I have a 2009 Harley Road King with the six speed tranny. First and fifth gears are straight cut and whine a bit. Amsoil V-Twin transmission fluid makes both much quieter and when I drain there is no metal on my drain plug magnet. It has reduced transmission wear to almost zero.

My Harley was shifting hard and occasionally wouldn’t go into gear. I changed from the crappy HD tranny fluid to this and it shifts very smoothly now. I’ll never use Harley Davidson oil again!
I read a lot about people saying this product makes "finding neutral easier" or "eliminates the clunk shifting into first gear on a Harley". While finding neutral may be a tad easier, it certainly does not do much for the clunk shifting into first gear. I was skeptical about those claims and my experience has taught me those claims were bogus.
