John, I always ran my ST4S at 32F/36R unless on track when I dropped to 30 F/R. I always found the ST4S would feel a bit 'vague' on the steering with higher pressures. When we were racing the TZ250 that ran at 36psi F/R-HOT-straight out of the warmers. Those pressures are on slicks and with a bike weighing 103kg don't forget. John Growing old-disgracefully! |
