Both the Suzuki Gixxer and Honda CB Hornet 160R are popular motorcycles in the 150-160cc segment and offer decent performance and features. However, for tall riders (6 feet or taller), the Honda CB Hornet 160R might be a better choice due to its slightly more spacious riding ergonomics.
The Honda CB Hornet 160R has a relatively upright seating position with a wide handlebar, which provides better comfort and control for taller riders. It also offers a longer and wider seat, which can accommodate taller riders more comfortably.
On the other hand, the Suzuki Gixxer has a slightly more aggressive riding posture with slightly forward-set footpegs and a narrower handlebar. While it can still be suitable for taller riders, it may feel slightly cramped compared to the Hornet for someone above 6 feet.
Ultimately, it's essential to test ride both motorcycles if possible to determine which one feels more comfortable and suits your riding preferences. Personal comfort and fit should be the primary factors when choosing a motorcycle, especially for taller riders.
