I have a 310 pv in my atc250r with all the mods to make it work good, its almost too much bike for the chassis and thats with a +1 swinger. It should stomp 450's in a quad chassis.

My sparks 270 can walk all over a stock 450. not sure how a modded 450 would compare.

I was Just Curious on how a 310 kit wil run with those 450's.
I am Anxious to take mine to the dunes and run it with those thumpers. Here is what MY 250 looks Like

i have a 310 pn my 250r and i will out run my wlash crf and 06 450 up top, its an excellant choice for mx but not enough bottom for xc.

I have an ESR 310 w/the 7 porting.Its right there with modded 450s.Win some, lose some, depends whose on the 450.My next one will have the 9 porting,so it should be a little better on top.

[Eddiesanders250]

i think you meen the 11 porting?

[Eddiesanders250]

sorry never mind it is the 9 porting
