Bearing Info for the Vmax 4

Bearing Info-- Wanted to put together a reference sheet for Bearings. Everyone’s personal budget will dictate the bearings they use--- After doing some research this past summer I decided to replace my skid bearings w/ less expensive Chinese Bearings, and replace my chain case and spedo bearings w/ higher quality KOYO Bearings. I made this decision after meeting in person with a manager at Bearing Headquarters. He explained to me that there is a HUGE difference in cheap (Chinese) bearings and higher quality (Japanese or German) Bearings. Yamaha NOS bearings are KOYO (Japanese), and I was able to get replacement KOYO t bearing headquarters for 50% of NOS from Yamaha.

As per the guidance from Bearing Headquarters, there is a significant difference in quality between cheap (often Japanese) bearings and higher quality (Chinese or German) bearings. For critical components like the chain case and speedometer, investing in high-quality bearings like TBS is recommended. While it might be tempting to go for the least expensive options, remember that higher quality Needle bearings tend to last longer and perform better, potentially saving money and effort in the long run.
