OEM SPECIFICATION SUMMARY
According to the Suzuki DR-Z4SM (2025) (2025–Present) Official Owner’s Manual Maintenance Specifications, the 2025–Present Suzuki DR-Z4SM (2025) (chassis DR-Z4SM) 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 200 kPa / 2.00 bar / 29 PSI front (120/70 R17 M/C 58H) and 200 kPa / 2.00 bar / 29 PSI rear (140/70 R17 M/C 66H), paired with 2× NGK MR8E-9 spark plug(s) and a YTX7L-BS / YTX9-BS battery.
