Any reason for an aftermarket quick-upshifter?

[snagzie]

As title, wondering on views for paying for an aftermarket up-shifter?

I've recently discovered clutchless upshifts (i.e. just roll off for a a fraction whilst upshifting) and now can't see the point of the add-on when they cost several hundred quid when I think all the QS will do is essentially the same thing as what I'm doing already (i.e. kill the throttle for a split second when it senses the gear lever moving)

I know you can get blippers but my particular bike isn't ride-by-wire so can't get one of those so I am informed.

Cheers

It's personal choice, a quickshifter is different to a clutchless gear change as you have to roll the throttle, with a QS it's a lot more fun but in reality unnecessary on the road but I like them and have fitted aftermarket ones to bikes that don't have them as standard.

I fitted one to my GSXR race bike. Healtech do a decent one for around £200. All the parameters can be set using Bluetooth, and it was a very easy install, as it just piggy backed off the fuel injectors.

On the road it's little more than an amusement, but riding quickly on track I found uses for it. The bike was less unsettled changing gear while accelerating out of long fast corners, and not having to adjust my right wrist for roll off was great.

That said, I found it slightly detracted from the enjoyment for me, in much the same way as a DSG box in a car is quick, but not as mechanical or involved.

A warning though, I set the timings a bit too quick for the fuel cut off, and ended up grinding away a little bit of second gear, oops!

Yeah this, my current bike has a noisier gearbox than it should, no idea why

I have 1 bike with a Translogic aftermarket QS...it also has GP shift (1 up, 5 down)

I have another with a standard OE quick up/down shift.

I think they're pretty pointless on the road.. apart from the full throttle change noise.

Apart from that, clutchless upshifts are pretty much the same for me....and I still prefer my manual downshifting/blipping.. I think I'm pretty good/smooth and feels better than the bike doing it.

On the track... yeah, I can see the point.

[snagzie]

Yeah as I thought really. Yeah am aware that for clutchless upshifts you have the extra faff of rolling off but still not an issue compared to pulling the clutch in.

Had a QS (up) on my K1300S and I assume it was just doing the same thing I mentioned before.

I think I'll just live without a QS until I can get a bike that can have a blipper; I'm happy enough manually blipping the throttle, never known anything different!

Just a bit of pedantry- the Healtech QS does nothing for fuel. It’s ignition cut only.

It also shouldn’t be used 1st to 2nd which may have been your problem because the ignition cut duration is not configurable by gear just rpm.

Just to add further pedantry! In most cases you are correct, but certain older bikes use a different set up where it cuts fuel, the harness mounts directly onto the injectors.

As for second gear, the manual said it's fine to do as long as first-second shift feels smooth on your bike using the QS.. which it was, until it wasn't! Should have known better, its a common rule of thumb to always use clutch between these gears, and i always did prior to the install. Either way I crashed the bike next outing, so that was that

Love the factory fit up/down QS on my MT09. I think the comparison to a DSG is a fair one. I'm a bit wary that too much use of it will hamper my learning proper gear changes, especially as this is my first bike. That said, using it and not using it are both fun methods for different reasons so for the most part I change gear "properly".

Thought they were a bit pointless on the road, until I bought a BMW with shift assist upshift. Then thought clutch less down changes were a bit of a gimmick. Bought a Ducati with a up/down quick shifter/blipper, and now I like it.

I had a Translogic on my K1 750 and a bazzaz on my K6 750 - the second one was part of a crude TC system/mapping on the bike too

I've ridden plenty with and without and would always prefer to have. I can live without a blipper but a QS is really nice for faster road rides and track

This is my thinking, I actually enjoy using the clutch etc. plus, having just had to replace the gearbox in my Monster due to a broken 6th gear (not caused by clutchless shifting I hasten to add), I'd like to do my best avoid future gearbox problems...

Ridden one that shifts down too? Late braking and shifting down 3 gears in a second, without using the clutch, is just as good.

So is it common knowledge/behaviour to always use the clutch between 1st and 2nd on any bike with a quickshifter? I tend to do that anyway but just wondering?

I was out today and went 1 to 2 fine (just clutchless) so I'm assuming the QS would be fine too

550mile old suzuki though so YMMV

[Supercilious Sid]

I've got one of these on my R1. It's getting on a bit but button shifting is great fun.

The issue can be getting neutral, instead of a gear.

Watch the BSB bikes at Cadwell park as the fast riders go first to second at the chicane just before the left hander to the mountain 'cos if you stand in just the right place you'll see air under the rear tyre as it unloads during the upshift!

I have a Translogic on the FrankenTrumpet and always use the clutch 1st to 2nd.
