To make a long story short. There is no way I can get another bike out of various reasons. Plus I would never get any decent money for my beloved 11 year old.
Now last Year I put Marchesini Ultralights on my F4 and the handling improved dramatically, as might almost every one would have imagined.
Recently I bought even some Moto Corse titanium mufflers.
Now I think I will try to improve the old gal further.
We speak a lot about unsprung weight.
So what is the weight of stock 310mm rotors ?
What is the weight of the stock rear rotor ?
What is the weight of alternatives ?
Your input would be really appreciated and is might interesting for fellow riders.
Wow that was quick and really detailed, thank You very much !
This is in deed enlightening and astonishing.
The summary is that You can't even save much weight unless You have an older bike.
My F4S has, according to the Manual, steel flanged 310mm discs.
Swopping them to F4 1000S 310 mm alloy flanged discs is saving around 750 gr or 1,5 lbs.
This is in my eyes probably the way to go than.
Everything else seams to be weight wise pretty much in the same league.
I agree, in your case getting the F1000 rotors is the way to go.
It's kind of like having an F4 with the oem Brembo Superlight wheels, you can't get much more weight reduction even if you get BST's.
Of course you could the carbon rotors route, but they would cost almost as much as your F4 750 :stickpoke
Tree, just for the heck of it. Post the weight of composite Rotors here.
They can't weigh nothing I imagine. At least not a 5 to 6 lbs weight saving as I read in other posts.
What is out there on alternatives, besides the options 999 posted.
I saw Armstrong discs for an example.
How about Carbon and Ceramic is this on the market ?
However I don't plan to build a track weapon.
I just want to improve my bike for road use, and might an occasional track experience in the future.
And there I think is steel still the best solution.
These are the ones to get. have to dry off after they get wet (washing bike or resting after being in the rain) as they'll rust. Great bite, great feel, great price!
Motowheels has them in SS too. http://motowheels.com/c-181203-parts-brake-rotors.html
They have a matching rear rotor as well, but you'll have to grid a bit of the rear bracket down for it to fit properly (easily done, comes with instructions).
I have a pair of stock 310mm rotors from an SPR and a pair of 320mm rotors from Brake tech and they weigh exactly the same: 1417 grams each.
