I wanted to drop a quick review of this product, their are product reviews on the web if you search.
I felt compelled to post a review as this product met and exceeded my expectation. Let me begin by asking we not let the thread deteriorate into a
-y'll don't need self cancelers cause you have a button
-if you can't remember to turn it off you should no be riding
-198x bike had them why don't they put them on now
I know there are other system for a few dollars less, I researched them. Various setups fro 99 to 125 bucks. This was not exactly cheap at about 175 with shipping or whatever.
OK, that said I did not like the idea of time based turn off. Not useful for quick lane changes (stays on too long and would confuse the other drivers). Time based does not work well for a long cycle light as it would turn off too soon. The only thing I see time based systems useful for is if you forget to turn it off it will do so for you, eventually or too soon. Yes some of those setups work on other algorithms but don't consistently turn then off as the rider would do so.
The ST2 system turns off based on some pretty smart firmware built into the unit. I can only suspect exactly how it was programmed by using accelorameters, decel sensors fore and aft and lean angles etc. For instance it knows if you slow down, have a slight lean then speed up it turns off. If it senses lean with only slight changes in speed it interprets this as a lane change.
Let me just say once I got this installed I was using my signal for everything I could and it simply would not malfunction or be faked out. I could signal L or R leaving the driveway and it turned off once turn was completed plus a few seconds. Slow speed lane changes, high speed lane changes, lane changes slowing and or accelerating, lane changes slowing speeding then changing. L or R turns with decel followed by accel then stop and go. Turning it on just a second before turning and so on. I just could not make it confuse itself. It just flat friggin works like a well trained operator would turn the signal off. Only complaint is if you signal and fail to do a turn it will continue to flash, I have not found a way to cancel an errant signal other than to do a slight lane change. When I say lane change it does not have to be a full lane change, simply veering inside your own lane will turn signal off, It will time out and I THINK it times out sooner if there is no change in velocity but can't confirm this just yet.
I am totally jazzed about this product, I use my signal for everything now, lane changes in country when no one is around. In town and on highway for lane changes so on. It is just so easy, push the indicator button and know full well it will be cancelled when the maneuver is completed.
From a safety perspective I know we should cancel our own signal but-
Forget ONE time and have someone turn if front of you or otherwise misinterpret your intention and you are in a reactionary emergency situation.
In town or when corrections to your intended route turning off signal is an extra step to remember and is a distraction from focusing on riding.
Removing or changing my hand position in traffic to reach the button is distracting to me, I cover the clutch and brake levers at all times, dirt bike riding experience there. On a side note I have modded my levers so I can rotate down the levers as well as the turn signal assy switch by grinding off the tabs and knobs. Makes easier to use thumb and fingers positioning is improved. I am very sensitive to lever position as a woods racer on a small bore bike racing in against 450's and such. You have to use the clutch and brakes simultaneous to keep the engine singing.
I don't often post my opinions on products but felt others may want to look into this product. Installation was pretty easy, just tapped into the wire harness from the switch. I did use the supplied bullet connectors but would recommend simply cutting and splicing as it makes a much smaller bundle to conceal. Mounting the actual device ( it requires somewhat horizontal mount for sensors to work) was a piece of cake. There is some cast bracket the holds the front tupperware stuff that is machined AL with a cutout same width as box, I just velcro mounted it there. Easy.
