the seal might be leaking very less amount of oil since you bought it but it is visible now because of the mud splashes and dust. get it changed under warranty. nothing to worry about
one more thing, the oil is coming out from different places, did you push the bike hard on original oil? change the oil as soon as you get this work done. and dont go for complicated oils at high prices which are not meant for these bikes. if you want to go for a good oil which you can use for long time, use liqui moly 20w50
