I figured my mileage divided by 50 mph per 1 hr of riding. I figured 50 mph is a good average for my riding. (mostly street). Based on my mileage that would be approximately 846 hrs. I usually changed my oil based on the average car mileage which I figured to be about 60 hrs per oil change, about 3000 miles. I know off road is much harsher on the bikes. Is anyone using an hour meter? What are your off road maintenance schedules based on hrs? I may begin more trail riding this next year since I ride my Radian for street mostly now. I am looking to add an hour meter to my bike. Any suggestions?
