Hi Shay,
The bike might have been lowered for a lady, or short legged rider.
The OEM 'dogbones' are not adjustable. There may be aftermarket ones on there, not real uncommon if the bike was owned by a short rider.
Maybe you can post a picture of them? Somebody may be able to tell you. If they're aftermarket 'lowering' links, you may be able to buy some used OEM ones somebody took off, pretty cheaply. There are also aftermarket ones that aren't real expensive.
I'd identify the dogbone, or links before you look for a solution.
If they are aftermarket links, you may be able to adjust them. There are other things you should do, adjust the forks in the clamps, for best and safe handling. Check here before you do anything. I'm no expert, but there's a lot of good help here. FWIW, a lot of bike shop mechanics don't know much, and pass on a lot of BS.
Tires, like said, a 'sport touring' type is your best bet. You should have some nice twisty roads near you, if you ever get into riding 'sporty'.
They'll work fine, and last longer than a 'sport' tire.
BT020, DUNLOP D220, and I think the current favorite is the Metzler Z6.
You're looking around $300, installed.......for a set...or more.
If in doubt about your tires, replace them. If the bike doesn't have a lot of miles on it, they could be pretty old. Even with no signs of weathering, tires older than 2-3 years can be suspect.
Check the manufactured date code on the sidewall, and use your sense.
It's your butt!
