Part Availability: Excellent KTM has one of the most widespread dealer networks worldwide. Parts are generally easy to find, and availability is not an issue for most riders.
Durability: Very Good Known for being highly durable, KTM bikes are tough and can withstand the abuse of hard enduro. They have a solid track record for long-lasting performance, though maintenance is key.

2. KTM 300 EXC TBI (2024-2025)

Price: High The TBI (Throttle Body Injection) models are expected to carry a similar price tag to the TPI models due to the new technology and increased performance. Expect a higher upfront cost, but it may offer better reliability and ease of tuning.
Performance: Excellent The TBI system is designed to be even more precise and reliable in extreme conditions, especially at high altitudes and in harsh environments. This model promises smoother performance and fewer tuning issues compared to carbureted bikes.

3. Sherco 300 SE

Price: Moderate to High Sherco tends to be slightly more affordable compared to KTM. However, for hard enduro, you’ll still be looking at a premium price for the 300 SE.
Performance: Excellent The Sherco 300 SE offers incredible power delivery, similar to the KTM 300, but it has a different feel and handling style. The Sherco bikes are known for their precision and balanced handling, making them a favorite for technical riders.
Part Availability: Good Sherco's dealer network and parts availability are not as extensive as KTM's, especially in certain regions. You might face delays in getting partsor need to rely on third-party distributors.
Durability: Very Good Sherco bikes are built to last and are known for their toughness, though some riders report needing a little more attention to maintenance than KTM due to certain parts' wear. Regularly check to the connection of the regulator rectifier to ensure there is no corrosion, otherwise you could be left on the track with a flat battery.

4. Rieju 300 MR

Price: Moderate Rieju bikes are generally more affordable compared to KTM and Sherco. The 300 MR offers great value for money, especially for riders on a budget.
Performance: Good to Very Good The Rieju 300 MR is a newer competitor and while it doesn't have the raw power or refinement of a KTM or Beta, it still delivers solid performance. The bike is decent in terms of power delivery, but it might lack some of the fine-tuning and the punch that top-tier bikes offer.
Part Availability: Fair to Good While Rieju is growing in popularity, their parts availability is more limited than KTM, Beta, or Sherco. In some regions, it might take longer to find parts, and their aftermarket support isn't as strong.
Durability: Good Rieju bikes are durable but may not quite match the endurance of higher-end brands like KTM or Beta. Regular maintenance is key, and some components may wear quicker under heavy use.

5. Beta 300 Racing version

Price: Moderate to High Beta is generally slightly less expensive than KTM but still comes in at a premium price point for hard enduro bikes.
Performance: Excellent The Beta 300 is a fantastic performer, particularly in hard enduro. It’s known for a great balance of power and handling, making it suitable for tough, technical riding. The engine offers strong low-end torque, which is great for slow-speed technical sections, and it has excellent suspension.
Part Availability: Good Beta’s parts availability is improving but isn’t quite as widespread as KTM’s. However, they are more readily available in key markets, and aftermarket parts are becoming easier to find.
Durability: Very Good Beta bikes are known for their rugged durability, especially in tough conditions. Many riders attest to the build quality, which is on par with KTM and Sherco, though some parts may need more attention after high-impact or extreme conditions.
