Yup. I have the VM520 on my M966 with 100 hp, too. On paper, the VM520 and ERV2 are pretty close. When you quiz their engineers, they say that the ERV2 is a race chain and not really intended for street use. Basically, the ERV2 is an "all out" chain. In my opinion, the VM is just fine. It's a little heavier than the ERV2, which also equates to slightly more longevity. Well cared for, 15,000 miles isn't a problem on them.
