2016 KTM RC390: The KTM RC390 is a sporty and lightweight motorcycle known for its aggressive styling and nimble handling. While it offers exciting performance, it may be a bit too powerful for an inexperienced rider. It's generally recommended to start with a bike that has a lower power output to build up your skills and confidence gradually.
2017 Yamaha YZF-R3: The Yamaha YZF-R3 is a popular choice for beginners due to its manageable power, user-friendly nature, and forgiving handling. It features a 321cc parallel-twin engine, providing enough power for enjoyable rides while still being approachable for new riders. The YZF-R3 has a comfortable riding position and offers a good balance between performance and ease of use.
2004 Triumph Daytona: The 2004 Triumph Daytona is a more powerful and performance-oriented motorcycle compared to the YZF-R3. It comes with a 600cc engine, which may be too much for a novice rider. Triumph Daytonas are known for their aggressive riding position and focused handling, making them better suited for riders with more experience.
2003 Suzuki GSX-R: The Suzuki GSX-R is a legendary sportbike with a strong focus on performance. The GSX-R models are high-performance motorcycles designed for experienced riders who are looking for exhilarating speed and precise handling. It's not recommended as a first bike due to its aggressive nature and powerful engine.
Considering your status as a beginner rider, the Yamaha YZF-R3 would be the most suitable option from the list. Its approachable power, user-friendly handling, and comfortable riding position will help you develop your skills and build confidence on the road. Remember to invest in proper safety gear and take a motorcycle training course to ensure a safe and enjoyable riding experience.
