Bajaj’s ExhausTEC Explained: How It Improves Torque and Pickup

Early morning rush in Colombo or delivering goods across the packed streets of Negombo, having a motorcycle that responds quickly and handles weight with ease is essential.

That’s where Bajaj’s ExhausTEC technology comes in as a clever addition to the exhaust system that improves torque and pickup at low engine speeds.

From daily deliveries in Galle to long rides through the undulating roads near Nuwara Eliya, riders across Sri Lanka are already experiencing the difference.

Let’s explore what makes ExhausTEC so useful for urban riders, delivery professionals, and everyday commuters.

What is Bajaj ExhausTEC technology?

ExhausTEC is an advanced component that is integrated into the exhaust system of Bajaj motorcycles. It stands for Exhaust Torque Expansion Chamber, which improves low-end torque and aids the power of the bike at low engine speeds. This technology makes improvements without reducing fuel efficiency or engine performance.

The ExhausTEC technology was introduced in Bajaj’s DTS-i (Digital Twin Spark Ignition) engine lineup. This change was immediately felt by riders, especially when climbing rougher terrain or accelerating from a standstill.

Why does Low End Torque matter?

Before going further into the mechanics of the ExhausTEC technology, we should understand why torque and pickup matter for everyday riders.

Torque is the rotational force that allows the bike to move from a static position and power through rougher terrain or when it has a heavy load. Pickup, on the other hand, determines how fast the bike gains speed, especially in lower gear ranges.

In Sri Lankan cities like Colombo, with stop-start traffic and hilly roads, strong low-end torque helps riders:

• Accelerate faster without constantly downshifting
• Ride comfortably even with pillion or parcel weight
• Save fuel by avoiding engine strain
• Enjoy a smoother ride through daily congestion

How does Bajaj ExhausTEC work?

The ExhuasTEC system innovates by adding a small expansion chamber into the exhaust pipe. This chamber has been placed in order to tune and manipulate pressure waves that are created by the exhaust gases.

The ExhuasTEC process can be broken down as such:

• When the engine combusts fuel, exhaust gases are generated that exit through the exhaust pipe in pulses.
• These pulses are modified by the ExhuasTEC chamber to create an optimum back pressure at lower than average RPMs.
• This optimised back pressure helps the engine retain more exhaust gases briefly, which improves combustion efficiency and scavenging. This results in an increase in torque output.
• The Bajaj ExhausTEC process ensures a smoother and more responsive experience for the rider at lower speeds, especially at first, second, or third gears.

The Bajaj ExhausTEC system allows the bike to ‘breathe better’ when riding and ensures a smoother and more fuel-efficient experience for riders at lower engine speeds.

What are the key benefits that Bajaj ExhausTEC provides?

Here’s what riders in Sri Lanka can expect from ExhausTEC-equipped motorcycles:

• Improved Low End Torque- ExhausTEC improves pulling power at lower RPMs, making it easier to climb steep roads in areas like Hatton or Bandarawela. This is especially helpful for delivery riders carrying loads through city traffic or rural roads.
• Improved Pickup- The Bajaj ExhuasTEC technology enhances pickup, streamlining and improving acceleration. This makes sure that the bike can reach its desired speed quickly and smoothly from 0 to 60. An enhanced pickup allows riders to zip through the streets of Colombo smoothly.
• Improved Fuel Efficiency- Due to the ExhausTEC technology, the rider rarely needs to downshift or rev the engine too hard. This results in improved fuel efficiency and increased mileage. Daily commuters and delivery professionals significantly benefit from improved mileage as they usually have to undertake long journeys on a daily basis.
• Improved Engine Longevity- The Bajaj ExhusTEC technology reduces engine strain due to a better torque delivery, and thereby increases the lifetime of the engine. Therefore, it helps reduce the maintenance costs of the bike and helps riders have a better experience with their ride.
• Smoother Riding Experience- Even in wet or uneven areas like Ratnapura or Badulla, ExhausTEC adds stability and comfort. The Bajaj ExhausTEC technology ensures that the bike feels more responsive, allowing the rider to feel in control while cruising through Colombo or its suburbs.

Who benefits the most from the Bajaj ExhausTEC technology?

While ExhausTEC supports all riders, it’s particularly helpful for:

• Daily commuters navigating Colombo’s stop-and-go traffic
• Delivery professionals in towns like Kurunegala or Matara carrying heavy loads
• Students and working professionals looking for reliable, stylish, and responsive bikes
• New riders who need smoother pickup and better control
• Suburban explorers who ride on a mix of paved and unpaved roads

Bajaj bikes equipped with ExhausTEC technology

• Bajaj CT 100 ES : The CT 100 ES is the most fuel-efficient option that Bajaj bikes offer. It is equipped with a 4-stroke single-cylinder, naturally air-cooled engine featuring Bajaj ExhausTEC technology. With improved control and the best-in-class safety ensured by a rugged build and drum brake system, the CT 100 ES is one of the most efficient options for daily commuters and Delivery professionals.
• Bajaj Discover 125 Disc : The Discover 125 Disc comes equipped with a 4 Stroke Single cylinder, DTS-i with ExhausTEC with a max torque of 11 @ 5500 (NM @ RPM). Another favourite for daily commuters and Delivery Professionals, the Discover 125 Disc provides a fuel-efficient experience for Bajaj riders.

Cruise through the streets of Colombo with ExhuasTEC-equipped Bajaj Bikes

Whether you’re zipping through Colombo or cruising through the roads near Anuradhapura, Bajaj’s ExhausTEC technology ensures a confident, controlled, and fuel-efficient riding experience.

It’s not just about engine mechanics, it’s about the everyday difference in how your ride feels. Smoother starts, fewer gear shifts, better acceleration, these small changes make a big impact when you're riding every day.
