Difference Between Torque and BHP in Bikes
Anytime you plan on buying a bike make sure you compare it against multiple parameters to make the right buy. While making this purchase there are two main specifications that you must focus on– torque and BHP.
Speaking in mechanical terms, a bike's speed and carrying capability depend on its torque and BHP. Many of you may be affluent with the two terminologies and consider them the same. However, major differences exist between a bike's torque and its BHP.
What is Torque in a Bike?
In simple terms, when you purchase a bike, your seller will mention an RPM unit. This unit determines the torque of your bike.
That being told, your question can now be, what is the function of a torque? Torque determines the rotational force of the wheels. It is the force that enables the wheels to turn and move the bike forward.
If a bike has lower torque, it will help the bike to move at a faster rate. On the other hand, if a bike features higher torque, it enables it to move greater weight.
When a two-wheeler automobile can deliver a significant amount of torque at higher RPM, it simply means that the bike is powerful and features efficient torque delivery.
What is BHP in a Bike?
BHP or brake horsepower determines the rate at which the torque, gaining its power from the engine, will deliver the same to its wheels. If this delivery happens quickly, you can ride your motorbike at the same speed.
However, your two-wheeler's BHP depends on your bike's power generation, weight, and deliverability. You can easily identify how fast your bike is through its BHP unit.
What Is the Difference Between Torque and BHP in Bikes?
| Torque | BHP | |
| Formula | Torque = vertical distance x Fsinθ | BHP = Brake Horse Power |
| Meaning | Torque defines how strong the engine of your bike is. | BHP is a measure that determines how well your bike can execute that engine power. |
| Significance | It indicates the load-bearing capability of your bike. | It indicates the speed of your bike. |
| Acceleration and Turning force (with an example) | 50 BHP and 150 NM of torque mean the bike's acceleration power is not much. But its 150 NM of torque proves its turning force is pretty good. It can pull heavier loads and consistently maintain its deliverability and power. | 100 BHP and 100 NM of torque mean your bike accelerates quickly. However, the 100 NM does not guarantee a good turning force. Compared to a 150 NM, it cannot pull heavier loads or has lower deliverability and power. |
As a two-wheeler owner, be aware of your chosen bike's torque and BHP levels, as your vehicle’s performance is more or less dependent on it. Compromising the bike's torque and BHP level will hinder performance and will not make your investment worthwhile.
Now that the difference between torque and BHP is clear, identify why you are buying a bike. Is it for speed or for its eight carrying capability? Whichever your main purpose is, there are multiple bikes available today. However, compare offerings across sellers and choose accordingly.
Frequently Asked Questions
How much BHP is enough for a bike?
The amount of BHP varies among bikes and usually depends on the rider’s abilities. In general, 30 bhp is usually adequate to go anywhere and ride on any type of road. Multiple 30 bhp two-wheelers can also hit 90 mph.
Does higher torque mean faster acceleration?
The more torque your bike exhibits, the greater its acceleration will be. Thus, if you want to accelerate your bike's speed, ensure good torque.
