Design & Technology

The 5-inch TFT color display pairs with your smartphone via Bluetooth, offering navigation, call info, and ride customization — a premium touch uncommon on bikes under $7,000 MSRP in the USA. (Motorcycle News)
Performance & Ride Quality
The LC4c single delivers strong mid-range power and a rev-happy character that makes the Duke feel faster than its displacement suggests. Smooth throttle response and a crisp quickshifter (on many models) make gear changes satisfying and precise. (Motorcycle News)
Handling is a highlight — nimble, direct, and confidence-inspiring. Light weight and sharp steering translate well to stop-and-go city riding, while the bike holds its own on twisty roads. (MCNews)
