Yamaha Vino 125 - Master Maintenance & Torque Guide

The Yamaha Vino 125 shares its 780 x 21.5mm CVT belt and 45 Nm primary sheave nut spec directly with the Yamaha Cygnus 125 and, notably, with the Zuma 125 covered elsewhere in this catalog. This consistency across Yamaha's 125cc CVT platform means belt service knowledge transfers cleanly between models, provided the torque discipline stays consistent regardless of body style.

Field note: The air-cooled Vino 125 engine uses an oil strainer screen (OEM # 54P-E3411-00). Always check final drive gear oil levels (130 ml drain / 140 ml total volume) at every oil interval.

Dimensions780 x 21.5 mm
Torque SpecPrimary sheave nut: 45 Nm (33 lbf·ft)
Cross-CompatibilityYamaha Cygnus 125
Field note: Under-torquing this 45 Nm sheave nut is a frequent cause of a subtle top-end rattle that develops gradually over a few hundred miles as the nut slowly loosens — by the time the noise is loud enough to notice, taper wear on the crankshaft has often already begun. Always re-torque and inspect after the first 200-300 miles following any belt service.

5PD-11635-002Piston Pin Clip (Circlip)Directional installation — see expert note below
Field note: On this 125cc single shared with the Yamaha Cygnus 125, the piston pin circlips must be installed with the opening gap oriented 90° to piston travel, never fore-or-aft. A backward clip compresses under load until it ejects into the crankcase, and the freed pin gouges the cylinder wall on the next stroke, destroying the bore. Use only new clips and confirm full seating by feel.

Field note: Yamaha's painted plastic panels become progressively brittle at the mounting tabs after roughly three years of continuous UV exposure. Never use an impact driver on body screws, and apply silicone grease (never petroleum-based) to rubber grommets before removal so panels flex free without cracking.
