Great bearings
I ordered the bearings from VBX for a 78 Yamaha YZ400 Rear wheel, the bearings fit perfectly and work great.... [...]
work on a scooter engine good
After dealing with a large number of bearing failures in Chinese Scooters we decided to try these. They have held up better than expected and the Nachi Japanese bearings are a good replacement for any bearing in a Chinese Scooter or Moped.
I picked these up to replace my stock Husqvarna 394xp chainsaws crank case bearings. They were spot on with the stock bearings but the 2 bearings were cheaper then 1 bearing. I am considering purchasing another set just to have on hand. I have bookmarked vxb and plan to return for any other bearings I may need.
