I have seen these bearings advertised with the blue seals. Are they worth the extra cash? What makes them so special?

Haven't seen the "blue seal" bearings, but NGK makes quality bearings. I personally havent had any problems using their standard sealed bearings though.

You don't have to believe everything you think!

I have heard of the blue sealed bearings but I can't remember what was so special about them. But there was something...

Just fyi, I ran NTN bearings last year. Cost just a little more but NO noticeble difference. None of them have worn out yet though. I don't race and i only get about 500 miles per year. this year (on other sleds) I'm switching back to the basic bearings.

Two most popular bearings are:
1. 6205RS
2. 6004RS

Cheers.

NGK bearings are the cheapest bearings you can buy. They are pure junk ! NTN are above and beyond NGK. Brands like Yamaha use NGK in their ATVs from factory, nothing but junk.
