I am not in the least mechanically inclined and I have less suspension knowledgein my whole body that some of the guys here do in their pinky fingers.

I do however know that sportbikes from the factory are set up for a 160-180 pound person. I on the other hand weigh 250lbs and am in sore need of an aftermarket shock.

You will need an aftermarket shock and not just a stiffer spring to set up the bike properly.

Ohlins are wicked expensive, but Penske offers a more cost effective alternative and should probably meet your needs unless you are a very advanced rider.
