According to the Suzuki Burgman Street 125EX (EA23M / UB125) Official Owner’s Manual Maintenance Specifications, the 2023–Present Suzuki Burgman Street 125EX (EA23M SEP-alpha) (chassis EA23M/UB125L) requires 0.65 L (0.69 US qt) of SAE 10W-30 (JASO MB, API SL or higher Low-Friction Scooter) engine oil for a drain-only change and 0.7 L (0.74 US qt) with filter service (16520-09J00 (Washable Oil Strainer Screen)). Standard solo cold tire pressure is 200 kPa / 2.00 bar / 29 PSI front (90/90-12 54J) and 230 kPa / 2.30 bar / 33 PSI rear (100/80-12 56J), paired with 1× NGK MR6F / CPR6EA-9 spark plug(s) and a FTZ6V / YTX5L-BS battery.
Drain only: 0.65 L (0.69 US qt)
R 230 kPa (2.30 bar)
Est. Range: ~289 km (180 mi)

4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
DO NOT CONFUSE PLATFORMS: The old Spanish-built liquid-cooled Burgman 125 maxi-scooter (UH125, 1.2 L oil, 16510-05240 paper filter, 159 kg) is completely unrelated to the modern air-cooled Burgman Street 125EX (EA23M, 0.65 L oil, mesh screen only, 12-inch wheels, 112 kg)!
Oil & Clutch Mechanical Engineering Note
Equipped with a dry centrifugal CVT and EASS auto stop-start, this air-cooled SEP-alpha scooter specifies low-friction SAE 10W-30 JASO MB oil—and takes ONLY 650 ml (0.65 L) on a drain! Measure strictly with a graduated cup so you never overfill.
Garage Wrenching Gotchas
- There is no disposable paper oil filter on the EA23M—only a cleanable 16520-09J00 mesh strainer screen. Because the 650 ml oil bath is tiny and air-cooled, halve intervals to 2,000–2,500 km in urban delivery use.
- While early non-EX Asian Burgman Street variants ran a 10-inch rear wheel, the 125EX upgraded to a 12-inch rear wheel (100/80-12)—verify 12-inch sizing before ordering rear tires.
5. Frequently Asked Questions (FAQ)
What are the exact engine oil and final gear oil volumes for the Burgman Street 125EX?
Engine oil refill is 650 ml (0.65 L) on a standard drain (~700 ml with strainer cleaning), and final reduction gear oil takes ~50 ml filled up to the side check-bolt hole.
What makes the Burgman Street 125EX stand out among urban 125 scooters?
Its brushless silent starter restarts whisper-quietly from idle-stop, while its flat step-through floorboard carries groceries or parcels that center-tunnel scooters cannot.
What cold tire pressures are specified for the Burgman Street 125EX?
Cold inflation is 200 kPa (29 PSI) front and 230 kPa (33 PSI) rear solo, rising to 250 kPa (36 PSI) rear with a passenger.
