I'm sure the strength is much more than needed. I've had a couple L brackets from Lowe's for a license plate bracket on my 14 for 7 years. Very cheap, plenty strong and very lightweight. Heck, I made a similar thing out of aluminum for my busa. It works fine and weighs about zip. Unless you have plates made of cast iron, you don't need much to hold it on.
Ditto, agree with Rook, I bought the same L brackets at Home Depot for my '06 ZX-14..... but I went deluxe and bought the ones with the brushed nickel finish for about $2. The pitch on the under tail bolt holes was identical to the spacing on the license plate bolts, almost like KHI planned it that way....hmm. LED license plate light was about $10, stuffs been on there almost 11 years now and is holding up great. Lightest, cheapest and easiest fender eliminator ever.
I don't get it with these aftermarket license plate holders, the plate weighs about 4 ounces but the brackets they use look like something made by Chicago Bridge and Iron....totally unnecessary. My Competition Werkes Tail tidy for my '16 ZX-10R holds the license plate and two LED turn signals but is made from aircraft grade stainless steel, .100" thick. The bracket weighs over 1 lb and supports only a few ounces....ridiculous!
If the entire bike was this poorly engineered, it would weigh as much as an Abrahms M1 battle tank and have the performance of a Winnebago motor home.
