Field note: On the eSP short block shared with the PCX 150, the piston pin circlips must be fitted with their opening gap 90° to piston travel, never fore-or-aft. A backward clip compresses under inertial load on every stroke until it walks out of its groove and 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 before closing the case.

Field note: This platform's painted plastic body 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 can flex free without cracking a brittle tab.
