the owner's manual give a rough break-down on break in period.
Personally, I think the first 1000 miles is all part of break in. I changed the oil and gear lube every 200 miles during that period, and then switched to synthetic oil at 1200 miles.
I'm at 1500 miles now, and she runs like a champ!
Just remember, It's a Super 8 150! It's NOT a highway cruiser!!
If you're wanting to cruise at 60+ mph on the highway, you have the wrong scooter!
Between 35-50 mph is where this scoot's comfort zone is. It will go a little more than that, but it will beg for mercy relatively quick!
But, I'm 230 lbs, so mine has to work a little harder. If you are significantly lighter than me, you may get a little more out of it.
