass question?

Shine the rotors they are a waste of $$---any mass saved will be too close to the axis of rotation--so dont expect any real gains. Marchesini has some nice forged Al wheels for $1,700 (see Dan Ks site)---for street duty, I would use Al an eliminate alot of potential headaches.

BTW---its rotating NOT reciprocating mass for wheels

Re: rotors/recip mass question?

I used to do the skiing thing a lot more, but I figured if I am going to spend that much I may as well be warm doing it the damn bike takes all of my money now... I guess that I could spend it on worse things right?

Thanks, that is what I kinda wondered, I dont ride hard enough on the street to see the "added cooling benefits" that they supposedly offer. As for the rims I would like he carbon ones, cause they look hot, but...that is just asking for trouble I think? Anyone changed rims? how noticable is the difference? I have read a few reviews in some mags(not a common mod in the mags though?) and they really seem to like them?

Re: rotors/recip mass question?

Suspension would be on the top of my list as well. As far as wheels go, I have the OZ forged aluminum rims. They are lighter than stock, but not as light as the Marchesinis or others. The advantage, though, is that they're DOT approved, so I'm hoping that means they'll hold up to the occasional pothole. They also use the stock cush drive. The bike steers lighter with them.

Re: rotors/rotating mass question?

For a streetbike and an owner with a limited budget, I'd say none of this (wheels or brakes) is warranted. Just ride it and have fun.

Re: rotors/rotating mass question?

Fun is never a problem
I am thinking that (hopefully) I will be able to convert the RR for the track and get a something a little more touring oriented for the road? Every one seems to want a busa these days? maybe I will jump on that boat (not likely )

The whole convert the RR plan will depend on how far I am to the tracks and what I can pull with my prelude trailer wise?

I am hoping that in the next couple of months there will be better positions opening up at work that I will be qualified for, so that is why all of the questions about the bike gear.

Re: rotors/rotating mass question?

My buddy runs the BST carbon wheels on his GSXR1, it is primarily a trackbike, but he does ride it on the street. He has returned two rear wheels as they had something rattling inside, then a BST came apart at a trackday destroying a $25K Ducati---heres the threadBST Debate . For street, ocassional trackday, there is just too much potential for CF to come apart I know it will incite a huge debate, but for me I would get 16.5" forged mags for my racebike before screwing with CF---for a streetbike forged Al is fine or better yet keep the stockers and get Ohlins front and rear--cost is less than the bSTs
