Design and Styling: Classic Charm with Modern Touches
Inspired by the Classic 350, the Classic 650 retains a vintage aesthetic with round headlamps, a teardrop fuel tank, and dual exhaust pipes. Key design highlights include:
- Larger 14.8-liter fuel tank for longer rides.
- Spoke wheels and steel bodywork for a traditional look.
- Four color options: Teal, Vallam Red, Bruntingthorpe Blue, and Black Chrome.
- Minimalist dual-seat design with an optional removable pillion seat.
While competitors like the KTM 390 Duke embrace sharp, modern lines, the Classic 650 stays true to its heritage.

Chassis and Handling: Built for Comfort
Riding on a steel tubular spine frame, the Classic 650 is designed for stability and comfort. It features:
- 43mm Showa telescopic forks (front) and twin shock absorbers (rear) for a balanced ride.
- Wheelbase: 1475mm | Ground clearance: 154mm, making it suitable for Indian roads.
- 19-inch front and 18-inch rear wheels enhancing its cruiser appeal.
- 243kg kerb weight, making it heavier than its rivals but improving high-speed stability.
While lighter competitors like the KTM 390 Duke offer more agility, the Classic 650 prioritizes a planted, confidence-inspiring ride.
Features and Technology: Old-School Look, Modern Convenience
Despite its retro styling, the Classic 650 includes modern touches like:
- Semi-digital instrument console with Tripper navigation.
- Full LED lighting for better visibility.
- USB charging port for convenience.
- Dual-channel ABS for enhanced safety.
While it lacks the advanced electronics of the KTM 390 Duke, it delivers the essentials expected in a premium cruiser.
Comfort and Ergonomics: Made for Relaxed Riding
Designed for long rides, the Classic 650 offers:
- Seat height: 800mm, making it accessible for most riders.
- Relaxed upright riding position with forward-set footpegs.
- Overall dimensions: 2318mm (length) | 892mm (width) | 1137mm (height).
- 14.8-liter fuel tank providing a decent touring range.
Pricing and Market Positioning
While pricing is yet to be announced, the Classic 650 is expected to follow RE’s value-for-money strategy. Given that the Interceptor 650 competes with smaller-capacity bikes like the KTM 390 Duke and Kawasaki Ninja 300, expect the Classic 650 to be competitively priced within the mid-weight cruiser category.
Verdict: Should You Buy the Classic 650?
The RE Classic 650 is a perfect blend of heritage styling, accessible performance, and modern features. While its weight may deter riders seeking nimble handling, it compensates with stability, comfort, and a timeless appeal.
If you love classic aesthetics but want a more powerful engine for touring and everyday riding, the Classic 650 is a solid choice. However, if you prefer a lightweight, aggressive machine, rivals like the KTM 390 Duke may be better suited.
