-1 ; +1 sprockets

I have a opportunity to purchase a vortex -1 up front +1 in the rear for a nice price. My question is this a good set-up I know most either go down 1 in the front only or -1;+2. Just looking for some input on the -1 +1 setup. Thanks

i would do it but for me as a rider i like the normal stock set up i just got the rk 520 conversion not the sure the ratio on the gear teeth but it is so nice man it seems like i got more bottom end all i can say is depends on what kind of rider you are and where you ride.

Thanks for the input man

i did down one up two 520 and i love it.the front end comes up with barely any throttle,takes off like a bat out of hell too
