It appears that KTM is trying to quietly fix a problem with some of its KTM 390 Duke bikes without actually submitting a formal recall. They are instead calling it TI, or technical information.
Bikes built before March of this year may have their front sprocket misaligned, and as a result, the chain may come off the teeth. The problem was detected by KTM, and bikes built since March have proper front sprockets installed instead of the faulty ones.
KTM has not issued a formal recall because that is only done for "safety related issues," though I'm not exactly sure how the chain coming off is not a safety issue. Instead dealers are quietly fixing the problem during routine service operations.
KTm doesn't want to tell you, but luckily I am here to relay the news to you guys. If your 390 Duke was built before March, maybe you should think about taking it in to get things checked out.
