Might think about the smaller tank like found on the Roadster, if long didtance trips are not an issue, but that wont be much weight loss.
FYI, 6.6 lbs per gallon...4.5 gal on the Custom, 3.3 gal on Roadster, keep the tank. The Sporty is just that, made for spirited riding, meaning it is rather minimalist (fewer options, less weight (600 lbs), 1200cc/74cu in, and so "less expensive"), but higher up to not scrape hard parts, so it is more "top" heavy feeling when stock, and invites heavy mods...:newsmile093:
I am a wee bit short at 5' 6" w/ 29 inseam and went for the larger tank, seat (another 1 1/2" less), lowered the bike w/fork & progressive shock mods another 1 1/2" and feels significantly less top heavy, even at parking lot speeds.
I am refitting the mid riding position brackets & pegs for riding in gravel or sand when two-up; otherwise I use the passenger pegs for rough/sport riding. BTW, if you lower your bike with all of the above mods, adjust the preload on the shocks 2nd notch (Solo) and 3rd notch (w/ Co-Rider)
Forward controls and highway pegs are nice for long rides stretched out, but in your case you might try the lowering approach I did at both ends and practice-practice-practice. My UJM Katana was also much more top heavy than the Sporty and higher off the ground to boot...you will adapt very quickly, just ride...it gets better
