There are a couple options. You could put highway bars/ engine guards on, like this, and then put pegs on them:
They are available from several aftermarket companies, or from Suzuki. Just do a google search, and remember that your S83 is the same as the Intruder 1400, so any bars that fit the 1400 will fit your S83.

They are available from MCEnterprises, with a variety of peg designs.
There are some other brands also, which are similar. Try a goodle search for 'highway pegs intruder 1400", as there are not many accessories that are listed specifically for the S83 even though they are the same.
