OEM SPECIFICATION SUMMARY
According to the Suzuki DR-Z4S (2025) (2025–Present) Official Owner’s Manual Maintenance Specifications, the 2025–Present Suzuki DR-Z4S (2025) (chassis DR-Z4S) requires 1.7 L (1.80 US qt) of SAE 10W-40 (JASO MA2, API SJ/SL/SM) engine oil for a drain-only change and 1.9 L (2.01 US qt) with filter service (16510-29F00 / HF139). Standard solo cold tire pressure is 150 kPa / 1.50 bar / 22 PSI front (80/100-21 M/C 51P) and 150 kPa / 1.50 bar / 22 PSI rear (120/80-18 M/C 62P), paired with 2× NGK MR8E-9 spark plug(s) and a YTX7L-BS / YTX9-BS battery.
