I have a 2018 Rush, and I ordered a service manual for it that I got yesterday. I also have a 2016 Rush, both are 600cc. Can anyone tell me what the difference is between the two? They make a 15-17 service manual, and an 18 service manual, and I have looked through most pages, and they both seem to be identical? Also, did they quit putting part numbers in these manuals now?
