Now, let’s compare both bikes in detail.

Engine and Performance

The biggest difference between these motorcycles lies in how they deliver power.

KTM Duke 390

The KTM Duke 390 is powered by a 398.63cc liquid-cooled, single-cylinder engine producing approximately 41.5 PS at 8,600 rpm and 33.5 Nm of torque at 7,000 rpm.

This engine loves high revs and delivers its best performance when pushed hard. Riders who enjoy fast acceleration, spirited riding, and aggressive corner exits will appreciate the Duke’s energetic character.

KTM also offers the more performance-focused Duke 390 R, producing around 46 PS, making it one of the most powerful motorcycles in its class.

Royal Enfield Guerrilla 450

The Guerrilla 450 shares its 452cc liquid-cooled Sherpa engine with the Himalayan 450.

It produces 40.02 PS at 8,000 rpm and a healthy 40 Nm of torque at just 5,500 rpm.

Although it makes slightly less peak power than the Duke, it offers significantly stronger low-end and mid-range torque. This makes everyday riding smoother, especially in city traffic, where fewer gear changes are required.

Performance Verdict

• KTM Duke 390: Better peak power and thrilling high-speed performance.
• Royal Enfield Guerrilla 450: Stronger low-end torque and a more relaxed riding experience.

Mileage and Running Costs

Both motorcycles offer respectable fuel efficiency for their performance levels.

• KTM Duke 390: Around 30 km/l
• Royal Enfield Guerrilla 450: Around 28–29.5 km/l

The difference in mileage is relatively small, and actual fuel economy depends on riding style, traffic, and maintenance.

The Guerrilla gains an advantage with its 11-litre fuel tank, allowing longer rides between fuel stops, making it a better companion for weekend touring.

Price Comparison

Price is one of the Guerrilla 450’s strongest selling points.

Bike	Approx. Ex-showroom Price
Royal Enfield Guerrilla 450	₹2.39–2.54 lakh
KTM Duke 390	₹2.84 lakh onwards

Depending on the variant, the Guerrilla can cost ₹30,000 to ₹95,000 less than the Duke.

For riders upgrading from a 350cc motorcycle or buying their first premium bike, the Guerrilla offers excellent value for money.
