India’s electric two-wheeler segment is buzzing with innovation, and two names that stand out in the premium electric bike category are the Ultraviolette F77 and the Tork Kratos R. Both homegrown machines represent a bold leap into the future of mobility, blending performance, tech, and sustainability. But with rising fuel prices and increasing interest in performance EVs, many riders are now asking: Which one offers more for the price?
Let’s take a closer look at how the F77 and Kratos R stack up against each other in real-world expectations.
Performance & Power Delivery
The Ultraviolette F77 is built like a fighter jet on two wheels, and its numbers support that image. It packs a 30.2 kW electric motor, capable of producing 100 Nm of torque. It can sprint from 0 to 60 km/h in just 2.9 seconds, making it one of the fastest electric bikes ever produced in India. The F77 offers three riding modes — Glide, Combat, and Ballistic — for different road situations.
Tork Kratos R, on the other hand, brings 9 kW peak power and 38 Nm of torque. While it’s not as aggressive as the F77, the Kratos R is still no slouch. It accelerates smoothly, has quick throttle response, and is more than enough for urban riders who want a sporty, silent, and clean ride.
Verdict: F77 leads in outright performance, while Kratos R maintains a practical balance between speed and efficiency.
Range & Battery
Ultraviolette F77 boasts a large 10.3 kWh battery, offering up to 307 km IDC range — a class-leading figure. However, real-world numbers are typically around 180-200 km depending on riding habits. Fast charging support enables 35 km range in just 1 hour of charge.
The Tork Kratos R features a 4 kWh battery, which gives an IDC range of around 180 km, with real-world riding estimates ranging between 100-120 km. It also supports fast charging, offering about 80% charge in under an hour with the right setup.
Verdict: F77 dominates with more than double the battery capacity and significantly higher range.
Design & Build
Futuristic is the word that describes the Ultraviolette F77’s design. With sharp cuts, an aggressive riding posture, and aircraft-inspired styling, it looks like something out of a sci-fi movie. Its aluminium frame, sporty tail, and LED lighting system add to the premium feel.
The Tork Kratos R is more conventional in its approach, resembling traditional streetfighters. Its frame is solid, and the ergonomics are designed for comfort over long rides. It doesn’t scream for attention but holds a confident presence on the road.
Verdict: F77 wins for bold aesthetics, while Kratos R plays safe with commuter appeal.
Technology & Features
The F77 is loaded with tech — from a full-color TFT dashboard, smartphone connectivity, over-the-air (OTA) updates, and even geo-fencing and crash detection. It feels futuristic in every sense.
The Kratos R is no slacker either, offering its own digital dashboard, app-based features like navigation, ride analytics, and vehicle tracking. However, it doesn’t match the depth of F77’s tech ecosystem.
Verdict: F77 leads with deeper integration of advanced features.
Pricing & Value
Here’s where things get interesting. The Ultraviolette F77 is priced starting at ₹3.8 lakh (ex-showroom) for the standard variant and goes up to ₹5.5 lakh for the Recon variant. It’s a high-end performance machine and clearly aims for a niche crowd.
The Tork Kratos R is far more accessible, priced around ₹1.87 lakh (ex-showroom) after subsidies. For budget-conscious performance seekers, it offers serious value.
Verdict: Kratos R is the value-for-money choice, while F77 is for those who want premium and performance.

Conclusion: Which One Should You Pick?
Choosing between the Ultraviolette F77 and Tork Kratos R ultimately depends on what you’re looking for. If your priority is top-end performance, cutting-edge technology, and futuristic design, the F77 is unmatched. But if you want a reliable, sporty EV that won’t break the bank, the Tork Kratos R is a smart buy.
Both bikes represent the future of Indian mobility — one aiming for the sky, the other staying grounded but effective. The EV war is just beginning, and Indian riders now have real choices that don’t compromise on style or substance.
