Keep a few things to keep in mind, todays machines do not have the raw low end tractor like grunt torque the old pre evo bikes had. Flywheel weight and stored energy isn't there anymore, don't give a damn what dyno sheet's show so you'll be on the clutch, gearbox and throttle more because of it. Very different set of riding skills you not be comfortable with off the bat, maneuvering and braking becomes a preplanned very deliberate exercise the more you have behind you. Beefy in the braking system or you'll know it quick.

 

I've towed trailers with my bikes before, including some really overloaded utility ones. Based on experience, I really don't recommend towing upwards of half a ton.

I strongly disagree with you about using the rear axle or swing arm pivot as a mounting point for the hitch. The frame makes a far superior mounting for a hitch.

Make the hitch strong, particularly for side to side thrusting. I made one once that was a bit too light and therefore wiggly side to side, that was very unpleasant. That hitch was immediately discarded.

I would not recommend trying to tow a bike where you'll be trying to lean the towed bike with your Fatboy. You'll likely never get it off the kickstand, and it will be vicious about tipping. Instead, I'd suggest a folding trailer or dedicated motorcycle carrying trailer. That will be much more stable.

Then there's brakes. Your bike's brakes will be fine for a typical little cargo trailer to carry your camping gear on. But towing the weight of a bike will push you hard, and could overwhelm your bikes brakes. I'd seriously consider a trailer with electric brakes for that. You may even have a legal need for that, depending on what your state thinks of a vehicle up on a trailer.

Noise can be a factor with a cargo trailer. Not only is the bike working harder to pull it, but it's reflecting the noise right back at you. A soft trailer won't be as loud in reflection as a hard faced trailer will be.

Tire pressure becomes an interesting game with a motorcycle cargo trailer. Mine weighed something like 40 lbs, so that trailer tires were ridiculously overkill. I ended up at something like 2 psi in them to get a ride that wasn't bouncing everywhere. Maybe something like 4-6 psi when loaded up fairly heavily.

I actually quit using my cargo trailer because I would habitually over pack for my needs, simply because I could.

Just some observations and experiences from my trailer towing.

 

Thank you for the input everyone.
As for the trailer, the trailer I want to make will be tiny, not much more than carrying maybe 50lbs, a full backpack.
Pulling another bike is probably just not a good idea, I guess ill have to go with getting my gf to pull a trailer on a truck when we get one.

 

You going to want more then just the bike at a track day of any kind, I would probably just rent a uhaul especially if it’s just occasionally while you get the bunny ears wet,

 

I think you are making a big mistake that can have serious consequences. I do not recommend this.

 

This is one of those deals where just because can, doesn't mean you should. Besides, you wouldn't be able to split lanes, Fran....;-)

 

Problem is that I dont drive cars/trucks. My gf doesn't either.
She's only interested in learning to drive so she can handle a truck on a homestead.
I'll probably have to ask a friend to come get me and my bike for a track day. Schedule something on the same day.
I have a friend who'd probably be down to do that, he loves track riding and helps people there.

I'm still gonna need a small trailer for camping, that's another thread.

 

That’s probably a good solution, a pop up sun shade, some chairs, even a grill and a cooler, for you and the pit crew. The bike needs tools and spares, plus your race gear packed and unfortunately racing mean breaking or worst, I had the tiniest inclosed cargo trailer behind my Jeep.

My friend has done it back in the day. i don't think I would, at least not with his set-up.
