Very easy . I weigh 175 and my 80 cc gets up to 45 mph with a 36 tooth sprocket and niome flex tail pipe.

I have big bones, I’m at 215lbs and my 66cc cruises at 35 fairly easy, hills will slow you some.

I have a 80cc on my 26" beach cruiser and I weight in at 196 pounds. I have been clocked by radar at 42 mph in a 35 zone.

Use a 32 motor sprocket- you'll fly.

Everyone wants to go fast, just remember most bicycles (wheels, tires, bearings and brakes) are not designed or built for speed. Adding the extra weight of the engine and fuel, plus some of the frame modifications some have done to fit their engines also adds to the problems. Just my 2cents for what it’s worth.

What's more important than going fast is Stopping. If you're wanting to go really fast; then you need disc brakes. You need a frame and wheels capable of handling high speeds.
Other factors are:
Total weight
Terrain
Rider frame fit
Aerodynamics
Engine performance.
What all this means is if you're tall and thin, a frame can fit an engine and still be the correct fit for your body. A short light person using a frame that fits their body may not have enough room to fit an engine in it. Frame size has nothing to do with wheel size. Frame size is also important when it comes to aerodynamics. You'll be able to tripod further down towards the handlebars in order to cut down on wind resistance.
If you're a flat lander, use a 32t rear sprocket; these are the rpm your 2 stroke engine will have to do according to wheel size to reach 45 mph. This is where engine mods to improve performance will come in.
24" >> 8269
26" >> 7634 rpm
27.5" >> 7217 rpm
29" >> 6844 rpm
