Correct. I have TPMS and they use BAR unit only. It’s not too difficult to program the brain to accept and understand BAR readings! I use the rough guide of 1 BAR = 15psi. It’s actually 14.5 but that’s too much math on a motorcycle!!
Very handy accessory to have, intriguing to see the pressure go up as the tyres warm up. Towards the end of today’s ride I was intrigued with the rear monitor displaying 1.9 BAR as I pulled into our driveway - sure enough, an inch long nail had pierced the rubber. Groan.
