Dad’s old Honda AX-1 30 years old now engine still runs perfect has probably over 10 million miles since we ride a lot

I only modified the cosmetics the air filter and gearing you know like chains and sprocket

Top speed 130-160kmph

City traffic 20 kmpl

Highway 25+ kmpl

This bike still pulls a lot, the engine is very good just requires a bit more maintenance than new ones

Honda XL then AX-1/ NX250 then XR and lastly CRF
