I'm getting different messages from people on why I should/shouldn't put a Regina ORN6 on my 06 YZ450F as Grayracer had recommended. I don't race it, just ride the varied terrain in Ocotillo on the bike, but want my stock sprockets to last and not have to adjust it every time I ride, as it seems I will have to do with the stock chain. What are the pros and cons of the O-ringer for my riding situation, and should I just stick to a non-O-ringer? I'm willing to pay the extra dough if it's worth it for longevity and strength, but not as much as an X-ring. Somewhere between $40 and $75 is the range I'd like to spend.
