I used my SPX for the first time today in the Intermediate 17.5 Class i have only been racing On Road for maybe 3-4 months. I won the TQ and the A-Main by more than a lap.
I think the time to bump up to Sportman is near.
We run on a preped asphalt track.
Here is my setup:
Sorex 32s (it was cool and overcast all day)
SPX on Profile 7
Fantom Ion2 17.5 (Stock Timming)
IB Intellect 5000mAh 40C 2S Batteries.
