I ran the stock chain for 5000 miles and then replaced with an EK o-ring chain. Didn’t change the 13 countersprocket or the 45 rear. Ran that EK chain 10000 miles. They are $45 USD. Both the 13 and 45 still look great so I put another chain on it and will replace the whole thing before my Alaska trip. And I do both big freeway runs and tough off-road
