Harley is for just rides in perfect weather! But they are nice ! You can enjoy the ZL1 all the time and take it to drag strips and road courses ! Take everyone with you and can let the sunroof back! But I don't think it's fair to compare the hardly to the 580hp ZL1. Or any 5th Gen! Just go buy the Harley , since it is the same as a ZL1! Too you!
