I'm curious to see some experience with modded 250R's and aftermarket swing arms. I run a stock swing arm and love its handling but man is it a handful from 1-4 when hill racing. Any of you big bore guys still running the stock arm?

 

if I only had one ATC then I'd stay stock or maybe +2 at the most...but since I have over a dozen I can afford to run the longer ones. if you spend all your times out on the dunes I'd say go with a longer one up to +6, but if you also ride in the woods or tight spots that long one will suck.
