Not just 125...Any bike in general. However not all parts, and even those that do, usually don't add all that much. However, if you have lots of money and can find good parts you can add about a third of the current power to your bike.

Yes try a company called UFO they make after market plastics for about everything.
Larger sprokets (at the cost of wear on your chain and engine) and aftermarket exhausts will help but only by 6 - 8 %. Its only a 125 engine after all.
