ST-2 Brake Module Installation
« on: September 07, 2023, 05:48:53 AM »
Received this item yesterday. Plan to install it today. Interesting idea, Made in Slovenia! The clips supplied are nice enough I plan to use them. They are sealed with gasket material and once clipped on to the wires (ground, power and brake signal) the male spades on the module just plug in. My Canadian spec Honda Varadero has the lights on full time, so easy install?

In theory, any significant deceleration will simply apply the brake light.

I am aware and interested in this as well.

Just finished up. Super easy and tidy installation, despite the Varadero having a lot of “electronics” packed in behind the taillight. Used their connectors and they worked really well. Slipped a small piece of bicycle inner tube over the three connectors and zip tied both ends.

Will take pictures next trip to the shop. I didn’t permanently mount the box (peel and stick Velcro comes on it). The guide suggests you can alter “sensitivity” by adjusting the forward tilt or rake. Playing with the box after completing the wiring confirms it’s a pretty simple inertia switch. It just energizes the brake light on decel. No flashing or added bling. I’m a big fan of KISS, so fine by me. On any of my SOHC cb’s this would be a 10 minute install. Only change would be to add a fused and dedicated power lead, so it would work even if the lights are “OFF”.

I would be slightly more interested in the unit with flashing response upon deceleration.

Frank….. I think they sell those too, some I saw were even “programable”. I bought the plainest (cheapest) version. Went for a ride last night and a friend reported it seemed to flicker or flash when not really required. The only adjustment on this unit is the angle it sits on. All the under seat plastic and framework on the Varadero is raked steeply forward, so will need to shim the nose of the unit up a bit. Pictures later…..

Measured the angle of the control unit using my “Tilt-Box”. It’s sitting at 5.8 degrees, nose down. Added a small 3/16” shim under the nose and raised it to 3 degrees, still a bit nose down. The bike “tail sags” a bit when I’m on it, so will test this angle, next time someone is following.

Just ordered one. Watched a couple of videos and learned that by mounting it upside down, you get the multiple flashing.

That’s interesting. No mention of that in the instructions!

I learned that in this video, at the 6 minute mark.

Went for a good long ride today, with two buddies. Both noted the brake light is still flickering constantly. Obviously, 3 degrees of rake on the  control box (nose down) is still too much. Will make up a 1/2” shim and see if that gets it level. In fairness, that’s what the instructions suggest.

Very cool, sort of a brake switch you don’t need to think about.

Steve….. Exactly. When I downshift through the gears, the Varadero virtually pulls itself to a stop. I need to constantly remind myself to pull the lever and show a light. Hopefully (when I get it set properly) the “box” will remember every time.

This thing may be defective! None of my adjustments are making any difference. This may turn out to be a waste of time and money?

Yes. Very occasionally in places where traffic is heavy and most are on their phones!

Well….. one more mounting attempt (on advice from ST2), but they also sent this. May need another unit!

Okay, please let me know. Maybe it is a faulty unit
Kind regards,

They will replace it if it won't work, so you won't be out your money. If it simply doesn't work for your bike, you return it and money back ..
Not fun, but fair.

David…… it works fine when I tip the control box forward and backwards, but there is a strange “clinking” noise from inside. When I told the tech about the noise is when he suggested it might be faulty….

Might have had a big drop in transit that has caused it to have the issues.

On our 1,060 kilometre ride last weekend, the brake controller flashed on and off when ever it felt like it! Fortunately the lights work normally when I use the pedal or lever, so no problem. Contacted ST2 and they have mailed me a new one.Their tech agreed that mine is “faulty”.

Sorry you had a bad one initially. You can cut open the old one and take a gander at the guts if so inclined. Figure they potted the board, I wonder what is bouncing around inside, clearly something important.
