According to the Kawasaki ER-6n (2006–2016) Official Owner’s Manual Maintenance Specifications, the 2006–2016 Kawasaki ER-6n (chassis ER650A/ER650C/ER650E) requires 1.6 L (1.69 US qt) of SAE 10W-40 (JASO MA2, API SG/SJ/SL) engine oil for a drain-only change and 1.8 L (1.90 US qt) with filter service (16097-0008 / HF303). Standard solo cold tire pressure is 225 kPa / 2.25 bar / 33 PSI front (120/70 ZR17 M/C 58W) and 250 kPa / 2.50 bar / 36 PSI rear (160/60 ZR17 M/C 69W), paired with 2× NGK CR9EIA-9 spark plug(s) and a YTZ10S / YTX12-BS battery.
Drain only: 1.6 L (1.69 US qt)
R 250 kPa (2.50 bar)
Est. Range: ~336 km (209 mi)
