When selecting the appropriate size quad, it's important to consider factors such as your height, weight, riding style, and experience level. Given that you're already finding your 250 Yamaha Raptor too small, it makes sense to explore larger options.
The Yamaha YFZr and the Yamaha Raptor are both popular choices for riders looking for more power and size. Here's a comparison to help you decide between the two:
Yamaha YFZr 450: The YFZr 450 is a high-performance quad designed for aggressive riding and racing. It offers a powerful engine and responsive handling, making it suitable for experienced riders. It's important to note that this quad is lighter than the 700 Raptor, which can be an advantage in certain situations.
Yamaha Raptor 700: The Raptor 700 is a larger quad with a more powerful engine, providing ample torque and top speed. It offers a comfortable ride and is well-suited for riders who prefer a balance between sporty performance and recreational riding. The increased size and weight of the Raptor 700 may offer improved stability for taller and heavier riders.
Given your height of 6'2" and weight of 225 lbs, both options could be suitable for you. However, if you're primarily looking for a more powerful and larger quad, the Yamaha Raptor 700 might be a better choice due to its larger size and increased power.
Ultimately, I would recommend visiting a local dealership or contacting Yamaha directly to get a hands-on experience with both models and discuss your specific needs and preferences with experts. They can provide you with more detailed guidance based on your riding style, terrain, and other factors to help you make an informed decision.
