Is this oil ok for bikes with catalytic converters?

I use this oil/grade in my 2017 Yamaha FZ09 and it has a catalytic converter, I've had it professionally services and they have found no problems.

Why is this a different part # than buying directly from Motul on Amazon with their part # listed as 836141?

104121 is the Motul SKU. Amazon might have listed their own part number.

How would this perform in an 82 v45 magna?

Google says its 4 quarts of 10w40 for your bike, Personally I have used nothing but 300v in my 2018 gsx250R changed every 3000 miles with zero issues or glitter in the pan after oil change even running it 2212 miles up/down the interstate at 80 mph at 9k rpms when the top speed of my bike was 88 mph. About to do it all again in a few days. Bought the bike with 728 miles on it and now am at 28,4xx miles. It 100 percent has worked for me. Hope this answers your question. Have an awesome day.

Best oil on the market for sport or sport touring...Period

Does what it is supposed to. Protects engine, shifting and clutching are spot on, and i have a quick shifter, so the clutch is rarely used. It is pricy so buy it by the gallon.
