Excellent product, late delivery
The product was fine. Love it. Amazon dropped the ball. It was supposed to be here on a Sunday, Amazon delivered it Wednesday. My bike was down waiting on it. I called them twice, promised it would be here Monday, no show. Called Tuesday, same thing, no show on Tuesday. Late Wednesday it came. Got my bike going Thanksgiving day.

good value
got this for my 2021 Road Glide Special and so far so good. Red Line has been around a long time & in the racing circle too & i trust this product as much as i trust Harley oil , . Will buy again unless a better product is available at the time i change my primary oil again.

Never skimp on lubricants
Redline synthetic is probably way overkill for my Harleys here in the Pacific Northwest. It's waaaay more expensive than most anything else out there but I've always had good results using it. My chain adjustment shoes still look pristine so that's certainly worth paying an extra $10 for this stuff. I change it out every couple of years and way before the recommended 10k mile interval. But for me, the high quality is worth paying extra even though I'd probably be fine just using 20W-50 motor oil in the chaincase.
