Went to dealer yesterday to speak to them about the first 500 mile check. From my understanding... the oil should be changed in the Ryker after the first 500 miles. Looking for info from Ryker owners as to what other routine maintenance is done at that time. I was told by a salesperson that if I change the oil at home and dont bring it in to the shop that my warranty might be void if an issue arises. I purchased an extended warranty as well. My Ryker has been doing great- but anxious to hear from other owners out there.
