This purchase has changed my life. Before I had a rusty chain and worn sprockets. i put on new sprockets (see other review) and this new chain. Well what can I say? In all honesty, the impact to me, my friends, my family and even my dog has truly transcended all reasonable boundaries of any and all possible expectations. My 1986 z50 pit bike has more power, corners better, gets better starts and I think it might even be able to pull the big double on the pro track if I pin it, compress really hard on the face of the jump and then just ghost ride it! THANK YOU!!! In all honesty - great chain for the price and application - fit great, came with master link and came in a professionally printed box.
