HSTC and ABS (on/off) - 6 speed (standard) model

I am seeing different opinions about wether ABS (on/off) and HSTC will be part of the standard (6 speed) model. The wording on the Honda web site is a bit vague. Anyone know for sure?

Also, does anyone know how HSTC works? My understanding is that it somehow regulates torque going to the rear wheel - thus controlling wheel spin. Does it work through a slipper clutch or/ fuel injector mapping or/ variable valve timing?

Just killing time watching the parade and waiting for Thanksgiving dinner - Happy Thanksgiving!

Thanks for the reply.

I ordered mine in September with expected delivery date in December, but they already informed me that go be available only at the beginning of January.
My version is without ABS and I think it is not binding in Portugal. (I can not imagine having a bike with ABS)

I have been unsuccessful in finding the details of the HSTC as it applies to the AT. I think it will be a full function traction control that is rider programmable. In the Dec/Jan issue of Motorcyclist magazine they rode the new Honda 213xxx super bike that has HSTC. The article went into some detail explaining that it was the Bosch IMU- inertial measurement unit that measures acceleration in all axis's. It feeds this data to the ECU which is also sampling wheel speeds and engine parameters to only allow enough torque to the rear wheel so that rear wheel spin up/drift will be limited or controlled to some defined limit. I am waiting and searching for confirmation or better info.

It's pretty clear on Honda Powersports (USA) https://powersports.honda.com/africatwin.aspx that the AT will be: "Offered with either a six-speed manual gearbox or a new DCT transmission with selectable on- and off-road modes, both versions have ABS standard with rear ABS on/off and Honda Selectable Torque Control (HSTC). "

"Torque control" is a curious choice of names since TC systems modulate power to the rear wheel to control slippage, or traction. Anyway, traction control on motorcycles uses the ECU (through ignition timing, fuel delivery or throttle position) to adjust the engine speed so the rear wheel is turning at the same or pre-set (per rider choice of level) amount faster, than the front wheel. The AT will probably get a three level TC (as the Crosstourer) plus OFF.

I imagine that because the Crosstourer is a 5 year old design and Bosch IMU has only been out (for consumer motorcycles) a year or so, it's a little late for the CT. At present just a few high dollar BMW, Ducati, Yamaha (R1M) models have it - nothing costing as little as the AT's $13K US. So don't expect it at that price level for a few years. But, if it's as good as it sounds (Bosch says every kind of riding - dirt riding to race track can be made safer with IMU) , sooner or later consumer demand (if not legislative action) will make it available for most bikes.
