The Triumph Speed T4 emerges as a noteworthy contender in the 400 lineup, offering a more affordable option for those looking to enter the Triumph family. Priced approximately 23,000 rupees less than the standard Speed 400, the Speed T4 sacrifices a few features and some power to cater to budget-conscious riders. In this review, we will explore the changes, features, and overall riding experience of the Speed T4 to help you determine if this bike is the right fit for you.
Aesthetic and Functional Changes
At first glance, the Speed T4 appears quite similar to its more powerful counterpart. However, a closer inspection reveals some significant changes:
- Suspension: The most prominent change is the transition from the standard Speed 400’s upside-down forks to 43 mm telescopic forks. This adjustment enhances comfort but comes at the cost of some performance capabilities.
- Mirrors and Controls: Unlike the Speed 400, which features adjustable levers and bar-end mirrors, the Speed T4 opts for conventional stem mirrors and standard levers. This decision was influenced by customer feedback, as these mirrors improve the bike’s ability to navigate through traffic.
- Ergonomics: The Speed T4 introduces a reprofiled seat with a slimmer front and 10 mm more padding, enhancing comfort for longer rides. Additionally, the bike features new graphics and three distinct color options.
- Exhaust: The matte black exhaust not only looks appealing but is also designed to withstand high temperatures, ensuring durability over time.
Despite these changes, the Speed T4 retains LED lighting throughout, a semi-digital instrument cluster, a blacked-out radiator grill, and a bash plate, preserving the signature look and feel of Triumph bikes.
Mechanical Specifications
Engine Performance
The Speed T4 is powered by a 399cc TR series engine, which has been intentionally detuned to produce 31 BHP and 36 Nm of peak torque. The key selling point is its ability to deliver torque more effectively, with 85% of the 36 Nm available from as low as 2,200 RPM. This makes the bike feel more tractable and user-friendly, particularly in urban settings.
The modifications to the engine include:
- Heavier Flywheel: This enhancement helps smooth out power delivery at lower speeds.
- Revised Throttle Body Control System: This modification allows for better throttle response, improving the riding experience.
- Sprocket Changes: A smaller rear sprocket, reduced from 43 to 39 teeth, results in taller gearing, which contributes to improved low-end torque.

Riding Experience
The Speed T4 is designed for city riding and provides a comfortable experience at highway speeds. However, it may struggle during spirited rides, as the reduced power output limits top-end performance. Triumph has also removed traction control and opted for a traditional cable-operated throttle, moving away from the ride-by-wire system found in the Speed 400. While the absence of traction control may not be a significant drawback, the cable throttle can feel less responsive at lower speeds.
Chassis and Suspension
The Speed T4 shares the same steel tubular perimeter frame and 17-inch ten-spoke cast aluminum wheels as the Speed 400. However, its riding dynamics differ due to several adjustments:
- Suspension Setup: The 43 mm telescopic forks provide improved comfort over rough roads, resulting in a slightly plusher ride compared to the Speed 400.
- Tire Specifications: The Speed T4 is equipped with Bully MRF tires, which feature a stiffer profile and narrower rear width, enhancing the overall riding experience.
- Longer Wheelbase: The bike boasts a 20 mm longer wheelbase due to a modified rear rail angle, contributing to improved stability during rides.
Braking System
Braking duties are managed by a 300 mm disc at the front and a 230 mm disc at the rear, supported by dual-channel ABS from Bosch. This system provides reliable stopping power and enhances rider confidence.
Conclusion
The Triumph Speed T4 stands out as a budget-friendly option in the 400 lineup, offering a comfortable and capable riding experience. While it sacrifices some features and power, it performs well as a practical daily rider with excellent touring potential.
However, the 23,000 rupee price difference between the Speed T4 and the Speed 400 raises questions about its value proposition. The Speed 400’s advantages, such as upside-down forks, traction control, and grippier tires, make it a compelling alternative. Triumph may find it challenging to sell the T4 unless it can justify its price point more effectively, potentially by lowering it closer to the 1.8 lakh rupee mark.
