Choosing between the Royal Enfield Interceptor 650 and the KTM 390 Adventure depends on your specific preferences and requirements. Here are some factors to consider based on the information you provided:
Height and Weight: With your height of 6'3" and weight of 90kgs, both bikes can accommodate you comfortably. The Interceptor 650 has a more relaxed and upright riding position, which may suit taller riders better. The KTM 390 Adventure offers a more aggressive riding stance, which may be more suitable if you prefer a sportier riding experience.
Riding Style: If you primarily ride in the city with occasional weekend long rides, the Interceptor 650 could be a good choice. Its torquey parallel-twin engine provides good low-end and mid-range power, which is beneficial for city riding. The Interceptor's classic styling and comfortable ergonomics make it suitable for relaxed cruising.
Performance and Off-Road Capabilities: The KTM 390 Adventure, on the other hand, is designed for more off-road and adventure-oriented riding. It has a higher ground clearance, longer suspension travel, and additional features like ABS and traction control, which can be beneficial for off-road excursions. If you have an interest in venturing off the beaten path during your weekend rides, the 390 Adventure would be a more capable option.
Maintenance and Cost: Royal Enfield motorcycles are generally known for their simplicity and ease of maintenance. They have a large service network and relatively affordable spare parts. The KTM 390 Adventure, being a more performance-oriented bike, may require more frequent maintenance and possibly higher service costs.
Aesthetics and Personal Preference: Both the Interceptor 650 and the KTM 390 Adventure have their unique visual appeal. The Interceptor offers a classic, retro-inspired design, while the 390 Adventure has a more modern and aggressive look. Your personal preference in terms of aesthetics and styling should also play a role in your decision-making process.
Ultimately, I recommend test riding both motorcycles if possible to get a feel for their handling, ergonomics, and overall riding experience. Consider your priorities in terms of riding style, comfort, performance, and maintenance, and choose the bike that aligns best with your preferences and requirements.
