An on-raod sports bike like the cagiva mito 125 or the kawasaki zx250. It will be mainly used short distance around town and occasionly longer journeys.

The 4 stroke 250 would be more powerful and also more fuel efficient. Although a 2 stroke engine fires twice as often it can only use a part of the stroke before the ports in the cylinder are open. Using ports also makes it less efficient that a 4 stroke with valves because some of the fuel/air charge goes straight through the cylinder and out of the exhaust port when it's running below the power band, above the power band the engine can't completely clear the exhaust from the cylinder. Two stroke engines also wear faster because of their inferior lubrication and the ports in the cylinders.

on road or off road?
a 2 stroke 125 has got the acceleration factor with it as a four stroke 250 you will find you'll have to "wind" it up a bit more to get a bit more out of it, despite it being 125cc's more it will not rev as high. personally i prefer 2 strokes because there way more fun, and if they go pop bit less of a ball ache to repair than a 4.. (cam chain, valves etc,,)

the 2 stroke wud prolly leave the 4 stroke on accleration,then by 45-50mph the 4 stroke wud come around an spank dat 2 stroke's ***. so where do u want that power,bottom end(2 stroke) top end (4 stroke). id suggest the 4 stroke due to less maintainance and rebulids, preferably the xr250
