KTM Quickshift

No thanks. Just another thing to go wrong. 

If it "goes wrong" it will just shift like a normal motorcycle... 

Yeah, just like all the linkages and bearings on single shock bikes or the hydraulics of disc brakes or the injector on EFI motors or …

There's a sport for those worried about all the things that can go wrong on a bike: running.

Someone actually bought a new KTM?  I thought KTM sucked ass again?

Can you use Quickshift all the time? I have a 24 350sxf and I haven’t turned it off yet

I’ve used it for about 10 hours for moto.  It does limit power a little had it cut out once, like it without for the 250f

I think everyone is forgetting the biggest advantage . Less arm pump. You don’t have to squeeze the clutch or even move your throttle arm, that could add up during a race. 

Think its good..Dont use it all the time but for fast deep tracks just leave QS on and you can ride like normal but if you need to bang a gear at a odd time its nice to have.

Not sure if it will catch on but think about all the other stuff people said that about (elec start, hydro clutch, Belville washer) 

For a demonstration look up just about any motorcycle drag bike and listen to the seamless full throttle power shifts as they go down the track. Typically a couple 1000'ths of a second ignition cut out and back to full power.  No comparison to manually unloading with the clutch.  Shift efficiency could easily be a bike length on an MX start and who wouldn't want that........

I have it on my 890 R Adventure bike and it's awesome.. I also have a friend who races flat track on a 250sxf and he's killing it off the line with the QS.

I fitted a QS to an old KTM Supermoto bike. It worked great. Made a little ground with every shift on the drag race between corners.

I’ve fitted one to a KTM 690 SM I used on the road. It worked great when accelerating “flat out”, but I didn’t like it at other times, like rev matching on the down shifts - the engine would cut momentarily with the clutch in - which Is completely understandable. I think the “factory” installations turn off the QS when the clutch is used, or can differentiate more accurately between up and down shifts. Test riding BMW GS1200’s the system worked flawlessly, and was promoted as being smoother and reducing the incidence of the pillion’s helmet hitting the riders helmet on the gear changes.

I’ve fitted a Healtech system to my current Supermoto bike, Husky FS450. I have never been happy with it. To make it work at all, the sensitivity needs to be adjusted between road race boots, and MX boots. I think the sensor is to blame, a “piezo” unit under the shifter bolt (The same system that worked well on the KTM). I believe a strain gauge sensor, which fits easy on most sports road bikes, but requires an extra linkage on MX/SM bikes is the better option.

Donut doesn’t have QS and holeshot no problem, so wtf , how is that even possible? 😂

Ok this is an old post but it was new to me, and one of the funniest things I have seen on here 

I agree.

I fit, wire and tune my share of 'quickshift' stuff on racecars, generally when people throw a sequential onto a racecar you'll fit a load cell on the gearknob which sends a signal (or a signal per direction on the better ones) to the ECU for it to briefly (talking milliseconds) cut the ignition and therefore load, along with a gear position sensor to enable different map tables by gear and selected gear display (I believe KTM also have a gear position sensor of sorts).

It is fairly old tech now but still trick stuff and I usually get a kick out of it. Just done one on a gnarly Mk2 Golf recently haha 🤣

I can't see it making any difference to the average racer on a motocross bike, on a motocross track, where you can happily just barely back off the throttle and knock it up a cog. Granted most people are way faster than me, but I don't want it or need it.

Like most I haven't used the clutch to change up on a motocross bike since I first got on a geared 65, and semi-often use it going down. It blew my mind reading on thumpertalk that this isn't standard procedure for some people.

You've got a sequential dog box, just ease up a touch and shift the thing.

Funny you say that. I have never liked KTM until a buddy just bought a 23.5 FE 450. For me that is a top 3 of all time bike.

Very true statement there. But for some of those chasing records, they don’t even run an engine kill. Most transmissions are extensively worked over. 

If you have a 350 or 250 XC-F and the QS is not working take it back to the dealer and get them to update the map and do a QS learning and gear position sensor update. Some were sent out not working including my personal 250 XC-F. I've updated 3 I think. Some of the FX 350's need it also. Not seen it on a SX-F or FC yet. 

I Had them on Supermoto bikes since 2010, allow you to all sorts with gearing, because you can change anywhere and not upset the bike mid turn

Dont see a need on MX , apart from to protect the box from ham footed riders. 

Two riders on identical bikes with identical traction on a straight with gear changes; The QS is going to be an advantage. On a start it could easily be the “wheel in front” that makes the difference. 

In MX, the traction/bumps are rarely identical, but the advantage remains.

A small advantage, but probably more than a Ti Axle, custom engine mount, or electric water pump.

Although I haven't been able to ride since 04, this Quickshift talk has got me remembering two rides that I once owned. One, was a 6 speed Husqvarna 250 CR, which, while slightly underpowered, let me pin it and snick the tranny through the gears without letting off or touching the clutch. Fun bike!

The other was my Muncie'd 66 Chevy II SS. I could leave my 283 at 8 grand while power shifting through all 4. Of course I blew the transmission up, in short order. Not the Husky though. It must've been sequential?

Yepp. Only thing I've missed since selling my ktm.
