415 Chain is more heavy duty and stronger than standard bicycle chain. Not to be confused with 415-H chain which is not recommended for our 2 stroke bicycle engines. 415H will bottom out in the 10T drive sprockets found on China made bike engines including ours thus making the chain to not track evenly and will cause it to jump off the sprocket.
Ship wt. is 3 lbs. but this Shopify website cart will bill you $10 for 5 lbs. so order more stuff not to exceed 5 lbs and get a free addition parts ride. Got it?
