Maybe for casual street riding the brake are adequate. That being said, the word "adequate" doesn't exactly translate into steller. The 1098 brakes are an entirely different story. Do you realize the 848 comes with the same calipers that are on the 696?

Have you ever ridden an 848 at the track? I have and believe me the brakes completely suck ass once the pace heats up. After two laps the brakes began to fade and I couldn't hit my markers consistantly without fear of going into the turn too hot. It doesn't exactly exude confidence.

Yep, I rode my 848 at Pacific Raceways, Oregon Raceway Park, and Miller...all in the intermediate group. I thought the brakes were fine, even slowing down into turn 1 at Miller from about 160 mph (indicated). Two fingers was all I needed.

The 1098 brakes are definitely stronger, but damn, what other bikes even have monoblock brakes like that? I really doubt the 848 brakes are worse than any of the Japanese bikes. Who cares if they are also on the 696...they're definitely overkill fo that bike.

The brakes on my 748 are fine as well, and I ride it much harder than the 848.

Maybe your pads were glazed or something? Short of racing, I don't see how the 848 brakes aren't just fine. If there was a problem, then new pads would for sure fix it.

I'm not the only one to have this opinion. There are a few folks that work at a local dealer who feel the same way. And no, they weren't riding the same bike as me.
I've been wallowing in my own chaotic and insecure delusions.

Easy upgrade.  ;)

Ducati Superbikes have always been famous for their incredible, track-derived braking performance and the 848EVO  is no exception. Now featuring radially mounted Brembo's powerful Monobloc calliper racing tachnology. The twin Monobloc callipers each have four 34 mm pistons that grip 320 mm discs to help generate planet-stopping braking while transmitting a precise “feel” at the brake lever. On the rear is a Brembo two-piston calliper and 245 mm disc.

Producing a front subframe in magnesium underlines the attention to weight-saving detail in the Ducati Superbike range. Its construction provides secure support for the headlamp, instruments and fairing, and the weight-saving around this high, forward position contributes considerably to overall "feel" and control of the machine.

From clutch & now brakes ...... next it will be about the rear-sets, OK ;D

here's the open clutch on my streetfighter.  it's much louder, but the cooll factor is worth it and you won't notice the sound when you're screaming down the road.  warning, the stock springs will get rusty.

I am looking at getting a 2002 S4, the dry open clutch is awsome looking.

Quote from: D PaoliIt spins differently when its in gear vs idle.
what do u mean???  ???

When the bike is in gear, the clutch is connected to the rear wheel mechanically, so part of it moves with the rear wheel, including the pressure plate.  That means if you're stopped, then it's stopped, and if you walk the bike forward, it spins backward along with it.  However, if you're in neutral with the clutch engaged, it is mechanically mated to the engine and spins in proportion to engine speed.

Open clutches do let the clutch dust out. If I ran my MTS closed, the clutch would start making a moaning sound right at take-off after about 3K miles. I'd have to remove the cover and blow it out with air to make it quit. Didn't seem to affect performance, but it was annoying.

When I switched to open I never had to do that again.

I've run my dry clutch open since almost day 1 and I have the "moaning on takeoff" sound, which started around 8,000 miles, so I doubt it's actually tied to any dust issues specifically.

I often get the response "Is it supossed to be open like that?". I'm never quite sure how to answer the question.

Closed, open, slotted cover, half cover, stock cover with the brass grommets used as spacers....

I've run the clutch every which way, and every configuration has its charms.

Go with whatever works for ya.
