The optimal trailer size for hauling two Harley-Davidson motorcycles generally ranges from 12 to 16 feet long and 6 to 7 feet wide. This allows for sufficient space for secure loading, proper weight distribution, and safe transport, considering both the physical dimensions and the weight of the bikes.
Understanding Trailer Size Requirements
Choosing the right trailer for transporting two Harley-Davidson motorcycles is crucial for ensuring their safety, your safety, and the integrity of your towing vehicle. Beyond the initial length and width, several factors influence the ideal trailer size, demanding careful consideration. We’ll delve into these considerations to empower you to make an informed decision.
Key Factors Influencing Trailer Size
-
Motorcycle Dimensions and Weight: The specific models of Harley-Davidson motorcycles you intend to transport are paramount. A pair of Sportsters will require less space than two fully dressed touring bikes like Road Glides or Electra Glides. Consider the overall length, width (including handlebar width), and height of each motorcycle. Crucially, understand the curb weight of each bike. This combined weight directly impacts the trailer’s required Gross Vehicle Weight Rating (GVWR).
-
Trailer Type: Enclosed trailers offer superior protection from the elements and theft but require more interior space for maneuvering and loading. Open trailers are more affordable and offer better visibility during loading but leave the bikes exposed. Tilt trailers simplify loading, while ramp trailers offer more control. Each type presents different space considerations.
-
Loading Configuration: Will you load the bikes side-by-side or staggered? Staggering, where one bike is slightly ahead of the other, can save space but requires careful securing. Side-by-side loading offers easier access for strapping down but necessitates a wider trailer.
-
Personal Preferences and Tow Vehicle Capacity: Some riders prefer a larger trailer for easier maneuverability within the trailer and additional storage space for gear and tools. However, your tow vehicle’s towing capacity is the ultimate limiting factor. Never exceed your vehicle’s specified towing capacity, which is usually found in your owner’s manual or on a sticker in the driver’s side door jamb.
Minimum and Recommended Trailer Sizes
As mentioned earlier, a 12-16 foot long and 6-7 foot wide trailer is generally adequate for two Harleys. However, consider the following:
-
Minimum Size (12-foot Length): Suitable for two smaller Harleys like Sportsters or similar-sized bikes. This size can feel cramped, and securing the bikes might be more challenging.
-
Recommended Size (14-foot Length): Offers a good balance between maneuverability and sufficient space for most Harley models. Provides more room for securing straps and adjusting the bikes’ positioning.
-
Optimal Size (16-foot Length): Provides ample space for larger touring bikes and allows for greater flexibility in loading and securing. Offers the most comfortable and secure transport experience.
-
Width Considerations: A 6-foot wide trailer might feel tight, especially if loading side-by-side. A 7-foot wide trailer provides significantly more room for maneuvering and securing the bikes.
Selecting the Right Trailer: A Step-by-Step Guide
-
Measure Your Bikes: Accurately measure the length, width (handlebar to handlebar), and height of both motorcycles you intend to transport.
-
Calculate Total Weight: Determine the curb weight of each motorcycle and add them together. This is the minimum weight your trailer must be able to handle.
-
Assess Your Tow Vehicle’s Capacity: Consult your vehicle’s owner’s manual or door jamb sticker to determine its maximum towing capacity.
-
Consider Trailer Type: Decide whether an open or enclosed trailer best suits your needs based on budget, weather protection requirements, and security concerns.
-
Determine Loading Configuration: Visualize how you plan to load the bikes (side-by-side or staggered) to determine the necessary width and length.
-
Factor in Extra Space: Add extra space for securing straps, tools, and gear. Err on the side of caution and choose a slightly larger trailer if you’re unsure.
-
Check Trailer GVWR: Ensure the trailer’s Gross Vehicle Weight Rating (GVWR), which is the maximum permissible weight of the trailer and its cargo, exceeds the combined weight of your motorcycles and any other items you plan to carry.
-
Investigate Trailer Features: Consider features like built-in wheel chocks, D-rings for securing straps, and a sturdy ramp or tilt mechanism for easy loading.
Ensuring Safe Transport
Safe transport goes beyond just choosing the right size trailer. It involves secure loading, proper weight distribution, and regular maintenance.
Secure Loading and Tie-Down Techniques
-
Use Quality Straps: Invest in high-quality ratchet straps or cam buckle straps specifically designed for motorcycle transport.
-
Secure to Frame or Sturdy Points: Attach straps to the motorcycle’s frame, triple tree, or other strong points. Avoid attaching straps to handlebars or other easily damaged components.
-
Compress Suspension: Compress the motorcycle’s suspension slightly when tightening the straps. This helps prevent the bike from bouncing during transit.
-
Cross-Tie Strategy: Use a cross-tie strategy, where straps pull the motorcycle diagonally forward and outward, to provide maximum stability.
-
Double-Check Everything: Before hitting the road, double-check all straps and ensure they are securely fastened.
Weight Distribution
-
Center the Load: Position the motorcycles so that their weight is evenly distributed across the trailer’s axles. A slightly forward position is generally preferable.
-
Avoid Overloading: Never exceed the trailer’s GVWR. Overloading can lead to trailer damage, tire blowouts, and loss of control.
Trailer Maintenance
-
Regular Inspections: Regularly inspect the trailer’s tires, lights, brakes, and hitch.
-
Tire Pressure: Maintain proper tire pressure according to the manufacturer’s recommendations.
-
Wheel Bearings: Grease the wheel bearings regularly to ensure smooth operation.
Frequently Asked Questions (FAQs)
FAQ 1: Can I get away with a smaller trailer if I’m only transporting my bikes short distances?
While a smaller trailer might be acceptable for short distances, compromising on trailer size significantly increases the risk of damage to your motorcycles and the potential for accidents. Even for short trips, invest in a properly sized trailer that allows for secure loading and weight distribution.
FAQ 2: What is the difference between an open and enclosed trailer for two Harleys?
Open trailers are generally more affordable, lighter, and offer better visibility during loading. However, they leave the bikes exposed to the elements and potential theft. Enclosed trailers provide superior protection from weather, road debris, and theft, but are more expensive and heavier.
FAQ 3: What is the Gross Vehicle Weight Rating (GVWR) and why is it important?
The GVWR is the maximum permissible weight of the trailer and its cargo, including the motorcycles, straps, and any other items you’re carrying. Exceeding the GVWR is extremely dangerous and can lead to trailer damage, tire blowouts, and loss of control.
