Whether a teenager or an experienced rider, you can get the best from this baby. But, it is highly popular in the beginner’s community.

That’s not a shocker. Because of its easy handling, compact size, and powerful engine, an amateur racer can get the “pro” feel without going for the risky options.

That’s why we have taken some time to research to present you with an in-depth look at the SSR 125 Top Speed, Specs, and Review. Let’s dig in.

About SSR 125 Pit Bike

Established in 2022, the SSR Motorsport has always been interested in off-roading bikes. Later, with the success of their motorcycles, the company started producing a handful number of ATVs and UTVs. Later, the company leaped into the scooter market in 2006.

All SSR products have one thing in common, stunning design and outstanding engineering. They aim to provide the value that one deserves, and they do that without sacrificing a single bit of performance.

The SSR 125 Pit Bike is one of SSR Motorsport’s most popular bikes out there. The bike is highly regarded for its 4-stroke, single-cylinder engine, crazy design, striking colors, and reliable performance. Just because it’s made in China doesn’t mean it’s cheap and bad; in fact, the opposite. The riding experience will be complete with any Honda or Yamaha out there.

SSR 125 Pit Bike Features And Review

Eca Now, in this section of SSR 125 Top Speed, Specs, and Review, we will discuss what great features this bike possesses. The features will surely intrigue you to buy one for yourself right away.

Finest Engine:

 The 125cc engine of the SSR delivers more horsepower than average. Normally, you would expect around 3-4 hp from a small 125cc engine displacement. But, the SSR 125 proves us wrong. Despite being a part of the small engine family, it makes sure the engine can generate about 7.3 HP effortlessly. Drew, a user, claimed his bike is stronger than a 175cc bike!

Plus, most 125cc engines are 2-stroke on the market. At the same time, SSR offers you the lightweight of a 125cc displacement with the power of a 4-stroke engine. That’s a pretty good deal.

Designed for the Beginners:

As a beginner, it would be hard to practice on more powerful bikes as a beginner. Those bikes require experienced riders to control. Plus, there are chances of you falling during the training. The 125cc is designed to be lightweight and cause as little harm as possible during any mishap on the road. We guess that’s why so many newbies are fond of this unit.

Efficient Air Cooling:

The air-cooled engine makes the SSR 125 very fuel-efficient. It uses no water or chemicals to cool the hot engine. As a result, you can go the extra mile with the same fuel level. It also saves a lot of engine space and requires less maintenance.

While liquid-cooled engines are famous for providing more torque, the air-cooled motor is superior in delivering better mileage.

Perfect Compression Ratio:

The SSR comes with a 9:1 compression ratio, which is the requirement of a bike engine to provide efficient performance. In comparison, a 7:1 compression ratio is considered enough for a cruising bike.

However, you can never go wrong with a slightly more compression ratio. For a 125cc engine size, the balance is pretty impressive. You can tackle highway riders or other powerful wheelers with this unit. When the piston is at the lowest point, the volume of the inner chamber is the highest. In the same way, when the piston moves to the top, the piston covers the section.

How to calculate the ratio? Your engine has the lowest volume point. Similarly, your engine also has the highest endpoint. You can calculate the ratio of these two extreme points and get your compression rate.

A higher compression rate is generally good for obvious reasons. The more volume the engine chambers have, you can store the more air and fuel.

Mikuni Carburator:

Instead of the clone carburetor, the 22mm Mikuni Carburator is used in this model. The Mikuni carb is great when you are jetting the bike.

Adjusting it can be a piece of cake if you have a bit of experience; you won’t even need a screwdriver. Besides, you can access the main jet without even taking the bowl off. Again, it gives you a better throttle response.

You would know the difference if you ever had to jet the bike yourself with a Mikuni carb. It can suddenly turn up the motor as if the bike had no idea what it was capable of doing earlier.

Compact Size:

The bike is really small and compact. The pictures online will not justify how compact the bike is in real life. The bike’s dimensions are 65 inches, 29 inches, and 40 inches. Consequently, it weighs only 129 pounds with a 0.8-gallon fuel tank. Also, the seat height is 29 inches. That means kids and adults can both ride the bike with full comfort.

Despite the size, the ground is always clear. With the wheelbase, the height will be 47 inches. So, that gives us a ground clearance of (47-40) 7 inches. You might already know that higher ground clearance prevents the bike from getting hit by road bumps. It is also a crucial factor that determines the speed level. The higher the clearance, the faster your bike can run.

Multi-color Variation:

Let’s talk about the looks. This dirt bike is available in six different colors, including hot red, blue, green, orange, white, or black. The colors are striking and will give you a feel of excitement.

We tell you one thing: a boring color pit bike is never fun to ride, and we can tell you what this one is like; it’s a true colorful madhouse.

SSR 125 Top Speed

The 125cc four-stroke engine can go as fast as 55 to 60 mph or 61 to 80 mph. The power output is around 7.3 hp at 7500 RPM. If you have researched a bit on the hp and speed of bikes before, you would know that the speed is pretty decent for a 125cc engine displacement.

The thing that contributed to this extra speed is the four-stroke SOHC engine. Normally, the 125cc engines come with a basic 2-stroke engine. But the SSR manufacturers set themselves apart in this area. And due to the extra strokes into the engine, the top speed is also increased.

How To Increase The Speed Of SSR 125?

If you want to use this Chinese pit bike for racing, you might not be satisfied with the speed. But don’t worry. There are mods available that can make a very significant increase in speed.

1. Change the Sprocket

You can install a 17 tooth sprocket instead of the 15 tooth one. A higher number of teeth in the sprocket will give your bike a speed boost right away. How to do that?

You will need an eight-millimeter 5/16 socket with a 10 mm wrench, 19 mm socket, 12mm, 13mm, and 17mm wrench. Just start by changing the front sprocket; you can increase the speed significantly. You don’t even need to change anything to the rear one.

The rule of thumb is that you need a bigger sprocket in the front and a smaller sprocket at the back to gain a top speed. But, if you change the formula and go with a bigger rear sprocket and smaller front sprocket, you will get higher torque. But not the speed you wanted.

So, we should stick with the front sprocket only. You will notice a big difference even with a slight adjustment in the sprocket tooth.

A reminder, you must get a new chain if you change the sprocket of your pit bike. Although the existing chain would cover an extra tooth, it would be wise to get a new chain altogether would be wise.

2. Air Filter And Exhaust Mod

The after-market air filter is the first mod part that gets launched. And there is a solid reason for that. Think about air and fuel as the food for your engine. The more food you can get, the better combustion or power it can generate. It is as simple as that.

Now that being said, every bike comes with its own set of air-intake, air exhaust, and some controllers adjusted into the system. Just slip a new after-market air filter and an exhaust into the system, and feel the magic. Now, your bike can gulp air like an Olympic swimmer.

3. Lighter Wheels

How can you turn the wheels quicker? Well, by forcing them to go on a diet. A lighter wheel is easier to control, and it runs faster. Plus, when the lightweight wheels get hit by a bump on the road, it is easier for the suspension to put back to its original position.

Unfortunately, that’s not the case for heavier wheels. As a beginner, you will want to have a lighter wheel as it provides better handling.

The downside is that the metal is thinner and will get out of shape sooner. If that’s not a concern for you, we suggest getting lighter wheels for this SSR pit bike.
