Finally made the leap from a 1999 yz250 to a 2007 kx450f. I'm 5'7 pushing 5'8 (maybe on a good day) and weight about 165 lbs. I'd love to get the balls of my feet on the ground without sacrificing any performance if at all possible and am open to suggestions. I'm done racing at age 35, I might hit an open practice or two but for the most part I'm on trails, about 95% of the time and it would help to get more then just the tip toes down. Bike feels great only rode it once because its still freezing here, making it pretty tough to start and cold to ride. I'll probably go with a 48 rear sprocket as well for tight trails unless anyone thinks that's a terrible idea?
