As a result of its cowboy-esque lack of convention, the law was struck down, and in its place, Montana's state legislature set the speed limit at 75 mph. In one last push toward hope, Montana increased its highway speed limit to 80 mph in 2015. It ain't much, but it's something.
Portions of the Idaho, Montana, Nevada, Oklahoma, South Dakota, Texas, Utah, and Wyoming road networks have 80 mph (129 km/h) posted limits. The highest posted speed limit in the country is 85 mph (137 km/h) and can be found only on Texas State Highway 130.
What's the top speed of a 50cc moped? Most 50cc scooters come with a restricted engine, which limits the bike to a top speed of 30mph (48kph). However, a 50cc scooter can go at speeds of up to 60mph (96kph), while most will comfortably reach 40mph (65kph).
1. KTM 450 SX-F (198 km/h – 123 mph) – 449cc. The KTM 450 SX-F is best known for propelling Ryan Dungey to Motocross championship. Its powerful 449cc engine is only 237 pounds, but it can power top speeds of 123 mph.
Cars were not expected to maintain sustained highway speeds hour after hour. The 1960 Falcon never came with an overdrive gear in automatic or manual. You were expected to amble up to 50 mph and stay right there.
You can get the rear shock rebuilt (reshimmed) to lower the sx65. However, I would just let him ride it stock. He will adapt.

For a 10-year-old, the dirt bikes that I recommend for an average kid just wanting to have fun and not race seriously is either the Honda CRF110F, the Yamaha TT-R110E, or the Kawasaki KLX110. These three models are a good size for a 10-year-old and are priced reasonably.
The KTM 65 SX features cutting-edge 2-stroke technology and an easy-to-shift 6-speed transmission with a hydraulic clutch. Benefitting from a reworked ignition curve, the cylinder, with its pressure-controlled exhaust valve, continues to provide class-leading power and plenty of torque.
The
YZ65 is track-focused with its adjustable suspension, bump-absorbing steel frame, grippy Maxxis Maxxcross SI tires, 65cc powerplant, manual clutch, and six-speed transmission.
