As a tall rider, both the Yamaha R15 V3 and Suzuki Gixxer SF can be suitable options, but there are a few factors to consider to ensure a comfortable riding experience:
Ergonomics: The Yamaha R15 V3 has a more aggressive riding position, with forward-leaning ergonomics that are better suited for sporty riding. The Suzuki Gixxer SF, on the other hand, offers a slightly more upright riding position, which may provide better comfort for daily commuting and longer rides. If you prefer a more relaxed riding posture, the Gixxer SF might be more suitable.
Seat Height: Check the seat height of both motorcycles. The Yamaha R15 V3 has a slightly higher seat height compared to the Suzuki Gixxer SF. As a tall rider, you may find the higher seat height of the R15 V3 more accommodating for your legroom and overall comfort.
Legroom and Knee Space: Sit on both motorcycles and assess the legroom and knee space available. Your height may result in slightly more cramped legroom on both bikes, but the higher seat height and potentially longer length of the Yamaha R15 V3 might provide slightly better legroom.
Test Ride: If possible, take a test ride on both motorcycles to assess how they feel in terms of comfort, ergonomics, and overall fit for your height. This will give you a better understanding of how each bike suits your personal preferences and body type.
Ultimately, personal comfort and preference should guide your decision. Consider factors such as the intended usage, riding style, and your specific requirements. It's always recommended to test ride the motorcycles and consult with a local dealer or experienced riders before making a purchase.
