montys and some onzas have seats which are very small but kinda comphy depending on how long you sit down on it lol, most others dont have seats because it is extra waight and it is so you can get more tucking on the bike when you sidehop or back wheel, it also helps for better balance hope i helped, you can sit on boosters depending on how big you are in height. sometimes it hurts you knees but not a lot
