Hello Everyone! I'm new to the forum! I just purchased a pristine, 2020 Ryker Rally with only 1100 miles on it. I'm reading the maintenance schedule and it states at 24 months or 12000 miles the Final drive oil and gear box oil should be changed. Is this service really necessary since with only 1K miles? If so, has anyone tried doing these fluid changes on their own? Any how to tips?
