I was riding yesterday and my hub just snaped. All of my sproket bolts were good and snug. I run a o-ring chain, but had plenty of slack. I was riding down a straightaway when it broke, luckly, because it locked the rear wheel up and broke my sproket in half. I understand It must have been cracked before that, but just wondering if anyone else has had the same problem with there hub. I contacted Yamaha, and they said that they have had no problems with this in the past. I makes me wonder why they put the same hub on a 125 as they do on a 426.
