Excellent! Button looks really good, too. I'm curious to know if you have CC instrument indications, like the little speedo icon on the right instrument face and the green active light.

Five actions should turn cruise off. They are: closing the throttle past the stop; opening the throttle past the current position for the speed you're going; turning on a brake light with toe or hand levers; or actuating the clutch lever.

 

[tsmgguy]

I don't remember exactly, but I think you have to be going 30 or 40 mph for it to set.

Two conditions that must be met for cruise control on with the green active light: speed must be from 19-99 mph, and must be in third gear or above.

 

[tsmgguy]

Yay!

It's on the wiring diagram in the service manual I have as well, but there's no cruise control map, on TuneECU anyway, and it's not listed as an accessory for the Thruxton so I figured it was a non-starter.

Right. The WC Thrux and T120 were advertised at the model launch in late 2015 as being offered with cruise control as an option. CC for the Thrux never came out, and some early buyers were mightily pissed off. All that remains externally visible of CC on the Thrux is the green light on the right instrument face. You can see it in the right light.

After a few early T120 CC kits were delivered, Triumph tried to pull back from offering any more kits. Don't know why they changed their corporate minds. IMHO, only cruise control on the Speedmaster was handled properly as it was installed at the factory.

I think the Thrux might have most if not all of what it needs for cruise control installed at the factory, just like the T120. It's a shame there doesn't appear to be a CC map in the ECU.

I believe that either DRL version should have no bearing whatsoever on adding CC. Those are lighting circuits and should have nothing to do with CC.

Right. The left switch plates are of course different for DRL and non-DRL models. Triumphs CC kit replaces the switch plate, along with the clutch lever housing.

Tahtye modified the original switch plate and retained the OE clutch lever housing, which works fine with CC. I gotta wonder why Triumph's kit replaces both.

I do know that when I tried to replace my T120's original clutch and brake levers with their long lever kit, CC would no longer work. I had to go back to the OE levers.

If you purchased your Bike with no Cruise Control you will have the "Non cruise control map" loaded
If you purchased your bike with cruise control you will have the "cruise control map" loaded
If you have a bike with no cruise control you will have to upload the map with cruise control.
This map is available on the Tene Ecu website.
FULL STOP.

Yeah, I was given a bad piece of information during dealer activation of my T120's cruise control. I understood that activation was the process of enabling the bike's factory loaded cruise control program after the CC kit had been installed. In other words, getting the ECU to "shake hands" with the new hardware and enabling function, with no program download. Wrong.

This statement is accurate: "You can download a CC program into the T120's ECU using Tune ECU"?

All of this gives some hope that the same thing might be done with a Thrux. How much CC design and development went into the Thrux before the decision was made to offer CC on the T120 only? We won't know until someone definitively succeeds or fails in installing it.

 

[tsmgguy]

You can upload an entire fuel and ignition map to the T120 that has Cruise Control software attached. There's no facility within Tuneecu to upload CC on it's own.

For CC on the Thruxton to be possible Triumph would have to release a new map with CC attached. Unless it's possible to copy and paste Thruxton fuel and ignition tables onto a CC map from another bike? No idea, beyond my skills.

Got it, thanks. Beyond my skills, too.

It took only 4 days for the button from the link provided to arrive from the US to here in Italy.
I uploaded the stock cruise control map for my T100 to the bike.
I then installed the button and spliced in the Wires as shown in this thread.
Be carefull on the position chosen for drilling the 12mm hole for the button.It is best to place it as far left as possible as to the right their is a small flange on the underside which will make it difficult for the tightening nut to have room to fit.I had to Dremel a few mm in order for this nut to seat properly.
I took the bike for a spin just now and it works like a dream.
This is a really good mod.
Thanks.

Excellent! Switch looks very factory, like it belongs there.

Hope now that someone figures out a way to add cruise control to a WC Thruxton. My riding buddy has one, and that's the reason for my interest. He'd love to have a cruise control that utilizes what Triumph has already built into the bike. He doesn't like the looks or the expense of the MCCruise, linked here:

Cruise Control for Triumph 1200 Thruxton & Thruxton R Cruise Control TBW

(10% GST will be added in the cart for Australian orders only) The Motorcycle Cruise Control unit is specifically designed for this vehicle. Note that this kit will NOT fit the 1200 Speed Twin. We have been unable to source a Speed Twin to develop a cruise control for this model. If anyone has...

Pictured is Triumph's non-DRL T120 cruise control kit. It replaces the entire left switch plate and clutch lever housing. No original parts are reused, including the bolts.

I looked inside of the connector on the end of the new wiring harness and noticed two new pins. The sockets for those pins were already present in the connector inside of the headlight bucket. The new clutch lever housing, lever, and switch look identical to the original.

This kit took about two hours to install myself using the instructions at https://www.triumphinstructions.com/ProdDocs/A9630248-EN.pdf. My dealer had agreed to activate CC at no additional charge other than the $282 purchase price. There's no need to remove the bike's battery. Just leave the ignition off while you're working. You don't want the ECU detecting missing components and throwing codes.

Some kits replace both the clutch lever and brake lever/reservoir housings. Don't know for sure why that is, but my dealer told me that some T120s were produced without the switch in the throttle grip that you can feel when rotating the grip past the stop. This switch is one of the ways that CC is turned off.

The new switch plate includes new wiring for the left heated grip. The connector for the grip was easy to fish out of the inside of the handle bar. There's no need to remove the left grip for kit installation.

All Triumph really needed to add was the switch cube half that has the switches, along with the added wires and modified connector.

That's what I thought, too. Basically, the kit installs with two bolts and three connectors.

Can't help but notice that none of the switch contacts inside of the left switch plate are weather proofed. There's a caution in the owner's handbook against getting the switch plates wet while washing the bike. This is probably why.

That would be another thing to add to a Thruxton if and when anyone ever gets round to doing a custom program for CC. That switch would be in addition to a push button on the LH side. CC for Thuxton is looking like an increasingly remote possibility.

Making things even more complicated, it looks like the Thruxton S might have the same switch plates as the T120, while they're completely different on the Thrux R. Don't know for sure.

Nice work!

Rats. Now I want one too. It's a completely irrational desire, since I spend 95% of my time on city streets, and when I'm on the freeway there's almost always enough traffic that cruise isn't useful.

And I've got plenty of other projects that need to be finished...

I wanted cruise control on my T120 too, thinking I'd hardly use it. Turns out I do use it, a lot, mostly to keep points off of my license. In the local known speed traps, I just set CC to the speed limit, and worry not.

CC is very unobtrusive. It's easy to set with the single button. Almost anything you do with throttle, brakes, or clutch turns it smoothly off with no jerk. The green light goes off, and you're back to throttle by wire.

To $18! 😁

There are some deep canyons on the interstate north of here. CC is so precise, and the T120 has so much power that speed does not vary by one MPH on those relatively steep grades, uphill or down. CC does a marvelous job of precisely balancing power and engine braking. It's a little eerie.

 

[tsmgguy]

Does the $9 include everything required to update the ECU?

That's about the cost of the switch only, I believe.
