415 Chain is more heavy duty and stronger than standard bicycle 1/2"x3/8 chain. It is the correct size for our SkyHawk engines.
BEWARE: Do not confused 415 with 415-H chain! 415-H will not fit our SKYHAWK 2 stroke bicycle engine 10T drive sprocket.
415-H will bottom out in the 10T drive sprocket like found on China made bike engines including ours thus making the chain 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 ride for the additional parts. Catch the vision?
