Just an FYI, the prefix numbers and letters ( before the base or common brg number) tell a lot of info as well as the suffix ( numbers and letters after the base or common brg number). Just a for example usually the crank roller brgs are of a closer tolerance than a typical brg with the same base ( middle) number. A brg of the same size and same base number could be a sealed, shielded, or open type, could even have a snap ring groove on the outer diameter. If all else fails take the brg to the parts / brg house if in doubt. Personally I dislike proprietary brgs. On production machinery or equipment that I was responsible for, I’d machine out the housings to put in common brgs ( where possible). It takes a lot of time and study, but worth it in the long run. Not saying this one particular brg used in the KLR engine with a machined shoulder should would be worth the time to figure a way around it. What I am saying is be aware that the brgs you buy from on line or a parts or brg house have the same identical numbers.
