hey, mso's are good.
the 140s is cheapest, if u say ur from miniriders they'll do u a very good deal. 1,200 i think it is... it has a dnm shock and heavy duty very very stong front forks...140cc engine that will pull along a house etc. lol
i'd contact them, or maylands, who has the 140xr for like 1195 i think...
cheers
