I ride a Yamaha 2010 Yz450 dirt bike used for motorcross only, I run a steel front sprocket and a stainless steel rear sprocket. Never affected me negatively . I used to go through two sets of aluminum sprockets a year on the dirtbike. Now with the stainless steel sprocket, three years and minimal wear. You have to replace your chain before you replace the sprockets. We are talking at 250 pound bike wet weight. That's essentially half of our street bike weight. I wouldn't get hung up on a little weight.
