What a load of rubbish!! What a load of rubbish!!! Fitted to my 2016 triumph street triple and all is does is flash under acceleration and deceleration. Appsolultly useless do not buy from these people I messaged them multiple times and only got one reply asking if it was fitted properly. The answer is yes it is as I am a 25+ years mechanic. This is junk item….

Automatic brake light. Automatic brake light. I had no issues with buying and delivery of the unit. After delivery I regretted my purchase as the design didn't live up to my expectations, and contacted customer support. After a while i got a response with a return address. I payed around 30 euros for return shipping, and shortly after the shipping company send me a email that the address doesn't exist. I have tried calling the official phone number, and left message on the support, but no 4 days later there is still no response from customer support.

I have purchased several products and… I have purchased several products and have had a great experience with the products and service. First was the turn signal module for my KLR 650, which I needed, I would ride for miles before turning them off. Thank goodness it works as it should. Recently I ordered to brake modules. One for my Harley Road king and one for our (Hers) Cam Am F3L Just installed a couple of days and appears to work as stated. Haven't had it out on the road yet. OK, so here is why the best customer service I have had anywhere. I received two Flasher modules instead of the Brake Modules. I emailed about the situation and had a response next day only to find my order was for the flasher modules. My bad. Customer service has sent me a brake module for free! Waiting for delivery now.

Dire customer service and rubbish product Installed on an aprillia RS4, constantly flashing unless unit is near vertical in which case it doesn't flash at all! Contacted st2 systems to which I was told to install it with the wires tilted higher than the rest of the unit which I had already done - waited and tried it in my sfv650 as it should be smoother but still the same, they don't reply to my emails now and are dire aftermarket care. They take your money and go! not happy at all!

The company offers no support The company offers no support, after trolling you for your email address by offering to send you via email the results of your comparability test to see if their product will fit your motorcycle. Once they get your email, you are spammed relentlessly daily regarding “10 more discount codes left” “50% off”, even after you buy, and you can bet they are selling your info. The phone number on their website rings and answers to a dead line. When I emailed Support, I was given a generic email that basically says you are on your own! Documented my install on my Yamaha YZF-R1M of this crap product and company. Countless hours trying to figure this out, with no help from crap-systems.com.
