Yeah, not sure comparing an Indian chieftain and a rocket3 is fair. They’re almost different classes of motorcycle entirely. The rocket is essentially an engine with a bike attached to it that triumph designed some amenities for to accommodate some light touring. I too had the 20l bags replaced under warranty. Locks got jammed from road grime while touring in Maine. The new 25l bags IMO are adequate if you have realistic expectations about the bike. If you need more storage, a waterproof triumph tiger bag on the back rack does the trick, and essentially matches. Put on a couple thousand miles with this setup, only issue was the mentioned lock on the 20l saddlebags which triumph replaced under their 2 year accessory warranty with the newer models, no questions asked
