My girlfriends Agility 125 has over 11,500 kilometers on it and never had a valve adjustment. It runs great. I bought my A 125 with 6500 kilometers on it, don't know if it had a valve adjustment or not and it runs great too. Do some more checking on here and I think you will find most people say they don't need one. You might need to have it checked to keep the warranty valid, but I think the dealer just wants your money. Either way you will enjoy you Agility for many, many miles/kilometers.
