Traction Control - KTM & Husky leading the way
-
@Calum I agree with you, but it looks like this is an RPM control to aid traction and not a wheel spinning control like cars have;
- SO WHAT DOES IT FEEL LIKE? ARE YOU CONSTANTLY AWARE OF THE TC WHEN RIDING?
It’s nothing like the TC systems used on older-style, large adventure bikes (where there’s an audible, stuttery, hit-the-rev-limiter type of interruption to the power delivery), or even the more sophisticated TC system used on KTM’s new adventure models, where the ECU controls the butterfly angle to limit power. The TC system used on KTM’s competition dirt bikes is more of a subtle de-tuning of the power delivery, but only when absolutely required. The system is calibrated so that you can still get the rear wheel spinning-up and the bike’s rear-end stepped out as sideways as you like when the terrain offers consistent grip levels. But in really slick conditions – such as loose rock or patches of wet, soapy clay – it takes the emphasis off the need for super-precise throttle control, and it helps keep the rear wheel hooking up. That results in a bike that consistently tracks straighter, which makes it easier and safer to ride – especially as the rider becomes fatigued.

@CYBER-NINJA I dunno man.
I you want to be a serious MX'er then this is crucial to understand how to get out of that sort of situation. No?
It seems to me it's taking some of the skill needed away from the rider.
@Calum Agreed, but this may be a way for novice or less experienced riders to learn those riding skills more easily? And if they sell more bikes because of the new tech, then it's a wining strategy for the manufacturers. Plus if factory teams start using the TC and win a lot of races then you can bet the other teams will quickly follow suit too? All in all it's a win, win situation if it pays off???
SEDUCED BY THE DARK SIDE!!!

@CYBER-NINJA Oh she'll pay alright lmao!
How much you reckon they'll be knocking these units out for lmao!
- WHICH MODELS DO & DON’T GET TRACTION CONTROL?
At this stage, traction control is only available for four-stroke models. All 2017-model motocrossers from both KTM and Husqvarna come with the technology. On the enduro machine front, TC is standard equipment on Husqvarna’s 2017 FE range and KTM’s Six Days models. However, the system is not standard on KTM’s 2017 EXC-F range, meaning you need to buy an optional Map-Selector Switch (which includes the TC function) from KTM’s PowerParts catalogue for $190.

@CYBER-NINJA Yeah, that's pricey for an ECU mod.
I mean it's literally just a switch that tells the ECU to cut the power if the RPM spikes too quickly.
You now see a lot of Audis running this sort of gear. Electronic Differentials and TCS.
In other words the ECU just senses that the engine is spooling quick and limits the power...what's that restriction?
Always Originate, Never Pirate!

@Calum It's all about reducing wheelspin through rev's, so essentially it's not a true TC or in any way comparable to a 4WD system. Only time will tell if it proves to be a success or not? But you can bet there will be a ton of custom maps and piggyback ECU's on offer with this TC system and the fuel injection systems too. It's all about reducing emissions through the new EC4 laws, which is basically the killjoys attempting to cut down on the 2T off-roaders fun sadly!!!

If you take a closer look at what Transfer Port Injection actually means, you still find it isn't solving one of the major design issues of a 2stroke.
Fuel air mixture is still being injected on the intake stroke, this means that as the compression stroke begins, this fuel air mixture is still being pushed out the exhaust port before combustion, lol.
The only way around this is Direct Direct' Injection, by which fuel is injected after the piston has closed the exhaust port, so no charge is lost. That will keep the 2stroke from dying off for a short while...
Direct Direct injection needs some incredible injectors to over come the pressure and heat during combustion, the complexity takes away what makes a 2Stroke engine still so valued,
2Strokes are grossly inefficient designs, as long as a 2stroke burns oil, they will be phased out from mass market manufacturing sooner than we think. And that is exactly why I love them.
But Snowmobile engines have all this tech already, none of this is ground-breaking!! The MOTOGP 500's from the 90's on were mad fuel injected beasts... complex 2stroke engines don't have commercial value for the domestic motorcycle market,
Hopefully KTM can lead by example! One last huraaah,

@Darty Very informative post, however I think you meant to post this on the fuel injection thread? LOL
Or does it also apply to the Traction Control system as well???

@CYBER-NINJA
I posted then, realised what i'd done... should be at @andrewj1680 thread
