Bs4 to bs6: a revolution in ktm duke 250 performance

The KTM Duke 250 is a popular motorcycle in India, known for its aggressive styling, powerful engine, and agile handling. With the implementation of stricter emission norms, the Duke 250 has undergone significant updates to meet BS6 standards. This blog post will provide a comprehensive comparison between the BS4 and BS6 versions of the KTM Duke 250, highlighting the key differences and helping you make an informed decision.

Engine and Performance

The most notable difference between the BS4 and BS6 Duke 250 lies in their engines. The BS4 model features a 248.8cc, single-cylinder, liquid-cooled engine that produces 30 PS of power at 9000 rpm and 24 Nm of torque at 7500 rpm. The BS6 model, on the other hand, has a slightly smaller 248.77cc engine, but it produces marginally higher power and torque figures: 30.4 PS at 9250 rpm and 24 Nm at 7500 rpm. This difference in output is attributed to the addition of an electronic fuel injection system in the BS6 model, which optimizes fuel delivery and combustion efficiency.

Fuel Efficiency and Emissions

The BS6 Duke 250 boasts improved fuel efficiency compared to its BS4 predecessor. KTM claims the BS6 model can deliver up to 35 kmpl in real-world riding conditions, while the BS4 model typically achieved around 30-32 kmpl. This improvement in fuel efficiency is primarily due to the more efficient fuel injection system and revised engine mapping. Additionally, the BS6 Duke 250 meets the stringent Bharat Stage 6 (BS6) emission norms, which significantly reduce harmful pollutants emitted by the motorcycle.

Features and Technology

In terms of features and technology, both the BS4 and BS6 Duke 250 are well-equipped. They come standard with a fully digital instrument cluster, LED lighting, and single-channel ABS. However, the BS6 model introduces a few additional features that enhance the riding experience. These include a slipper clutch, which prevents rear-wheel lockup during aggressive downshifts, and a new side-mounted exhaust system that delivers a more throaty exhaust note. The BS6 model also features a revised throttle response for smoother acceleration and improved rideability in urban conditions.

Suspension and Handling

The suspension and handling characteristics of the BS4 and BS6 Duke 250 are largely similar. Both models feature a 43mm upside-down front fork and a preload-adjustable rear monoshock. The suspension setup provides a comfortable ride quality while offering excellent handling and stability. The BS6 model, however, has slightly revised suspension settings that are said to improve handling at higher speeds.

Styling and Ergonomics

The overall styling and ergonomics of the BS4 and BS6 Duke 250 remain largely unchanged. Both models feature an aggressive and sporty design with a compact silhouette and a comfortable riding position. The BS6 model, however, features a new color scheme and graphics, giving it a more modern and distinctive look.

Price and Availability

The KTM Duke 250 BS6 is slightly more expensive than the BS4 model. The BS4 Duke 250 was priced around INR 1.75 lakh (ex-showroom), while the BS6 model is currently priced at INR 2.09 lakh (ex-showroom). The BS6 Duke 250 is available in a wider range of color options, including Orange, White, and Black.

Verdict: Which One Should You Choose?

The choice between the KTM Duke 250 BS4 and BS6 depends on your specific requirements and budget. If you are looking for a more affordable option with proven reliability, the BS4 Duke 250 is still a great choice. However, if you prioritize fuel efficiency, improved performance, and the latest features, the BS6 Duke 250 is the better choice. Ultimately, both models offer an exhilarating riding experience and are well-suited for urban commuting and spirited weekend rides.
