Parts Unlimited 2113 0217 Factory Activated AGM Battery YT4B BS Maintenance Free Fits DRZ50 DRZ70 TTR50E TTR90E TTR110E SR400 Vino 50

OVERVIEW

The Parts Unlimited 2113‑0217 Factory‑Activated AGM Battery delivers reliable starting power and stable voltage output for youth motocross platforms, entry‑level trail bikes, and vintage dual‑sport models. Constructed from sealed absorbent glass mat chemistry, this maintenance‑free component eliminates traditional acid handling while resisting vibration and terminal corrosion. Engineered as a direct replacement for the standard YT4B‑BS group, it mounts into motorcycle battery compartments without requiring adapter fabrication.

ENGINEERING & PERFORMANCE

This sealed power source utilizes high‑capacity active material matrices alongside glass‑mat separators to maintain consistent cranking performance across temperature swings and reduce self‑discharge during long storage periods. Anti‑sulfation compounds extend service life, while the pressure‑tested casing shields internal plates from impact shock and track abuse. The maintenance‑free design allows upright or inverted mounting stability and includes precise OEM dimensions for straightforward bolt‑in installation. Riders experience durable operation that matches original equipment clearances and electrical routing.

WHY RIDERS CHOOSE THIS

Off‑road enthusiasts select this replacement unit because the sealed AGM architecture removes fluid maintenance risks while delivering instant engine turnover in cold conditions. The reinforced, pressure‑tested casing dampens chassis vibration and prevents electrolyte leakage, which keeps electrical connections clean on muddy trails or beach rides. Because it retains its charge during dry storage and aligns precisely with factory battery trays, riders restore dependable ignition and charging curves without modifying mounting hardware. This bolt‑in simplicity ensures aging engines recover consistent performance through daily trail duty and seasonal rotation.
