XS is a smaller version of the Freerider / Its because you get it with an RST fork instead of Manitou and the bike will be lower.
Freerider STreet will not be in the US until late summer I think.
It possible to buy extended waranty directly from Kuberg for 199 USD and then you are covered for 9 months!
I think that is fairly decent considering the industry standard. :D
