How do these front rotors work?

[Devaclis]

Looking at these front rotors, where is the friction area? I noticed that the spokes run almost the the outside edge of the rotors, so where do the pads apply pressure?

OR, is the front portion that I can see just a cover for the rotor?

Spokes are in a shield on the front half, not on the rotors.

Rotor is visible only from 6 to 9 o'clock in the pic.

Perfect. Them bastages had me thinking again. You know I am not a big fan of thinking.

What's up with the exhaust, is that 2 different exhaust ports?

One on the hanger, one cut through the side of the belly pan?

The motor is a V-5, and IIRC there is one pipe for the three cylinder bank and another for the two cylinder bank.

Knew it was the RCV, but thought they ran a 5to1 exhaust.
The lower one is for the 3 cylinders, upper for the 2, or vice versa?

The lower looks like a straight megahorn with no baffling compared to the upper can.
I'm sure they've tuned them for performance, just can't wrap my head around the difference in backpressure they look lilke they'd produce.

arent the two bottom pipes straight from two cylinders, then the bank of three actually go under the tail to a sinlge?

:lol: OK, I'm officially confused to the retarded state as to how they have this rigged.
Found some other shots of what I think is the same bike (Maybe prior years) and it appears to run one can.

Someone straighten out this bag of snakes and explain this to me (in very small words) or it's gonna bug me the rest of the weekend.

qoute from your article reference:

"The complex titanium exhaust system ends in twin silencers, one in the seat unit and the other on the bike's right side."

Short version: Different exhaust tuning, depending on what track they are at and how they want to make power. They can vary pipe diameter, primary length, and collector configuration to significantly change the shape of the torque curve, as well as peak power and rpm. Add to this the options they have for fuelling, ignition tuning, cam timing, intake tract length, and airbox configuations, and you get some idea why some teams have a dozen honest-to-God engineers at the track every time the bike turns a wheel! :shocked:

OK, I think I figured it out:
1) Lower exhaust
2) Mid exhaust
3) Undertail exhaust
4) Rider exhaust.

Simple.:wtf::think:

Here's a good shot of the 2004 version, a 5 into 4 (before that it was 5 into 3):

Casey, Jim, Dirk...thank you all, I can sleep tonight.

This is the 5 into 3 version:

Christ...and I thought 2-strokes jacked with exhaust configurations.
