FAQs 

Q1 (Fitment): How do I confirm this cap fits my bike?
Check your bike is J-Series 350 (Hunter/Meteor/Classic Reborn/Bullet 350) and match by part number RAF00222/C. If unsure, take a clear photo of the lower cross tube hole and measure the opening (commonly ~32mm for this cap).

Q2 (Fitment): Is this the same on all Hunter/Meteor/Classic/Bullet 350 variants?
It’s shown on multiple J-Series frame partsbooks for those models; however, always confirm by part number + location (lower cross tube) because nearby frame plugs can look similar.

Q3 (Comparison): Why buy OEM (genuine) vs a generic rubber plug?
Generic plugs often vary in diameter, lip depth, and material hardness, leading to loose fit or early cracking. The genuine cap is designed for the OE frame opening and is typically the safest choice for proper sealing and long service life.

Q4 (Installation): How is it installed? Do I need tools?
It’s a press-fit cap. Clean the hole area, align the cap, and press evenly by hand. Avoid hammering; if it feels too tight/loose, stop and re-check you’re using the correct cap for the correct hole.

Q5 (Symptoms): What problems does replacing this solve?
Missing/damaged caps can allow mud/water ingress, causing grime buildup and corrosion in/around the cross tube area—especially with frequent rain rides or pressure washing.

Q6 (Returns-prevention): What should I send you to confirm before dispatch?
Send (1) your bike model + year, (2) a photo of the exact hole location (lower cross tube), and (3) a ruler/scale measurement of the hole diameter. This avoids ordering the wrong frame cap.
