Towing a trailer to Sturgis is the easiest way to bring ten days of gear without burying your bike in luggage. The rules do not change because it is rally week: every HitchDoc motorcycle hitch is rated for a maximum of 40 pounds of tongue weight, tongue weight stays at or under 10% of the loaded trailer, and you never load past your bike’s gross vehicle weight rating. In practice that means a loaded trailer around 400 pounds is your sensible ceiling, and lighter is better. Use a hitch made for your exact bike, a trailer built for motorcycles, wiring that runs real lights, and ride the trip out there more conservatively than you would solo. Do that and the trailer will be the easiest part of the trip.
Key Takeaways
- Every HitchDoc motorcycle hitch is rated for 40 pounds of tongue weight, no more than 10% of the loaded trailer, which makes about 400 pounds loaded a sensible ceiling.
- Pack heavy items low and centered over the trailer axle, then weigh the trailer and the tongue separately before you leave.
- Cross the safety chains under the tongue, run trailer and rear bike tires at maximum allowable pressure, and confirm your lights work.
- Towing speed limits and lane rules can differ from solo riding, and in a group you ride at the back.
- A hitch made for your exact bike bolts on clean and nearly disappears when the tongue is out.
Why bring a trailer to the rally at all?
The Sturgis Motorcycle Rally runs August 7 through 16 this year, and ten days is a long time to live out of saddlebags. Camping gear, rain gear, cold morning layers for the Black Hills, tools, and everything you buy once you get there. Riders solve this three ways: ship gear ahead, strap the bike into a mountain of luggage, or pull a small cargo trailer.
The trailer wins for most touring riders. The bike stays agile because the weight rides on the trailer’s axle instead of stacked over your rear wheel, you keep your passenger seat, and you are not paying to ship a duffel bag both directions. This company has a soft spot for that answer. The Mohns family built their first motorcycle hitch in the family farm shop and introduced it at the 50th Anniversary Sturgis Rally. Hauling gear to Sturgis is not a side use for a HitchDoc hitch. It is the original job.
How much can you tow to Sturgis?
Three numbers govern the whole trip, and they are the same numbers whether you ride a Road Glide, a Gold Wing, or a Chieftain.
First, your bike’s gross vehicle weight rating. That is the most the motorcycle is built to carry, including you, your passenger, your gear, and the tongue weight of the trailer. Adding a hitch does not raise it.
Second, tongue weight. Every HitchDoc motorcycle hitch is rated for a maximum of 40 pounds of tongue weight. That number is not about the strength of the steel. It is about how much load you can hang off the back of a motorcycle before it starts steering like something else.
Third, the 10% rule. Tongue weight should never exceed 10% of the gross trailer weight, contents and cargo included. Run the easy math backward from the 40 pound ceiling and a loaded trailer around 400 pounds is your sensible limit. A typical motorcycle cargo trailer leaves you a couple hundred pounds of actual gear inside that number, which is plenty for a ten day trip if you don’t try to bring the whole garage.
If you want the full rundown on the numbers and why they matter, our guide on towing a trailer with a motorcycle goes deeper. The short version: stay inside the limits and towing is a proven, safe way to travel. Ignore them and no hitch will save the handling.
How do you pack a motorcycle trailer for ten days?
Load the heavy stuff first, low and centered over the trailer axle. Tent, tools, and anything dense goes in the middle of the box. Light bulky items like sleeping bags and clothes fill in around them. Weight behind the axle lifts tongue weight off the hitch and invites sway. Weight stacked high raises the trailer’s center of gravity. Low and centered is the whole trick.
Then weigh it. After the trailer is loaded, weigh the trailer and the tongue separately. A bathroom scale under the coupler works for the tongue. You are checking two things: the loaded trailer is inside your target, and the tongue is carrying roughly 10% of it without crossing 40 pounds. Five minutes in the driveway beats guessing at 75 mph in a South Dakota crosswind.
One piece of hard earned rally advice: leave room. Nobody comes home from Sturgis with less than they brought. Pack the trailer to about three quarters full going out, or the t-shirts, parts, and campsite finds ride home bungeed to the lid.
What should you check before you leave?
The night before you roll out, run the same checklist we put on every hitch page.
Cross the safety chains under the tongue of the trailer, so if the coupler ever lets go the tongue lands in the chains instead of on the pavement. Leave just enough slack to turn, and never let the chains drag.
Air up. Trailer tires go to their maximum allowable pressure unless the trailer manufacturer says otherwise, and your motorcycle’s rear tire goes to the maximum on its sidewall. Check both again partway through the trip. A soft trailer tire is where sway starts.
Confirm the lights. Your trailer needs working brake lights and turn signals, wired through a harness matched to your bike. Some bikes need an isolator or converter so the trailer lights do not overload the motorcycle’s wiring. Sort this out at home, not in a parts store parking lot in Rapid City.
Finally, if you have never towed before, do not make the interstate on-ramp your first practice run. Hook up a week early and put some local miles on the rig, loaded, so wide turns and longer braking are old news before the trip starts.
What changes when you are towing a trailer to Sturgis?
The ride out is interstate miles, wind, and eventually the Black Hills, and the trailer changes your habits in a few specific ways.
Speed and lanes first. Posted speed limits for vehicles pulling trailers can be lower than the regular limit, and many states keep trailers out of the left lane by law. Know the rules for the states you cross, hold a steady conservative pace, and let the sport bikes have the passing lane.
Give yourself distance. Acceleration and braking both take longer with a loaded trailer. Follow farther back, plan passes you could cancel, and slow down earlier for corners than you would solo. The Black Hills roads that make the trip worth it, the tight stuff around Deadwood and the canyon runs, deserve extra respect with 400 pounds behind you.
Ride at the back of the group. Rally week means group riding, and the rule on our hitch instructions is the rule to follow: when riding in a group with a trailer, take the rear position. Your longer braking distance stays behind everyone else’s rear wheel.
And if the trailer ever sways or bounces, slow down gradually and stop. Do not stab the brakes and do not try to steer through it. Figure out what is wrong, usually load placement or a soft tire, before you tow another mile.
Why a HitchDoc hitch belongs on this trip
A trip like this is exactly what HitchDoc hitches were built for, literally. The first one went to the 50th Anniversary Sturgis Rally, and the company has been making bike-specific hitches from American steel in Minnesota ever since. Each hitch is made for a specific make, model, and year, so it bolts to your bike the way the factory would have done it, and every one carries the same clear 40 pound tongue weight rating so you know exactly where the line is. Pick the receiver style and the tongue pulls with one pin when the rally is over, leaving almost nothing to see on the bike. Find yours in the motorcycle hitch lineup, covering Harley-Davidson, Honda, Indian, Kawasaki, Suzuki, Triumph, Victory, and Yamaha, or start with the model guides for Harley-Davidson and the Honda Gold Wing.
Frequently Asked Questions
How big a trailer can I tow to Sturgis?
Work backward from your hitch and your bike. With a 40 pound maximum tongue weight and the 10% rule, a loaded trailer around 400 pounds is the sensible ceiling, and your bike’s gross vehicle weight rating still has to cover you, your passenger, and the tongue weight. A light cargo trailer built for motorcycles fits those numbers. An automotive utility trailer does not.
Do I need special wiring for the trailer?
You need a harness that runs the trailer’s brake lights and turn signals from your bike, and some models need an isolator or converter so the added lights do not overload the factory wiring. It varies by bike, so if you are not sure what yours takes, ask before you order.
Can I ride in a group with a trailer?
Yes, and thousands of riders do it every rally. The one firm rule is position: ride at the rear of the group, because your braking and acceleration distances are longer than everyone else’s. Leave extra following distance even back there.
Can I take the hitch off after the rally?
With a receiver style hitch you do not have to. Pull one pin and the tongue slides out, and what stays on the bike is small and finished in chrome or black powder coat. Most riders leave it on year round and forget it is there until the next trip.
Ten days at the rally goes better when your gear rides behind you instead of on top of you. Find the hitch built for your exact bike in the motorcycle hitch lineup, or call (800) 446-8222 and we will help you spec the whole setup before you roll west.
