hi guys looking to upgrade the brakes on my k4 750 track bike.
looking at the 2020 r1 callipers as i dont really want to fork out on HEL or Brembo at the moment, does anyone know what spacer size i will need? or will they bolt straight on? many thanks

If you have stock size 298mm brake discs then you would have to machine down the calipers. Brembo M4 calipers (not the Suzuki M4 "Brembo") + spacers would be easier.
