The newer (2018+) models have a Secondary Air Intake (SAI) that is supposed to reduce emissions, a by-product is that it produces "intake roar", which is what you hear under acceleration, this is further enhanced by the redesigned exhaust silencer, which produces a more pleasing sound than the old sewing machine whine.

As Paul, if you don't like it then earplugs is probably the easiest way to reduce the noise, btw it goes quieter cruising at 100mph, most of the noise is only produced under acceleration  :001:

"More pleasing". Too loud IMO. I miss my 1200 sound, this is too high for long trips.

My 2018 XRT feels fine at 70mph, no intrusive noise, vibes or sensation of it revving higher than it actually is.

Ah Dilbert my man.....
How do you know that the noise gets quieter when cruising at 100mph; surely you're not allowed to travel at those break-neck speeds.
Just saying.....

For those who can't remember which way round things are, here's my little poem:

More teeth at the front
Or fewer at the rear
Makes your bike go faster
For same revs and same gear

re ^^^: May also (under certain conditions / all things being equal) subject the engine to more load and may tend to increase combustion temperatures.
May also (in concert w/previous statement) require larger throttle openings to maintain a similar speed thus tending to inhibit any (desired?) fuel mileage improvement.
On a positive note: more teeth on the front sprocket tends to be kind-er on the chain (less wear & tear).

16 tooth front sprocket gives sharper acceleration, but more revs, 17 tooth front sprocket is optimal size, 18 tooth would be kinder on the chain (turns through a larger radius), 19 tooth would (probably) take lumps out of the casings  :008:

Mmmhh  :084: 16 doesn't give sharper acceleration it is stock size, 15 gives faster acceleration but if you're concerned of the sharp radius, just go to 53 on the rear instead of 50, almost same ratio !

I'm not worried about anything, works fine for me and while 16t might be "stock" on the newer models it's not the 17t industry norm  :015:

Kinda wish the newer Tiger had kept the longer 1st gear, like my 2013 Striple R and the older Tiger. I just found it far more practical especially as I do a lot of town riding. Presumably they both had 17t front sprockets?

Weird because all my research on Tigers led to only 16/50 on models through the years, none had 17/50, your Striple has a 16/47 btw which is akin to having 17/50.

Again maybe it's me, but the smooth triple is fine with 16/50, coming from a Honda AT with 16/42 which first gear was really a pain in traffic, I have absolutely no issue it's 19% less arm ripping  :007:.
