I weigh considerably more than 225 and have no trouble dialing in stock suspension, it's a time consuming trial and error job but there's enough adjustability in any modern sportbike to cover it. Frankly most street riders simply don't have the ability to tax a modern sportbikes suspension, it's just a case of making continious small adjustments, checking results and so on.
Don't make massive changes to front and rear or you'll lose track of what you did and what works. Compression is what the bike does when you hit a bump, how do the forks absorb the impact, if they're to stiff they'll jack hammer, to soft they'll wallow. Same with the rear, too stiff and they'll slam your tailbone, too soft and the bike will mush. Try to get the compression damping to where the bike seems to absorb the bumps without upsetting the chassis. Rebound is how the bike stays in contact with the road, again too soft and the bike will feel like it's hobby horseing too stiff and the tires won't keep maximum contact and it'll feel like it's skipping or washing out.
Try to seperate what each end of the bike is doing and dial compression and rebound in or out to maintain as much a balance as you can. Make one or two adjustments to the forks then try it out, if that works leave it and ride it for awhile and try to judge the overall reaction. If the front feels planted work on the rear making small adjustments and try that for a while..it's total trial and error, race teams spend hours and hours on suspension settings for each track. On the street you want the best compromise set-up for the widest range of surfaces. You can do it, it just takes time and patience.
