Some of the 2018 KTM 85 SX engines are suffering an internal issue caused by the weak idler gear retainer installed in them. The retainer is very thin and eventually bends, potentially leaving the idler gear able to come loose, and can even break the engine case. One of the main causes is kicking the Engine over far harder than is needed.
Lynk’s Racing has devleoped a superior quality fix to be used BEFORE the engine case breaks. The kit will include a new retainer bushing, a longer bolt for sturdiness, and a new locking tab washer for the clutch hub nut.
