Model-Year & Chassis Generation Notes
Lightweight European-styled retro commuter; Fiddle III 125i ran a simple air-cooled 2V CBS setup before 2021+ Fiddle 125 added liquid-cooled ABS options.
Oil & Clutch Mechanical Engineering Note
Holding just 0.8 L of oil in its forced-air crankcase, change SAE 10W-40 JASO MB every 2,000–2,500 km and clean the left-bottom strainer screen.
