Folks,

Has anyone installed the ST2 Smart Turn System on the Tenere? They want you to follow the wire cable from the turn signal switch to the connector block. Well it doesn't seem to be that simple as the cable disappears into the neck and appears to come out on the right side of the fairing around the battery and fuses. Well there are 3 sets of terminator blocks and I can't seem to determine which one is the one I need to cut and splice this controller into.

Every one of my Yamaha Ventures since 1983 has had self cancelling turn signals, and it's driving my crazy that Yamaha can put cruise control and every other electrical convenience on a FJR and Super Tenere, but not self c ancelling turn signals. Why even the old Honda Pacific Coast had self cancelling turn signals?


If someone has already installed one of these on their bike, could they help me out...please.

Thanks,

Rick Butler

I too am interested in this subject. I've got a smart turn system sitting on my bench that I have not had time to yet install.

My 82 Yamaha Seca 550 had self-cancelling turn signals. ::009::
My Seca 650 did too and they worked well. It's funny that no bike I've owned or ridden since seems to be able to incorporate this feature.

Ever since I put a couple extra LED's pointing at my face up high on the windshield, I rarely have a problem like this anymore.

Ace, please show us what you did. I would just like a beeper that goes off after a 10 or 15 second delay.

Rick,
I'm a long way from my S10, so this is info from documentation on hand. You don't mention the year of your bike, but I doubt that matters.

I haven't attempted this mod. In fact, I have not purchased the device (yet). Instead, I had a look at their "Installation Instructions" - a link at the bottom of their web pages, conveniently labelled "Installation".

What I gleaned from that:
1. there is a small piece of foam that must be inserted inside the switch housing. This looks to me to be a method of preventing the switch from locking in either left or right turn position (turns the switch into a "momentary contact" type). Note: this is an educated guess. Note 2: this also means that the switch housing must be opened up.

2. the install instructions show that you must cut and splice into the stock wiring harness at the terminal blocks using crimp-connectors. To do a neat job of this will require far more skill than the average motorcyclist usually demonstrates. To do this properly would require metal-only crimp splices, those with no plastic housing, (or a soldering job) staggered to prevent a huge lump, each splice covered with (waterproof) shrink wrap.

I am also adamantly opposed to the type of splice that they show for the power leads. Those splices may work on your garden trailer but not on your motorcycle. For a far better solution, see: https://www.motorcycleinnovations.ca/category_s/2240.htm -REF: Posi-Tap Connectors. Note: I recommend the Posi-Lock connectors as an alternative to the bullet connectors shown, but they will still make a pretty big lump.

As you have mentioned the terminator blocks, it appears you've already found the best location.

The video does a much better job of showing the process than their written instructions. On my computer, the colors are not very good making it difficult to determine the true color of the Ch (chocolate) and Dg (dark green) wires - but it is obvious which is the BrW wire.

Information that I have indicates that the power feed comes from the turn signal/hazard relay (69) and the wire is Br/W (Brown/White). It feeds the turn signal switch (77) and the hazard switch (76). From the turn signal switch, the right hand signals (F-80)(R-82) are fed by Dg (dark green) wires and the left hand signals (F-81)(R-83) are fed by Ch (chocolate) wires. In the location where you will be doing the splices there is only one of each wire. The split between front and rear obviously occuring inside the harness.

Please check this information with a probe or a VOM at the terminal blocks before cutting any wire. Note that you can also determine the correct wire colors by opening up the lighting housings and checking the color of the wire that feeds the bulb.

I hope this helps. Your Mileage May Vary (YMMV).

Is the above the only option for self canceling turn signals? At this point it’s my only complaint with the bike. Unbelievable Yamaha can’t do this. Archaic to say the least.

Take both cover off right side. ( If you were sitting on the bike brake side). You will see a hooded rubber plastic boot. Your wires should be in there. From what I have read start by taking appart the turn signal switch, verify colors and in sert foam pieces. Then move on to the upper cover with the boot.

I ordered what I need to make a harness. Plug and play. Did my rigid light that way with aux plug. Then as always I took the long way around the barn, and put a Eastern Beaver fuse block in. Which should serve as my switched power source without splicing. Now just need to find the time to put self canceling turn signals in. They are collecting dust. Let us know how you fair.

Another Fourm member completed this successfully harness and all. He inspired me. :)

What is the purpose of self canceling turn signals? I have never had a bike or car with them. I had a rental car last year that made an audible beep when they were left on too long. It was very annoying to have them ding when I did not even make my turn/lane change yet. OTOH if it knows when you make the lane change or turn then shuts off, that would be cool. I'm pretty sure they are on some kind of timer that has no way of knowing if you completed your lane change or turn yet.

I would consider self canceling signals a major safety hazard. I can't remember the last time I forgot to shut off my signals on this bike. The indicators on dash are constantly flashing. So your peripheral vision is reminding you they are on.

IMHO we need to use the SMITH System more. It's free and is much more effective.

Aim high in the steering
Get the big picture
Keep your eyes moving ( this is you self canceling signal built in)
Make sure they see you
Leave yourself an out

I have had them on my Harley's. They are nice. There is always one guy in the group who leaves a turn signal on. It can stay on for hours. That in it self is a safety hazard. With that said any safety devise has their risks. Air bags can burn or break bones. Seat belts can keep you trapped in a burning car. In college there was a crash, with three People in the car. The lone survivor did not have a seat belt on and was lying down in the back seat. They rear ended a 18 wheeler. Took the diver and passengers heads off. Ever try to duck with a seat belt on. It stops you. Safety devises do save lives on a whole. But they are far from perfect. They just increase the odds in your favor,

There will always be folks that don’t want self canceling turn signals. All you have to do is watch motorcycles driving around with a turn signal turned on that they simply forgot to turn off and it becomes pretty obvious that self canceling turn signals is a very nice feature that should have been standard equipment on the Tenere . All the motorcycles I’ve owned since about 1981 came equipped with self canceling turn signals.......until I bought my first Tenere. If the Tenere was the only bike I owned the no self canceling turn signals issue probably would become acceptable but since all my other bikes for the past 700,000+ miles were equipped with self canceling turn signals not having them on the Tenere just seems like bs.
If the Smart Turn system was plug and play I very likely would buy it.

What kind of cars have you owned that didn’t come with self canceling turn signals ? I learned to drive in a 1953 Chevrolet pickup that didn’t have self canceling turn signals.

So the STS, does have a timer function but it primarily works off of an internal multi axis inertia / gyro unit that actually senses when you have completed your turn or even a lane change. Installed one about a year ago I guess, maybe less. The installation is a bit intimidating and the wiring colors in their instructions for Yamaha are incorrect, at least for the super Ténéré. As mentioned above I recommend opening the switch first to verify the correct wire colors. You have to open it up anyway to insert the little pads that stop the switch latching.

My experience with this system is that it detects and cancels actual turns with 100% accuracy ever time, just as the bike comes back to vertical - bang off goes the signal. For lane changes it’s only about 50 - 60% accurate unless you’re on a flat straight stretch. Making a slightly exaggerated swerve as you change lanes seems to help but not always. If you kind of just make a drifting lane change without really leaning the bike at all, it won’t sense that and won’t cancel. That’s where the timer function comes in, it’ll time out after 20-25 seconds if you forget to cancel it yourself.

Using the system takes a little retraining because to cancel the signal manually, you have to push the switch again in the same direction instead of pushing it straight in.

If I were to do it again I think I’d buy the extra connectors and build them up to make it a plug n play installation. Overall I’m pretty pleased with the system, it’s actually pretty ingenious.

I mean self cancelling as in making lane changes. The ones on a timer....

Right on!! Now that's a super cool feature. I find that sometimes it takes forever to get over when making lane changes in traffic. Hence why the timer does not seem safe to me. While I'm pretty good at remembering to shut mine off, of course there are times that we all forget to do something so simple.
