Is that stainless steel? Looks pretty nice!

So you now have 7.7 + 3 = 10.7 gallons which yields about 428 to 450 miles of fuel autonomy (maybe a tad more depending on how you are riding)... Which leads to the question: Are you planning to join one of those iron butt competitions?

What's the weight recommendation for that location?
Looks good! Where are you plumbing into the standard tank?

I'm sure the luggage rack weight suggestion by Honda has been surpassed by almost every rider that has used the luggage rack. I would guess the 3 gallons of gas and tank weight about 30 pounds. My 3.2 gal. aux. tank hangs behind the rear wheel taking the place of the rear fender on my 1100. No problems in years of use.

haven't thought about any iron butt ride other than maybe a 1500 but the three guys I ride with the most have a fuel, when done we will all carry about the same amount of fuel

the tank is made of aluminum
my friend has the same setup on his ST 1300 and has not had an issue with the aux tank and fuel

The ST1300 manual states the weight limit for the aft rack in 20 pounds. On the 1100, the support has been known to crack when overloaded for an extended time....metal fatigue. That's the reason I asked the question.

I've run with more than 20 lbs. on that rack for many, many miles with no issue.

Wow looking sweet. Wonder if it could be powder coated black to match the bike. I went from a 2 gallon tank on my cx to the 7 gallons on the st. An thought that already was huge. I looked at these a few times for the cx. Never got around to actually seeing one. Cant wait to return your seat now so I can check it out.

On the 1300 the rack is plastic. No metal fatigue. ;)

There is a support under the rack that it mounts to with four bolts. That support is bolted to the rear frame. This is the part to be concerned about. I don't know what material the support is since I don't have a 1300 I can't go out and look. On the 1100 the corresponding part is metal. Plastic fatigues (over-stresses, if you will) as well as metal.

Ok, so how do you get the gas into the tank? I see the line but here's the real question: Are you filling the main tanks after they go down about 4 gal or hook it straight up? The rear tank is above the main tanks. That doesn't look like a good idea. Just asking.

Most aux fuel cells are gravity feed into the main tank, hence the high mount position. Once the main tank gets low enough, you open the manual valve from the aux tank and let the fuel flow into the main tank. I have one sitting in the garage from my old Triumph Daytona 1200. At 5 gallons capacity, it's too big to use on my ST per the IBA rules for rallying. IBA limits total onboard capacity to 11 gallons.

The tail dragger tanks have an electric pump to push the fuel up and into the main tank.
