Brake rotors

I have a question about brake rotors. You see the full rotor and you see the ring type rotor. the ring type is about 2.5 inches wide . Is it as effective?

the larger the diameter the more leverage the rotor has on the wheel.so the diameter matters more than how wide it is.

Believe what you refer to as a ring rotor is usually called "floating rotor" & its "swept" area is seperate from it's "carrier". They are usually thinner & lighter than 1 piece rotors & don't "bell" (distort) as much w/extreem heat. As Leon says, larger diameter provides better braking & heat dissipation. luck G

When comparing the old style brake discs (1970's) to the newer style brake discs (1990's and above-generally)there are 2 different style "bands". The "band" is referred to as the area where the brake pads contact the brake disc (also called "swept area").

The 1970's style discs have wide "bands". The wide band discs use the height(top to bottom) of the brake pads to contact the disc to slow the bike. The wide band discs are generally thicker.

The later style narrow "band" discs use the width(front to rear) of the brake pads to contact the disc to slow the bike down. With the narrow band discs, MFG's often use multi-piston calipers with pads that have more surface area than the old wide band discs.

The newer "ring-style(?)" discs are alot lighter and displace heat alot faster than the old thick discs (as pointed out above)

I know this is a very old thread...

But I noticed that "The Fish" log in about 2 weeks ago...


I am looking for an upgrade for a 1998 KZ1000P-17 with 18" wheels

What rotors are these? They look like the Ducati SR4 but those are 320mm...

The Calipers are the TLR Hayabusa and older GSXR1K Tokicos?

And, Do you sell those brackets?

Thanks

No free lunch. Less rotor mass means they saturate with heat faster which is where they start to fade. The thinner ones also warp much more easily. In the old days (80's) cars had heavy cast iron rotors. Loved them. They cost $16 new, very cheap to make. Never warped.

Now the focus is on squeezing every ounce of weight out and hence the magic of lighter rotors (to save fuel). On cars, they use dual disc "hollow" rotors with air holes and all that crap. Less rotor mass relies on constant airflow to remove the heat.

No free lunch.
