Capacity is spec'ed at 4.2 US gallons. Reserve is 0.8 US gallons.
I hit the end of the main around 130 miles. If I refuel immediately, it's usually 3.2 gallons to fill. 40mpg.
So if I was able to run the tank completely dry, it would be 160 miles. To get 200 miles from the 4.1 gal tank would require close to 50mpg. I suppose it's possible, but I've never seen it on my T. Farthest I've gone is about 150 (I chickened out).
When I refill, I top it all the way to the bottom of the front edge of the filler neck while holding the bike upright.
