KZ road race gear

Hi Guys,
Any sit-up KZ guys care to share a good starting gear for a road race track ?
Ran a 17/22 or 18/23 at TGPR with a CR125, but in the dark for a good starter gear on a TM KZ R2….
Cheers,
Bill

I also run a CR125 road/long circuit. I’m told a 19/21 is a good combo in a stock KZ that is running road circuit.
