Aprilia lists a 457 cc parallel twin with 35 kW (47.6 HP) and 43.5 Nm, while the KTM’s output and pricing vary by market and Honda’s U.S. specification page does not state horsepower or torque. The useful choice depends on your market, the exact model offered there, and how each bike feels in a test ride.
What the published specifications establish
The figures below come from manufacturers, not a controlled comparison test. The KTM entries refer to different markets and should not be combined into a single universal specification. Aprilia’s 2025 U.S. technical sheet and Honda’s 2025 U.S. page likewise describe their respective market offerings.
| Model and source market | Engine and claimed output | Weight, seat and fuel | Price context |
|---|---|---|---|
| 2025 Aprilia Tuono 457, U.S. technical sheet | 457 cc liquid-cooled parallel twin; 35 kW (47.6 HP) at 9,400 rpm; 43.5 Nm at 6,700 rpm | 385 lb wet under the sheet’s stated EU guideline; 31.4-inch seat; 3.6-gallon tank | No current U.S. price established by the cited technical sheet |
| 2025 Honda CB500F, U.S. specification | 471 cc liquid-cooled parallel twin; horsepower and torque are not stated on the cited specification page | 414 lb curb weight; 31.1-inch seat; 4.5-gallon tank | $6,899 base MSRP plus $600 destination |
| Gen-3 KTM 390 Duke, India, February 2025 Bajaj announcement | 399 cc single; 46 PS; 39 Nm | Weight and seat height not stated in the announcement | Rs 2.95 lakh announced price |
| MY2025 KTM 390 Duke, KTM Japan announcement quoting EU specifications | 398.7 cc; 33 kW (45 PS); 39 Nm | 165 kg including fuel; 820 mm seat | Japan announcement lists ¥829,000 including 10% tax, but cautions that the cited figures are EU specifications and Japanese specifications may differ |

Do not read the Aprilia’s 385 lb and Honda’s 414 lb as a direct 29 lb like-for-like difference: Aprilia labels its figure wet weight under an EU guideline, while Honda calls its figure curb weight. The cited sources do not establish identical weighing methods. Similarly, India’s 46 PS KTM claim and the EU-spec 45 PS value reported by KTM Japan are distinct market/source entries, not a contradiction to resolve by choosing one globally.

How the engines compare on paper
Aprilia Tuono 457: parallel-twin output is specified
Aprilia gives both power and torque figures for its 457 cc liquid-cooled parallel twin: 35 kW (47.6 HP) at 9,400 rpm and 43.5 Nm at 6,700 rpm. It also lists a six-speed transmission and slipper clutch. These numbers describe the maker’s claimed output; they do not show how quickly the bike accelerates, how the power is delivered on the road, or how it compares in a measured test.
Honda CB500F: larger twin, incomplete output comparison
The cited U.S. Honda page specifies a 471 cc parallel twin and a six-speed transmission, but does not provide horsepower or torque. Engine capacity alone cannot settle which bike is faster or more flexible. Riders comparing the two should use a local specification sheet for the exact model and, where possible, ride both rather than infer performance from displacement.

KTM 390 Duke: single-cylinder character, market-specific numbers
Bajaj’s India-market announcement identifies the Gen-3 Duke as a 399 cc single producing 46 PS and 39 Nm. KTM Japan’s MY2025 notice quotes EU figures of 33 kW (45 PS) and 39 Nm for a 398.7 cc engine, while warning that Japanese specifications can differ. The sources establish the KTM’s single-cylinder layout and these market-specific claims, but not comparative acceleration, smoothness, fuel economy or vibration.
Equipment and chassis details that may shape a shortlist
Aprilia Tuono 457
Aprilia’s model page describes a 5-inch TFT, three riding modes, full LED lighting and dual-mode Bosch dual-channel ABS. It also lists adjustable suspension, 17-inch wheels and 110/70 front and 150/60 rear tires. The technical sheet specifies a twin-spar aluminum frame, preload-adjustable 41 mm fork and rear monoshock, a 320 mm front disc with a radial four-piston ByBre caliper, and a 220 mm rear disc. These are equipment claims, not independent assessments of braking or handling.

Aprilia positions the bike for day-to-day riding and leisure use in a Piaggio Group announcement dated March 27, 2025. That is the manufacturer’s intended positioning, not a rider-review finding.
Honda CB500F
Honda’s 2025 U.S. specification lists a 41 mm Showa SFF-BP inverted fork, twin 296 mm front discs and ABS. Its 31.1-inch seat is 0.3 inch lower than Aprilia’s listed 31.4 inches, though seat-height figures alone do not determine how secure a rider will feel at a stop; seat shape and suspension sag matter too.

Price is a local comparison, not a global ranking
The available prices use different currencies, markets and tax or fee conventions. Honda’s cited U.S. page lists a $6,899 base MSRP plus $600 destination for the 2025 CB500F. Bajaj announced Rs 2.95 lakh for the Gen-3 KTM 390 Duke in India in February 2025. KTM Japan lists ¥829,000 including 10% tax in its MY2025 notice, alongside a warning that the quoted specifications are EU figures and Japanese specifications may differ. Aprilia’s cited U.S. technical sheet does not establish a current U.S. price.
Aprilia UK listed a £6,175 recommended retail price including VAT, but that is a UK price, not a basis for ranking U.S. or India-market offers. The same UK page’s £600 accessories offer was stated to run until July 31, 2026, so it has expired as of October 8, 2026. Ask local dealers for current, out-the-door quotes and confirm model year, destination or delivery fees, registration costs, and any included equipment before deciding.

Quick Recap
What to compare before choosing
- Exact local model: Verify model year, engine specification, electronics, and included equipment for the country where you will buy. The KTM announcements show why market labels matter.
- Fit at a stop: Compare seat height, width and shape in person. The listed Tuono and CB500F heights are close, but the sources do not establish which will fit an individual rider better.
- Ride feel: Test ride where possible to judge throttle response, engine character, vibration, low-speed control, comfort and handling. Manufacturer specifications cannot answer those questions.
- Ownership support: Check nearby dealer access, warranty terms, parts availability, service intervals and local service pricing. The Honda U.S. page lists a one-year transferable limited warranty; the cited sources do not establish comparable warranty coverage or ownership-cost advantages for all three bikes and markets.
- Total purchase cost: Compare written local quotes on the same basis, including taxes, destination or delivery, registration and fees rather than converting list prices across countries.
