anyone done/do it? bike in question is a 2020 husqvarna fs450.. i finally fabbed up a belly pan from an acerbis skid plate and a bunch of fiberglass and i’m thinking of doing a some big track racing with it next round. track config is 2.2 miles and not any super long straights (umc east), but that’s on a sport bike.. i’m sure they’ll feel long on a dirtbike. i’d be in the production 500 class and the moto3 class.. so i’d be racing against ninja 400’s and the like. anyone done this? i’m going to one up the front sprocket, but almost wondering if i need to two down the rear.. i won’t have any track time prior to race day to test gearing. if anything it’ll be some fun shits and giggles. i just hope i’m not bouncing off the rev limiter the whole day.
