At the risk of jinxing myself, My black engined 01 has been so good to me. Better than I've been to her thats for sure. I just dropped the oil a couple of days ago, and I'm way too embarrased to say how overdue the oil change was. Much to my surprise and delight, the magnetic sump plugs came up nearly clean. And no debris in the embarrasingly dark motul I dropped out of it. Its got 40thou Kilometers on it, 28k's worth from me in the last 2.5 years. I wail on it every time I ride it, and in summer temps yours will never likely see over there. So either I'm one lucky punter, or theres a bit of paranoia attatched to these engines.
FWIW, there was no 640 "SMC" People just like the stickers.
