Seat Lock Latch Assembly (Under-Seat Catch) for Royal Enfield Hunter 350 (J1, BS6/Euro5) – RAU00098/B

RAU00098/B is the genuine Royal Enfield seat lock latch assembly—the under-seat “catch” that grabs the lock pin and keeps your rider seat securely closed. If your Hunter 350 seat feels loose, pops open on bumps, or needs multiple tries to lock, this latch is one of the first parts to inspect and replace. OEM fitment matters here because the latch geometry and spring tension decide whether the seat locks cleanly and stays locked.

FAQs 

Q1 (Fitment): How do I confirm this latch fits my Hunter 350?
Check your RC/model: it must be Royal Enfield Hunter 350 (J1, 349cc). Then match your old latch’s shape + mounting holes with the product photos and confirm the part number RAU00098/B on invoice/label when available.

Q2 (Fitment): Does it fit Hunter 350 Metro / Retro / Rebel?
Hunter 350 variants share the same J1 platform; however, always confirm by existing latch photo and mounting because seat/lock hardware can change with model-year updates. Hunter fitment is confirmed; variant-level confirmation should be done by photo/VIN if unsure.

Q3 (Comparison): OEM vs aftermarket seat latch—why buy genuine?
Seat latches are tolerance-sensitive. OEM ensures correct alignment and spring action so the seat locks in one press. Aftermarket pieces often cause repeat “seat not locking” issues due to slight geometry mismatch.

Q4 (Installation): What’s needed to install it?
Basic tools (typically spanner/socket + screwdriver). Replace the latch in the same orientation, torque evenly, and test-lock the seat 5–10 times before riding. If the seat still won’t lock, inspect the lock pin/seat base for bending.

Q5 (Symptoms): What problems does this part solve?
Seat not locking, seat opening on bumps, excessive play/wobble in rider seat, latch not catching, or intermittent locking after washing/rain.

Q6 (Returns prevention): What should I send you before ordering if I’m unsure?
Share a clear photo of your existing latch (top + side) and your bike model/year. If you can, share last 6–8 digits of VIN or the part number from your old invoice. This avoids wrong orders.
