My R which is also less than 6 months old has rusty spokes on it now but thats about it. I ride all year and in all weathers so I'm not too worried just yet, gonna mention it to the dealer when I next get time to call in and take it from there. There are quite a few people on here that have had this problem and have had good warranty service from their dealers, maybe you got a cranky dealer?
