    AGH-AIN??? in this forum you can find at least a dozillion threads on this...
    i'm getting pretty confused: what the rear brake has been proved guilty of, down there???

    just think that Stoner had a ventilated disc. on the rear wheel. why, if it's so useless?

    ehm... actually... open throttle and your ass goes UP, THEN the front fork will raise. but the rear goes up first...
    the rear goes down when you brake, right as you said before.

    and that's the reason why you should open throttle while turning...

    This usually means the rear of the bike actually RISES..... unless something else is done to the suspension or geometry to prevent this from happening.....
    exactly.
    more over, it happens also because the pivot is usually higher than the rear wheel axis. remember rear wheel has action and counter reaction on the ground contact point and its axis. the bike goes up like the swingarm was an idraulic jack...

    you're confusing apples with pears as we say...
    rear brake is needed to balance your chassis geometry and helping you to get maximum breakin power from the front wheel.
    slippy clutch has another use, which is not to have the rear wheel locked (with the following slippy and shitty control while you're leaning the bike) if you downshift too quickly, or equally not to have the engine rocked to the limiter if the rear wheel doesn't slip...

    so yes, it's still useful.

    I believe Nonda has experimented with dual/linked brake systems? So there must be validity in the use of both in tandem.
    honda has more than experimented. they sold combined braking equipped bikes for years.
    i kinda hated it.
    it was a mechanical (well, hydro-mechanical) linkage that connected front and rear calipers.
    it was effective in reducing the front pitch down, but it always seemed to me a little... "late" in its functioning.
    i'm pretty happy they discontinued it, even because nowadays it's way simpler to implement such a function through abs...

    no you can't.
    and i don't know you personally nor i am questioning your value as a racer.
    i'm only sure you can't.
    i can give you the benefit of doubt ONLY if you're talkin of 25 lapses in a race.

    if otherwise you're trying to tell us that you're capable of maintaining that amount of focus and stress 24/7/365 for the 100 years i wish you to live on a bike, then know you simply are not.

    It represents one of the largest (if not the largest) gyroscopic forces on the bike, therefore it really doesn't want to lean over. This is irrespective of its contact with the ground.
    remember the rear wheel has a degree of liberty less than the front.
    gyro effect of rear wheel is what makes you turn (together with rheonomic reaction, that's the grip of the front wheel on the ground...).

    ducking now
    you'd better do...

    I usually use both on most occasions. But it might be down to a bad habit I formed by owning bikes with shitty tyres. (Grab the front brake too much and you slide out of control).

    Yeah good call. the kind of races that lightweight was entering only did about 3 laps, 6 at most. Quite a few corners mind.
    Don't you look at my accountant.
