Both the Honda CB650R and the Yamaha XSR700 are excellent motorcycles with their own unique characteristics. Considering your requirements for open road commuting, touring, reliability, and comfort, let's compare some aspects to help you make a decision:
Ergonomics: As a taller rider at 6'4", you may find the Honda CB650R more accommodating. It has a slightly more upright riding position, which can be more comfortable for longer rides. The Yamaha XSR700 has a slightly sportier, forward-leaning riding position.
Engine Performance: Both motorcycles offer good performance, but the Honda CB650R has a four-cylinder engine, while the Yamaha XSR700 features a twin-cylinder engine. The CB650R may provide slightly smoother power delivery and more low-end torque, which can be beneficial for relaxed riding and commuting.
Handling: Both bikes have capable handling, but the Yamaha XSR700 has a slight edge in terms of agility and maneuverability, making it a bit more suitable for twisty rural roads. The CB650R, on the other hand, may offer a more stable and planted feel on straight highways.
Styling: This is subjective, as the choice between the modern and aggressive styling of the CB650R and the retro-inspired design of the XSR700 depends on personal preference.
Considering your requirements for reliability and comfort, both the Honda CB650R and the Yamaha XSR700 have good track records. However, it's always recommended to check user reviews, visit dealerships, and even take test rides to assess which motorcycle feels more comfortable and suits your preferences best.
Ultimately, your decision should be based on your personal comfort, preferences, and the specific features that matter most to you in terms of ergonomics, power delivery, and handling characteristics.
