Got a weird low-speed vibration through the bars on the way back from a ride yesterday. Thought I might have lost a wheel weight, but it was worst at a crawl when slowing down for stops. I could feel pulsing in the brake lever just resting my fingers on it. Pulled the wheel off and sure enough the bearings are worn. In all my years, I've never had a wheel bearing go bad on me, but this is the first bike I've owned with over 115,000 kms.
KTM's parts fiche shows them as 6906 DDU2CG23S6NM, Google says made by NSK, but unavailable anywhere. ADVRider says the G23 suppsedly means slightly looser tolerance for the axle to slide in/out without tools, but even if BS, the KTM's are only $10 more than the generic NSK 6906 DDU or DDUCM on Amazon, and I won't have to wonder in the back of my mind whether they're fake.
