Must have item! Once you guys had this in stock, Will had to have it! Love it dudes!

Advantages: Nice deep roar now! Makes enough noise that you know this didnt come from the factory! Picked up a bit of speed also. Bart has made this easy to follow to install (really not needed)

Disadvantages: I haven't found one!

Good quality light. Everything is as described, to add to it installing the light was a breeze by following the TST video instructions.

I have a 2003 Yamaha YZF600r that I upgraded with LED headlight, rearview mirror, flush-mount, and tail lights. Although my bike isn't listed for this, it replaces the same part (4MY-83350-01-00) as other bikes that are listed (this part is VERY common... apparently).

By far the simplest solution to my hyper flashing issue. The other option involves trying to stuff a bunch of resistors in impossible spaces and mounting them in ventilated non-plastic areas (bleh!).

Advantages: Took 21 seconds to install and IT WORKS!

Disadvantages: Be careful when removing the housing to adjust the flasher timing. The board that the pins are connected to is not attached to the red piece as the picture(s) might suggest.

Bought this along with the TST 2 pin flasher relay and the Elite 1 fender eliminator. This is a must have to make the Grom sleek looking! Thanks Bart for your install video.

Advantages: Sleek, just looks much much better.

Disadvantages: None!

Great product...Exactly as described and easy to install.

Advantages: Video Install Awesome!

Go ahead and remove windshield, makes things much easier!

Disadvantages: N/A

Great product, easy installation. YouTube videos for installation process are really helpful.

First off I wanna begin by saying TST industries has some of the best customer service I've ever dealt with! Fast responses to my questions, and fast shipping! Also got a 10% military discount which was an added bonus.

Now on the taillight, amazing product! This is my first purchase from tst industries, and I was very pleased with their build quality on this piece. It was super easy plug and play installation and I had no fitment issues whatsoever. The tail light really complements the overall design of the fz-09 with its sharp and sleek edges. Also the led's are far brighter than stock , and the unique oval led pattern makes it very easy to see the turn signals. Best bang of the buck tailight for the Fz-09 on the market hands down!

Might I mention first 20 gets a free relay with the purchase ! So if you're looking for an aftermarket tailight that upgrades the design and functionality of the stock one, for under 80$ , look no further!







Advantages: Built in turn signals
Brighter And more visible led's
Form fitting design
Plug and play


Disadvantages: Have not found any yet

Awesome product with good quality. Everything as described.

Advantages: Fresh look of the product. Plus the TST video helped to put it on. Very useful video.

Great product, plug and play harness makes it extremely easy to install. I bought the smoked set, looks great on my black CBR 600RR

Nice plug and play solution for hyperflash - no brainer.

Advantages: No soldering or splicing wires!

Disadvantages: ***Bought for 2017 CRF250L***
I'm not sure if this is peculiar to EU/UK models, but there is a water-tight rubber boot which the stock relay fits into. This replacement is much thinner and thus the boot does not fit around it and would not prevent water ingress. I ended up wrapping many layers of electrical tape to approximate the diameter of the stock relay so that the boot would be a better fit.

Now that I write I do notice the "E" model has the correct shape, but has 4 pins, which is 1 too many for my bike...
