stock on all 06 models was 19/35
my 07 single a-arm was 19/35, i believe that all the newer 07's are the 19/32
I have had good success witht the 19/35 at certain tracks and I only change the front sprocket up to a 20 or 21 for more top end vs changing the rear to a smaller sprocet for top end.
I have even seen guys us 18/32 to get almost the same gear ratio as 19/35
I get them at Spacely's Sprockets lol
