XTREME cr107, pros, cons, mods?

[honda_atc200es]

im thinking of getting an oil cooler kit for my pit bike, how effective is it, i dont want to spend big cash if im not going to get results. i am also looking at a big bore kit, some better suspension and a disc conversion kit for the rear, are these good or bad ideas, i want to make this bike more suited for trails, and i would prefer if the frame dosent snap of a big jump or something. does anyone have any advice about these bikes ( alot of my questions were answered by redrider ak) should i spend my 600 on a pitbike and build it up for trails, or should i look around or save money for a dirt bike or quad

Where are you going to stick said oil cooler? There's nowhere to place it on one of those little minibikes, everything is either motor or gas tank.

i wasnt sure myself, but the oil coolers are made by xtreme, i think i read in the description they are samll enough to be mounted underneath the frame
