Hello all. I have an 03 serk. Do the drive belts have an "age" at which they should be replaced ? Backstory: The guy I bought it from, with 7k mi on it, was a "car guy". He loaded the bike in the trailer with his show cars. He and his wife used it as a "pit bike" at cars shows. It is now 16yrs old, with 10k miles on it. Belt doesn't show signs on negative wear, just old. Do they dry rot ?
A little guidance would be appreciated.

I have an 04 w/ 53k on original belt. You’ll likely get opinions on both sides but I don’t plan to change mine until it breaks. I inspect it very closely at every 5k service and before any trips. It looks like a giant pain to change it (and likely expensive) plus H-D makes a temporary belt kit that’ll get you home.

Never had a drive belt fail unless it got cut by something. I have lost a couple primary belts fail. Everyone of the primaries failed going into second going across an intersection after a couple jack by stripping the teeth off the belt. ;)

The main takeaway here is the importance of inspecting the belt and sprockets for damage, and not just going by age or mileage. The belts, especially the older wider ones, are extremely tough but they can be cut by debris. Make it part of your maintenance program to inspect the belt and sprockets every time you change the fluids. Check the shop manual for descriptions and pictures of acceptable and not acceptable wear and damage.

I do inspect it as part of my regular maintenance. It looks good, but I am going to remove the oil pan for cleaning , due to cam chain tensioner shoe problems. If there is an age issue, wanted to get it taken care of now.
