Do Chinese 150cc scooters do up to 60 MPH on the level ground? I own a 250cc scooter and the Chinese claim it will do 68 MPH on the level ground. There is not a big difference in 60 mph and 68 MPH.
Will a 150cc scooter be able to commute distances of 15 miles at 50 to 55 mph?
Is it better to buy a light weight 150cc scooter verses a heavy scooter? See, I thought about buying a Roketa MC 150T scooter that wieghs 264 lbs gross weight verses a Bali 150 that weighs 298 lbs dry weight. My thoughts on the subject of weight, is the more one has, the slower the scooter will go. I am 6 ft tall and 179 lbs. I am not concerned that I weigh to much.
My wife rode a 49cc scooter, 15 mile on a country highway and seemed to have no problems. It was in a less populated area. But she was only traveling 30 mph . We moved since then and though in a small town, the highways are two lane but more people use them. So need to travel between 50 and 55 MPH.
My 250 scooter is 8 years old and I am going to give it to my son. I would normally just buy another 250 scooter but looking at 150's, I looked at prices, prices if had to replace the engine, well, the 150 made more since. $1000 to replace the 250 engine. Only $290 to replace a 150 engine - that includes carburator with 5 other parts.
Roketa claims the 150T will do 59 MPH and Ice Bear claims 62 MPH. Both use the same engine.

i would assume that the speed claims of 59 and 62 MPH are for level smooth road, WOT, new belt, and no wind. if you plan on doing most of your riding on state roads then you need to stick with a 250. keep in mind this is not an expert opinion, i've never rode a 150, but i do have a 250. my 250 will easily cruise 2 up on state roads.
a 150 would probably do the job, but i would guess it would take some custom tuning to get the speeds you need. rejetting the carb would probably the first place to start.

I have to agree with dollar25, stick with a 250. My 150 is a great little scoot, but it is not designed for, or capable of sustained highway speeds. It may do it for a while, but won't hold together long. Mod one all you want....it still won't be a 250. There is no replacement, for displacement.

If you're keeping it stock, the only 150cc that can handle highway speeds are the 16" wheeled models. Mine tops out at 73mph, and I have driven it across the valley on the freeways many times, no problem cruising 60-65. On the surface roads I have enough power to lead the pack if I want, and enough throttle response to handle any situation. The 16" wheels are night and day different, manhole covers and potholes don't scare me anymore!
I'm waiting a full year before putting a BBK on it, I'm hoping to reach 80mph fully modded. Plenty of parts available online, most standard parts fit, and there are several dealers that carry the special sized parts. Luckily I've only had to replace a master cylinder and turn signal flasher, both are standard to all models.
Is it better to buy a light weight 150cc scooter verses a heavy scooter?... weight, is the more one has, the slower the scooter ...
Better for what? I bought my scoot at age 66, with medical problems (don't we all) and wanted the minimum weight capable on the freeways. Rented an LX150, found it was acceptable, so I bought it. The Vespa is 245 pounds, claimed. Whatever. Weight matters for acceleration. Weight does not matter with top speeds.
Gas mileage is about the same. On the Interstate my Vespa gets about 75 mpg doing 60+ mph. My 652cc motorcycle got 70 mpg doing 55-60 mph. The 150 is bare minimum and is marginal on the highway. Unless weight is a priority, go with the 250.
My 150 maxes at 58(GPS) even though the chinometer reads 72mph. I've got a high flow air filter, 115 jet in the carb, 12g rollers, taller rear tires, and an emgo, fairly open exhaust. What I'm saying is, 60mph is possible, but it'll take a bbk.

The rims concern me also. The rims on the 150t are 13 inch. Some scoots come with 12 inch and 10 inch rims. The smaller tire size, means less speed. I knew this elderly gentleman whom rode his 150 scooter with 10 inch rims, 15 miles to Walmart. Could only do 50 MPH max speed. He had about 10 cars behind him. This was the flat ground way also. It would do the mileage and had 21,000 miles on it. Another guy I met on Scootdawg said, it may be KM. But still it was impressive because 15,000 miles is good. So rim size, I did consider for higher speed.
Now there is something you are all forgetting. I am not going to ride it on a daily basis to work. I am disabled and ride for enjoyment. I choose times, when traffic is not as heavy on highways. Highways around me, are posted 55 MPH max. The lowest speed is 40 mph . One does not have to go 70 MPH on the interstate highway. But must do atleast 40 MPH. I am not going to ride a 150 on the interstate highway, just saying the speed laws are limited to 40 MPH. State highways are mainly 55 MPH highways and a person in Missouri on a 49cc scooter, has as much rights to ride on any highway as a trucker except for interstate federal highways. Just stating the laws. Is it crazy to ride a 49cc on a 55 MPH highway and make traffic angry? Yes it is. 40 MPH is the low speed for interstate highways and state highways there is no low speed. So people ride bicycles on state highways. Not sane but cars see it time to time.
I hate to slow traffic down. Why? It causes road rage. Causes unnessisary risks. So I want to be able to do 50 to 55 MPH. The speed limit. Now riding to Walmart every other week is fun but not daily. Riding 6 miles to the next town and riding through the twisting back highways, is not going to offend other drivers. Choosing times to go is important to me to avoid traffic. So like don't leave at 8 in the morning when kids are going to school, people going to work. Leave at 10 in the morning to avoid most traffic. Use common sense. Choose to leave at 1 pm and be back by 3 pm. Not during rush hour.
But that is always my motive whether on a 150 scoot or a 250 scoot.Safety first... I live in Belle MO. a town of mostly farmers. The 15 mile away town is Owensville a town of 7000. The towns in between are 1000 people with state routes. They are 55 MPH routes but traffic is hardly seen in these areas. Routes are like OO, E, EE, 55 MPH highways are like 28, 54, 63. Interstate highways are like I 44, I 70, where speed limits hit 70 MPH. Interstates are closed off to traffic lights and go straight across the State. Highways have cross traffic.
I've got a mostly unmodified Chinese 150 with 12" wheels and a very restrictive exhaust and it maxes out on level ground at less than indicated 60. Run hard it will maintain 50-55 indicated. The GPS numbers are considerably less impressive. With some tuning that may yet happen, it might do more. Depends on how much money I want to throw at it.
The smaller wheels don't have as much effect on speed as they do ride comfort and stability. 12" wheels bash through bumps and potholes that 18" wheels don't even notice. At higher speeds the small wheels are skittish where bigger wheels just get their groove going.
Secondary roads and quiet times are no problem. At busier times you just need to plan your route carefully to minimize your exposure on the big roads. I generally avoid open state and county roads because it just won't keep up with traffic if there is any uphill slope. Plenty of secondary road options though that are nearly as quick with much less traffic to worry about.
If you can afford a 250, just do it. Especially if that's what you're already used to, then you won't even have to think about it. Next best recommendation would be if you must downsize then get a newer 4-valve, fuel injected motor. (Vespa, Honda, Kymco?) They're already tuned to get the most bang for the displacement.

Well, got a new starter today, for my Bali 250. It did not start when I put it on. I recall the horn coming on and than nothing. Today the brake light came on and than nothing. I checked the fuse box and all was good. Recharged the battery, but only took about 20 minutes for the green light to come on. Put it back in the 250 and nothing. So cleaned on terminals with baking soda and water. Cleaned up cables that connected to battery. Than it ran good.
Now the starter was bad. It made a terrible grinding noise, the last time trying to start it. But it showed me that the wires need cleaning after 7 1/2 years. I could not hear the squeak in it, sitting at idle. Even reved it up and heard nothing. It am leaning to the problem with it, being either a bear or grease being added to the front axel. Can't really hear the squeak at under 30 MPH and must where a helmet at all times, which make it hard to tell where it is coming from.
But a guy has 27,000 miles on a 150T and even if kilometers, well that is about 19,000 miles. Still good for a Chinese scooter.
The rims concern me also. The rims on the 150t are 13 inch. Some scoots come with 12 inch and 10 inch rims. The smaller tire size, means less speed. I knew this elderly gentleman whom rode his 150 scooter with 10 inch rims....
My Vespa has a 110/70-11 front and a 130/70-10 in the rear. At an indicated 72 mph I am doing 65 mph per my Smartphone's GPS speedometer. I have seen 76 mph indicated,eventually.

Im 6'2 185lbs and I ride my taotao powermax 150 to work about a 12 mile trip each way and it tops out around 58mph. All I've done is replace exhaust and put a uni on, been running strong for a year and a half now.
I just ran my 150cc scooter to work, 25 miles one way. Max speed limits there and back is 50mph, mostly country roads. My scoot tops out at 52mph at 7500rpm actual speed. Motor has more, but gearing says no. Advertised speed was 59mph, no way with this set up. Performance variator is going to be my first upgrade.
