Turn System is a great add Turn System is a great add, solid 5 stars. Brake module works great on my CBR 600 but does not work very reliably on my GS1200, they refunded me for the one on the GS. My friend also has one on his Z1000 and it works great, I've been riding behind him to help him test. Overall very good, but customer service is a bit slow to respond.

SERIOUSLY PUTS YOUR LIFE AT RISK - COWBOYS! Does not work! Advertised as a lifesaving product but as it flashes all the time when not braking it's actually a life-threatening product. Was told to return it to get a refund. After sending it to the address I was told, after weeks it was returned back to me in Australia marked as rejected by Slovenia customs due to ST2 not providing some detail to their customs department. Battling with PayPal now to get a refund. AVOID LIKE THE PLAGUE!

THIS DOES NOT WORK AS DESCRIBED THIS DOES NOT WORK AS DESCRIBED, FLASHES brake light when accelerating =, going over road bumps etc, no good. I had 2nd unit sent to me but it was the same, had to claim through paypal as they will not reply to my emails after 2nd module ws posted, AVOID ITS GARBAGE

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. Here is my install www.r1-forum(dot)com /threads/st2-systems-com-brake-and-turn-signal-modules-warning-this-product-sucks.645340/

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….
