The Aprilia RS-457 vs. KTM RC-390: A Rider’s Love Affair (And Why He’s Still Not Buying)

Middleweight sportbikes are like that perfect slice of pizza—exciting, satisfying, and leaving you wanting more. The Aprilia RS-457 and KTM RC-390 are two hot contenders in this space, promising adrenaline without breaking the bank. After test-riding both, one rider walked away smitten by the Aprilia but still holding onto his wallet. Here’s why.

First Impressions: The Italian Charmer vs. The Austrian Beast
The Aprilia RS-457 is a head-turner. With sharp lines, a sleek twin-headlight setup, and Aprilia’s racing DNA oozing from every angle, it looks like a mini RSV4. The fit and finish feel premium, and the riding posture is aggressive but not back-breaking. Then there’s the KTM RC-390—a bike that screams “track-ready” with its neon orange accents, minimalist design, and a riding stance that’s very committed. It’s lighter and more compact, but the Aprilia’s sophistication shines through in details like the TFT display and switchgear.

Riding the Aprilia RS-457: Smooth Operator
The RS-457’s 457cc parallel-twin engine is a revelation. It’s smooth, linear, and surprisingly punchy. The power builds steadily, making it beginner-friendly but still thrilling for seasoned riders. The chassis feels planted, especially in corners, and the suspension strikes a balance between sporty stiffness and everyday comfort. On highways, it’s stable; in city traffic, it’s manageable. What stands out is how refined it feels—like a proper “big bike” without the intimidating power surge.

KTM RC-390: The Pocket Rocket
The RC-390, with its 373cc single-cylinder engine, is a firecracker. It’s raw, loud, and loves to rev. The acceleration is aggressive, and the lightweight chassis lets you flick it around corners like a bicycle. But there’s a catch: the ride is harsh. The stiff suspension and ultra-aggressive riding position make it a blast on smooth roads or tracks but punishing on bumpy city streets. It’s a bike that demands commitment—you either embrace its wild side or walk away.

Why the Aprilia Stole the Rider’s Heart
The RS-457 feels like a grown-up bike. The twin-cylinder engine’s refinement, the premium build quality, and the confidence-inspiring handling make it versatile. You could ride it daily, hit twisties on weekends, or even tour comfortably. The KTM, while thrilling, feels niche—it’s a weekend warrior or track toy. For riders seeking a balance between fun and practicality, the Aprilia hits the sweet spot.

So… Why Isn’t He Buying It Yet?
Here’s the twist: love doesn’t always lead to marriage. The Aprilia’s price tag (reportedly higher than the KTM’s) is a hurdle. Add to that concerns about Aprilia’s service network in some regions—spare parts and skilled mechanics aren’t as widespread as KTM’s. The RC-390, while less polished, is a proven machine with a strong after-sales ecosystem. There’s also the “wait-and-watch” factor. The RS-457 is new, and riders might want to see how it holds up in the long run before taking the plunge.

The Final Word
The Aprilia RS-457 is a compelling package—stylish, refined, and fun. But the KTM RC-390’s aggressive pricing and established reputation keep it in the game. For now, the rider’s heart says Aprilia, but his head says, “Let’s see.” In the middleweight battle, there’s no wrong choice—just what fits your priorities: sophistication or savagery.
