Quickshifters, how do they work?

[TUG]

I've had a quick look on teh youtube as i'm more of a visual learner, is there any vids out there that go into great detail on how them tings done work?

Most work on a pressure switch,

When activated, small pneumatic system pushes it into gear quickly, while at the same time electronic system cuts the spark to reduce engine load. Though some are more basic, and still rely on a normal gear change, with a switch or sensor to cut the spark at the same time. They go all the way as complicated as a simple push button

It allows you to keep full throttle on, and change gear without a clutch

Depends on which type you have.

Some have a pneumatic actuator which pushes the gear into place whilst cutting the ignition out whilst others just have a switch so when you move the gear lever it cuts out the ignition.

Basically, when the switch is actuated, it causes the ignition system to cut out which means the spark plugs don't spark. This takes most of the load off of the drive train as it is just spinning due to it's inertia and then the gear is either pneumatically actuated or you click it in as normal.

The principle is that when the ignition is cut so the spark plugs aren't sparking there is next to no load going through the transmission and that is what prevents clutchless shifting.

Think about on your bike, try shifting gear at full throttle and then try shutting off the throttle completely and shifting gear without a clutch. It's likely it will just 'snick' in quite neatly. A quickshifter is the same thing. It cuts the ignition (like turning off the throttle) but does it for around 100 milliseconds to keep loss of power to a minimum.

Cheers! !

What people have described so far is partially correct.

In short, you keep the throttle wide open, hit the gear lever which cuts the fuel or spark to the engine, which is effectively the same as closing the throttle allowing the new gear to locate without damage.

In simple terms

Does it only work changing up then? Normal clutched changes down the box.

Why do you need a gadget to do something easily yourself. You are riding along see red light clutch brake slowly clutch in drop gear, carry on braking drop drop drop.. drop as many gears as needs be and simples you have quick shifted.

That was taught on CBT easiest thing to do, easier than finding the biting point on a newer bike.

I've got the full Bazazz system on mine, FM, TC, and QS.

Once you've had a go of a sportsbike with a quickshifter you'll want one yourself.

Watch how quick the gear changes are, saving you seconds per lap on trackdays, also allows for very smooth gear changes when taking large roundabouts/Corners at speed. ( Not only that but they sound awesome )
