    +1 on the clutch-less up-shift.

    Although I don't need to worry now I have an HM :D

    great mate, QS is great, bike pulls like a train so much more than before it was set up/ not really played with the different maps yet or TC as I've not had much chance to ride it and when I have it's been set to MAX rather than rain setting.

    if not using the clutch whilst upshifting causes no damage to the gear box why do people spend £100's on quickshifters

    so you can keep it pinned with no rolling off even for just a split second.

    Cheers for this folks. Done clutch less shifts up and down the box on a wide variety of vehicles over the years, Never considered it on my bike though, Here's to Sunday :)

    +1 above.
    There is no problem at all shifting up clutchless as long as you are only using minimal pressure as you roll off the throttle. The next cog will be snicked in very compliantly when you have timed it right with the revs, which quite happily, could be almost anywhere in the rev range with the blade. It's only when you force the gears in, and you'd have to be a right mong not to know you're doing it, that the selector forks / dogs get worn or bent.

    I tend not to use the clutch on upshifts when bobbing along a bit; as said, when timed right it is a smoother action than using the clutch. I just time the lifting of the gear lever with a momentary partial close of the throttle; this action creates a little "slack" in the drive allowing a nice seemless upshift. I have QS on my track bikes & these also work by creating "slack" in the drive; instead of a momentary partial close of the throttle, they cut the ignition (or fuel depending on type), but the effect is the same.

    Argueably, I don't gain anything by using a QS, but the sound as you go through the box with the throttle wide open is addictive!

    I recall reading magazines from years ago encouraging riders to learn clutchless upshifts, especially when carrying a pillion because its a smoother action (when done right). I can't imagine it causes an damage.

    :)

    Because a quickshifter's main purpose is to allow you to change gear without rolling off the throttle.

    Ok i think im going to try this next time im out. so the key point is gentle pressure on the gear lever just as you roll of the throttle ?

    Just change gear as normal, but don't use the clutch. Do it quickly and smoothly and don't overthink it, if you know what I mean. It's often easier at a decent amount of revs, but I often do it as low as 3,000rpm for example.
    Don't put pressure on the lever until you have rolled off the throttle slightly - the gearbox won't like it!
    You can rest your foot under the pedal touching it, but don't pressure it until you actually want to change gear.

    +1 for me, never do it on downshifts tho.
    Pressure under the lever usually selects the gear as you slightly roll off the throttle in my experience.

    Always on up, not from 1st - 2nd though out of habit as the r6 was a little snatchy on that...

    Done down just to see and it's not alot different but not as slick so I don't bother. Plus If you don't have a slipper your going to want to blip the throttle before down shift....

    Again not really an issue on new bikes but just habit of how I learnt years ago.
