That may be a little bit to much bike for you step it down to say a kx250. But if you like it then keep it. Just dont kill yourself. If your an experienced rider then it would be ok but if you were a new rider be careful
im 5ft 10in and weigh 135lbs i just traded an rm100 for a kx500 it packs a ton of power but im a newer rider and people are always sayin to not get a motorcross bike and thats what i got is the bike not right for me.
