Is balancing necessary?

I recently personally changed my tires for the first time on my brutale. I removed the previously used wheel weights, the last dealer just added more weights without removing the previously added weights *lazy shits*.

I forgot to align the yellow dot with the valve on the rear, about 90 off, and did on the front. Filled them up, set the beads and done. I don't own a balancing kit, so I got a price for $10 per loose tire (seemed fair), but with how quick removal is and my own impatience I decided to install and test them out.

After about 150km of highway decent turns at a good range of speeds and steady riding, I could not feel any balance vibrations and it seemed like there was less vibration than with my last 2 sets of Q3s, I went to S21s this time, which leads me to this question: Is it necessary to balance undamaged motorcycle wheels?

I always thought so, but after my last change and ride without balancing, I'm skeptical.

Just my opinion, but:

Yes, just to cover the 1% of tyres that slip through the manufacturing process that are less than perfect, and to cover for the non alignment of the paint dot.
Yes, at least to account for the metal valve stem.

I get mine done on a dynamic balancer. The last 3 sets of tyres required no change to the existing weight attached.

Modern tire manufacture makes the high end brands have pretty consistent weight distribution. It's usually the wheels that you balance, as revhead1957 noted.

Now, if you buy Shinko or similar low end tires all bets are off.

But all components being high end, you may not really notice much vibration or wheel hop if the balance is just a tiny bit off.

I used to be I just dream about it.
