stock around 60mph, without restrictions close to 70, anything above that would need an upgrade in the final drive.
A 43 cc scooter will usually top out at around 30-35 mph.
12 mph
In general, a 600 cc scooter will go well over 100 mph. 125 mph is easily possible, given the right conditions. It does vary by model and manufacturer, but 120 is about average for a 600 cc scooter.
The 250 cc motor scooter is commonly the largest engine size scooter. The 250 cc scooter has a top speed of about 75 miles per hour, but usually the engine size will top the speed out at about 60 miles per hour.
Well, that depends on how much you are willing to spend and how fast you want to go. I would recommend the larger Honda scooters, like 150 cc and over. They will cruise at 55 mph and go over 70 mph. Or if you really want speed, get a 400+cc maxi scooter. They are good for 105+ mph. Just go to a motorcycle shop or a scooter store. Vespa makes scooters that will go 80 mph too.
as fast as it can
very fast
A 200 cc scooter will go around 70 -75 mph on average. This is plenty of speed for cities and 55 mph roads, but nothing more. They are not great for the free way, even though it is legal. I would look into a 400 cc scooter, like the Yamaha majesty for the free way. These will go 80 mph all day long into the wind, and approach 106 mph.
A 385 cc scooter will be very fast. They will top out at around 105 mph and will cruise at 80 mph all day long into the wind. They will be a great highway touring scooter as well as perfect for those long commutes or that trip to the store with over 15 gallons of under seat storage!
as fast as you want it too go
The grass has more friction than the concrete, so the scooter doesn't go as fast
