Faster with ABS off ??

[beaver]

Just been out for a quick 75 mile blast this morning, and playing about with the ABS and lifting the front a tad etc... all good fun.

Anyway, when opening the bike up on the straights and twisty bits, It is noticeable how much faster they are with the ABS turned off.

I guess with it on, each time the front even bounces, the rear is trimmed to keep it in line... turn it off and the rear gets what you intend to give it

It’s the traction control that keeps the front wheel down if you gas it too much

I started a thread about this a few years ago. It was quite entertaining!

The lc gs is the only bike i have had with traction control,
there have been occasions where i felt it was holding back but noticed the tcs light flickering,
There is more urgency with Mother switched off , but it is on you to judge the grip,
Allready had the rear spin up on the abs r 9t when making progress,
The new abs tcs is a clever set up,

I can imagine... they will be lining up as I type
.

Its the first bike I've had with traction (did the TU have it?)... all the rest I've judged myself... got to say, its scary to see some riders in the wet trying to get their leg down... obviously hoping traction works for them LOL

but it must hold it back quite a lot... with it off its a whole lot more fun to ride around the fast 'B' roads

Never, ever had TC until relatively recently. Never missed not having it, even when I didn't know it even existed! Whilst it has obvious safety benefits (eg rain mode and abs), there's no substitute for learning bike control and reading conditions/riding accordingly. I consider it a bonus, not a necessity. A nice to have but also nice to be able to switch it off.

it is good off for sure... never realised how much it holds you back!!

Traction control is amongst the "help" features that where still allowed after the newest regulations in MotoGP where introduced, as it is regarded as a great help to prevent highside accidents.

If there is a need for limited slip, may I suggest using the Dynamic Pro mode. This mode allows for slip of the rear and limited wheelies, yet maintains prevention of heavy slips that causes an accident.

do you know the parameters of the "limited wheelies",ie degree of lift allowed by the imu?

I think you can get the front fairly high but then it will kick in and slam the front down

At least that's what happens on my hypermotard

not very smooth and controlled then

To be honest, I have not tested the wheelie feature on the BMW.
The older ones (pre electronic throttle) used to act that way, they just chopped the ignition.

My -15 GSA TC reduced the throttle input to the verge of slipping, you only noticed the yellow flashing light and slightly loss of power. I have noe experience with the low wheelies… But since the frontwheel is not touching the ground, the TC needs to make sure it stops the rotation without feedback, so I would expect a bit rough landing....

Don't have it... maybe this is why I find it better off

So... What you are saying is that you need an upgrade

 

[RedRick Esq.]

Nope

All looks good as it lifts but then slam

I put it into race mode for the full effect but it does get a bit scary sometimes

Don't think they could... I've no ESA either... its all manual my end but probably does explain where I find it better off if your Dynamic allows you to play more...

I don't know the year of your bike. However, the first couple of generations of TC was merely a safety feature, "better safe than sorry" was the main objective, and the only way to intervene quickly was to chop the ignition.

By introducing the e-throttle this gave the manufacturer of such systems way more playground. Watching MotoGP a couple of years ago you could see riders doing fat rear wheel slides. Then, after everyone were forced to use the same ECU, the power slides are more or less history, this is probably due to a less sophisticated TC.

Our bikes aren't there, but it shows what may be possible.
Even so, even on streetbikes (and I don't mean BMW in particular) the TC systems now have become rather good, and I would be surprised if anyone would feel the Dynamic TC slowing them down on systems found on Ducati, KTM and BMW (and probably others).

BMW calls it the PRO modes, i.e Dynamic Pro and Enduro PRO, where the Dynamic PRO as well as Enduro mode will allow you to do limited wheelies, and in Enduro PRO you are totally free to embarrass your self.


But we must bear in mind that we are riding a street bike, so even now BMW states:

Quote Riders manual, describing the current system as of 2019:

The system is not optimised for
special requirements that apply
under extreme competitive situations
off-road or on the track.
The BMW Motorrad ASC can be
deactivated in these cases.

When i had my S1000XR i found it to be a much faster bike point A - B with the traction control on than if it was disabled into track mode ( or whatever it was called) mainly because speed was lost trying to get the front back on the floor when coming out of bends or dealing with the back end breaking away

I might just be a big cowardy custard but in terms of jorney speed less time lost with the TC on and less underpant soiling as a bonus

its a 2015 bike.. maybe my initial quote of 'faster' is not that accurate as you say, as keeping the front end down will make it faster in a straight line for sure... madybe faster should be replaced by some other descriptive word
On my mode's I have Road or Rain.. thats it.. so I guess in turning it off, I'm riding more like your dynamic setting (but without the backstop)
works for me anyway.. I will be turning it off on the odd occasion now when by myself and the conditions say play

You'll have to install the encoding plug in order to get the full benefit of all the systems.
