What Size Trailer Do You Really Need for Two Dirt Bikes? A Definitive Guide

The ideal trailer size for hauling two dirt bikes typically ranges from a 5×8 utility trailer to a 6×12 enclosed trailer. However, the exact best size depends on factors like the bike size, hauling frequency, inclusion of gear, and desired level of security.

Understanding Your Dirt Bike Hauling Needs

Choosing the right trailer for transporting your dirt bikes is more than just finding something that fits. It’s about ensuring safety, ease of use, and protecting your investment. Several critical factors come into play when determining the ideal trailer size. Ignoring these considerations can lead to unsafe hauling practices, damaged bikes, and unnecessary stress. This guide will walk you through the essential considerations and provide practical recommendations to help you make the best decision.

Open Utility vs. Enclosed Trailer: Which is Right for You?

The first major decision is whether to opt for an open utility trailer or an enclosed trailer. Each has distinct advantages and disadvantages:

  • Open Utility Trailers: These are generally less expensive, easier to maneuver, and offer greater visibility while towing. However, they leave your dirt bikes exposed to the elements and potential theft. Securing your bikes adequately is crucial when using an open trailer.

  • Enclosed Trailers: These provide superior protection from weather, road debris, and theft. They also offer additional storage space for gear, tools, and other essentials. The downside is that enclosed trailers are more expensive, heavier, and can be more challenging to maneuver.

Key Factors Influencing Trailer Size

Several elements directly influence the appropriate trailer dimensions:

  • Dirt Bike Size: The dimensions of your dirt bikes, including length, width, and handlebar width, are paramount. Larger bikes, like adult-sized motocross or enduro bikes, will require more space than smaller youth models. Consider measuring your bikes to get accurate dimensions.

  • Hauling Frequency: If you only haul your bikes occasionally, a smaller, more manageable trailer might suffice. However, frequent hauling warrants investing in a more robust and spacious option.

  • Gear Storage: Do you need to transport helmets, riding gear, tools, fuel, and other accessories? If so, an enclosed trailer with ample storage space or a larger utility trailer with dedicated storage solutions is essential.

  • Towing Vehicle Capacity: Ensure your tow vehicle has the capacity to safely tow the trailer and its contents. Overloading your vehicle can be dangerous and illegal. Consult your vehicle’s owner’s manual for towing capacity specifications.

Recommended Trailer Sizes and Configurations

Based on typical dirt bike dimensions and hauling requirements, here are some recommended trailer sizes:

  • 5×8 Utility Trailer: This is often the minimum size for hauling two adult-sized dirt bikes. However, it may be a tight fit, and you’ll need to be strategic with placement and securing straps. It’s best suited for shorter trips and minimal gear.

  • 6×10 Utility Trailer: This offers a bit more breathing room and is a good compromise between size and maneuverability. It allows for easier loading and securing of the bikes and provides some space for basic gear.

  • 6×12 Utility Trailer: This is an excellent choice for those who frequently haul two dirt bikes and need room for gear. It offers ample space for loading, securing, and transporting bikes and accessories comfortably.

  • 6×10 Enclosed Trailer: This provides the security and weather protection of an enclosed trailer while remaining relatively manageable in size. It’s a good option for those who prioritize security and need some extra storage space.

  • 6×12 Enclosed Trailer: This is the ideal enclosed trailer size for two dirt bikes if you need maximum security, ample storage, and a comfortable hauling experience. It allows for easy loading and unloading, and you can even set up a mini workshop inside.

Securing Your Dirt Bikes

Properly securing your dirt bikes is crucial for safe transport, regardless of the trailer size. Invest in high-quality tie-down straps, wheel chocks, and a robust trailer locking system. Avoid using cheap or worn-out straps, as they can fail during transit. Aim for at least four tie-down points per bike – two on the handlebars and two on the frame or rear swingarm. Regularly inspect your straps for signs of wear and tear and replace them as needed.

Frequently Asked Questions (FAQs)

FAQ 1: Can I haul two dirt bikes in a 4×8 utility trailer?

Generally, a 4×8 utility trailer is too small to safely and comfortably haul two adult-sized dirt bikes. While one smaller youth dirt bike might fit, two larger bikes will likely overhang the sides, creating a hazardous situation. Prioritize safety and choose a larger trailer.

FAQ 2: What are the best types of tie-down straps for dirt bikes?

Ratchet straps are generally considered the best for securing dirt bikes due to their ability to tighten securely and maintain tension throughout the journey. Avoid using bungee cords, as they lack the necessary strength and reliability. Also, consider using soft loops around the handlebars to prevent damage to the grips and controls.

FAQ 3: Should I use wheel chocks when hauling dirt bikes?

Yes, absolutely! Wheel chocks provide additional stability and prevent the bikes from shifting during transit. They significantly reduce stress on the tie-down straps and minimize the risk of damage to your bikes.

FAQ 4: How much weight can a typical 5×8 utility trailer handle?

The weight capacity of a 5×8 utility trailer varies depending on the specific model and its construction. However, most have a gross vehicle weight rating (GVWR) ranging from 2,000 to 3,000 pounds. Be sure to check the GVWR of your trailer and never exceed it. A typical dirt bike weighs between 200 and 250 pounds.

FAQ 5: How do I prevent my dirt bikes from rubbing against each other during transport?

Use padded dividers or foam padding between the bikes to prevent them from rubbing and causing scratches or damage. You can also strategically position the bikes so that handlebars and footpegs are staggered to minimize contact points.

FAQ 6: What are the legal requirements for trailer lights and safety chains?

Most jurisdictions require trailers to have functioning taillights, brake lights, and turn signals. Safety chains are also mandatory, providing a secondary connection between the trailer and the tow vehicle in case the primary hitch fails. Always check your local regulations before hauling a trailer.

FAQ 7: Can I use a trailer without brakes for hauling dirt bikes?

Trailers without brakes are typically suitable for lighter loads. For hauling two dirt bikes, especially with gear, a trailer with brakes is highly recommended, particularly if your tow vehicle is smaller or if you’re traveling on hilly terrain. Brakes significantly improve stopping power and overall safety.

FAQ 8: How do I calculate the total weight I’m hauling?

Add the weight of your trailer (tare weight) to the weight of your dirt bikes and all gear. This total weight must be less than the GVWR of your trailer and the towing capacity of your vehicle.

FAQ 9: What’s the best way to load dirt bikes onto a trailer?

Using a loading ramp is the safest and easiest way to load dirt bikes onto a trailer. Ensure the ramp is securely attached to the trailer and that the angle is not too steep. Have someone spot you while loading and unloading to prevent accidents.

FAQ 10: How often should I inspect my trailer tires?

Inspect your trailer tires before each trip for signs of wear and tear, such as cracks, bulges, or low tread depth. Also, check the tire pressure and inflate them to the recommended pressure. Maintaining proper tire pressure is crucial for safe towing.

FAQ 11: What type of hitch is best for towing a trailer with dirt bikes?

The best type of hitch depends on the weight of your trailer and the towing capacity of your vehicle. A Class III hitch is typically sufficient for hauling two dirt bikes with a utility trailer. However, for heavier enclosed trailers, a Class IV hitch may be required. Consult your vehicle’s owner’s manual for hitch recommendations.

FAQ 12: What is the impact of trailer size on fuel economy?

Larger and heavier trailers will generally result in lower fuel economy. The added weight and wind resistance increase the load on your engine, leading to increased fuel consumption. Consider this factor when choosing a trailer size, especially if you frequently travel long distances.
