Charged Advice

It's a well known motocross racing "secret" that an o-ring chain has far more friction in it and robs you of power, you'll notice a nice little power increase with this chain, perhaps even some range.

If you upgrade to a larger sprocket and need a longer chain or have a wide tire and you are struggling with chain clearance, here is a simple solution, install a non-o-ring chain which will provide about 1mm of extra clearance between the tire and chain.  Be sure to use chain lube and keep your chain clean, without o-rings this is very important.
