Pros & Cons

Pros
Cons

KTM Duke 390
- Sharp brakes
- Incredibly exciting performance
- Suspension feels comfortable even in stock setup
- Low seat height makes it accessible to different riders
- Feature-packed console
- Great engine heat dissipation - riders won't feel much engine heat on their legs, even when the bike is not moving
Aprilia RS 457
- Looks - looks sporty, aggressive and premium. Good build quality and sharp design mean it attracts a lot of attention
- Engine - lots of torque throughout the rev range makes commuting very easy. Quick overtakes even in a gear higher are effortless
- Tyres - the TVS Eurogrip Protorq Extreme tyres are fantastic both in dry and wet conditions, no complaints there
- Features - the TFT console is user-friendly and offers a lot of useful information
- Price - at Rs 4.10 lakh (ex-showroom Delhi), it is the mo

KTM Duke 390
- Aggressive design might not appeal to everyone
- Some panel gaps are not nice to look at
- Metzeler tyres aren't very grippy when you ride aggressively
- Engine still has some vibrations
Aprilia RS 457
- Riding posture - the clip-on handlebar is low-set and on the committed side, not the best for everyday commuting
- Firm rear suspension - the RS 457’s monoshock is on the firmer side and lighter riders will be tossed around a bit when going through potholes and sharp speed breakers
- Reliability - the RS 457 is coming out of a factory that’s never made a bike before so its reliability and how Aprilia handles its after-sales service is yet to be seen

390 is better in segment
Looking so pretty 😍 the row power acceleration is most better than 300 cc bike seat High so comfortable and maintenance cost is on pocket money This allows for slick, clutchless up and downshifts, improving shift times and acceleration. I love this bike and suggest for everyone I also prefer to my friend circle..

RS 457 - Bike that does it all
I bought this bike last year in December and man this bike is an absolute bang for the money. Before this, I had an RS 200 and man the difference in power, features and comfort is so noticeable. I ride this bike on a daily basis and I am 100% satisfied with its performance and mileage. Though I don't ride it recklessly or full throttle very often but when I do it simply puts a big smile on my face and pumps up the adrenaline bar to its max. Overall, its a very good bike and will definitely put a smile to your face whenever you ride it.

BEAST FOR REAL
The Aprilia RS 457 is a new age supersport which cuts the line between a beginner's bike and a track beast, all while being simple to use. Thanks to its older brother, the RS 660, it provides a taste of power with race like experience, and features along with lethal Italian design. Good Handling...
