Received 2 tanks for my talon and my father-in-law's talon. FIL will install both. He is almost finished with his after many interruptions.
A few installation things to note so far:
1. The retainer ring on the factory tank is TIGHT and a little difficult to remove. But going back into the Trailtank is easy.
2. The one tank (almost) installed so far does not sit low enough for the mounting tabs to sit on the mounting surfaces. I asked Trailtank about this and they said on the 2 seat model, the tanks are made with a bulge on the bottom that causes this. Trailtank says to push the tank down to start screws then cinch down. Once filled with gas, Trailtank says the tank plastic will relax. We shall see.
3. The Trailtank slid into place much easier than the OEM tank was to remove!
Overall, I'll be much happier with gas in the tank than carrying externally. Rotopax are an option but definitely not cheap either. Looking forward to trying out these tanks on a ride.
