Speed is thrilling and gives you a fantastic adrenaline rush. For that reason, we will research the 150 cc category of scooters and look at the variety of speeds you can get from this amusing vehicle. A 150 cc scooter’s top speed can fall in the range of 55 to 70 mph. Of course, because the scooter being talked about has no added enhancements and is fully stock.
Aspects That Can Impact the Top Speed
Does your scooter use a four-stroke or a two-stroke motor? There are numerous reasons why you would get a top speed of that range. The scooter’s motor is a significant factor that decides the maximum speed. Other than that, engine efficiency also plays a vital role. It’s a general rule that if the scooter is older, its technology is also outdated. If the technology is obsolete, that means the scooter’s efficiency will be compromised.
Appropriate Engine Break-in Can Enhance Speed
Of course, substandard maintenance of can vastly reduces your scooter’s performance. Sticking to an appropriate maintenance plan can significantly improve the scooter’s function. As your engine starts breaking in, you will be able to observe a slight enhancement in horsepower. Furthermore, regular lubrication of mechanical parts decreases the friction between them, which increases your engine’s life. You may also experience an added reward for looking after your scooter correctly.
Weight is also another critical factor in impacting the top speed. This does not necessarily mean your vehicle’s weight, but the driver’s importance or passenger can matter much. When the maximum speed is being studied, researchers try their best to keep all research fair components. To do that, they maintain an approximation of 200 lb as the weight of the driver. If that is not supported under consideration, then the person reviewing the scooter should record the test driver’s weight.
Finally, the more accessories you add to your scooter will also vary the top speed. These accessories can include side bags and tail top boxes. Other than that, your items stored in the under-seat storage compartment matter as well.
How Top Speeds Can Fluctuate?
The wind has a significant role when it comes to speed. Keep in mind that scooters are lightweight and small vehicles. Variables like headwinds are something that you may not be used to. However, they are essential enough to be included. Any experienced driver can notice a fall of about 5 – 10 mph in speed when the headwind is more substantial than a typical light breeze.
On the contrary, it is the tailwind. This does the exact opposite of the headwind. It gives your scooter an additional force forward. This means that your scooter’s motor will not have to put as much effort into maintaining your current speed. By now, you may have figured out that a tailwind will increase your gas mileage, while a headwind will do the opposite.
For aerodynamics, you can not do anything regarding the scooter’s stock design itself. However, adding accessories to your scooter is in your hands; as mentioned earlier, accessories such as side bags and tail top boxes put additional weight on the scooter. But, that’s not just the case because their drag can cause your scooter to slow down.
Moreover, installing the voluntary windshield that manufacturers will recommend can severely impact the speed as well. Indeed, it serves its function by reducing the number of debris and bugs hitting the driver, but it will result in heavy air resistance and slow your scooter.
Some may argue that installing the windshield will not matter either way because the rider will cause similar air resistance if the windshield is missing. However, the reasonable counter-argument would be that if the windshield is not installed, the rider has the option of leaning forward while driving. This will decrease his surface area coming in contact with air and thus increase his scooter’s speed.
This is also a significant factor in a scooter’s performance. If you live in a city nearer to sea level, you will have more oxygen in the atmosphere. With more oxygen available, the engine will generate a more productive output of energy, which will, in turn, benefit the performance of your scooter.
Use as Intended
One important thing to remember is that scooters were never designed to be high-speed vehicles. They have smaller motors, in our case 150cc. Their braking and handling are not intended to cut corners and make those sudden stops you may expect from sports bikes. Instead, their producers’ center of attention is critical aspects like safety, fuel efficiency, and comfort.
A 4 Stroke Engine vs. Two Stroke Engine
Honestly, moving fast is an exhilarating experience, but the excitement of fast acceleration is an equally enjoyable experience.
Typically, four-stroke engines are not designed to shoot off. Instead, they can achieve more incredible speeds. On the other hand, two-stroke engines pick up speed fast but have to settle for lower top speeds.
Benefits of a 2 Stroke Engine
- Pistons are firing on every other stroke instead of every fourth. This results in an addition of 30% to 40% to engine power.
- This guarantees that the probability of something going wrong is going below. For instance, two-stroke engines do not have values.
- Lighter weight than a four-stroke engine.
- Lower repair costs.
- As mentioned above, the chances of things going are low, so, fewer cases of breakdowns.
- Superior torque is produced when at high RPMs.
Benefits of a 4 Stroke Engine
Superior Reliability and Durability
Four-stroke engines are designed in such a way that they operate at lower RPMs. This means that they end up doing a lower amount of work. That results in a longer life for the engine before it has to be overhauled.
Less Pollution Due to Cleaner Combustion
This is made possible because these engines use only gas as fuel and not a mixture of gas or oil.
Greater Fuel Economy
The engine uses fuel on every fourth stroke.
Greater Torque Generated on Lower Rpms
This feature supplies the rider with an extra push when needed. Going uphill is a great example where this feature chimes in to help.
The engine producer softer sounds because the combustion occurs on another stroke than the lubrication.
We hope that this article answered any questions you had in your mind and that it provided you with sufficient information regarding this topic. We want to state that if you are interested in buying a new vehicle that is fast and has excellent maneuverability, then buy a sports bike. Scooters are designed for more comfortable and casual rides instead of heart-pumping ones.
