This. Unfortunately,alloy forks are common these days because they are light and cheap.

Yes,but you'll prolly spend at least $125 on the fork,plus installation if you have a shop put it on. A steel fork will add weight,but be about half the price. Wider,lower pressure tires will also help,as will better grips or a carbon bar.
