Restore factory steering precision with the genuine Royal Enfield Steering Stem Assembly — Part No. 1100370 (latest supply suffix: 1100370/B). This is the complete OE stem that locates the lower triple clamp and bearings, keeping yokes aligned under braking and over rough roads. Because it’s OEM, the shaft taper, bearing lands, thread pitch and finish match your bike’s frame head perfectly—no shimming or re-machining—and it accepts the stock ball/roller bearings, dust seals and lock-nuts. Typical symptoms that call for a new stem include crash damage, bent yokes, notchy steering despite fresh bearings, or persistent pull/wobble after an impact.

Fitment confirmed for Classic 350 Reborn (J-Series, 2021-on) and Bullet 350 J-Series (2023-on) across the official Royal Enfield parts portal and multiple authorised dealers listing 1100370/B specifically as “STEERING STEM ASSEMBLY.” This listing is for the stem assembly only; re-order bearings, races and seals by VIN if needed.

FAQs

Q1. Do I need bearings with this?
The stem ships as the assembly; head bearings/seals are separate. Replace them if pitted/notchy.

Q2. Will this fit the new Bullet 350?
Yes—dealers list 1100370/B for Bullet 350 (J-Series, BS6) as well as Classic 350 Reborn. 

Q3. How do I know my stem is bent?
Bars don’t align after fork/yoke replacement, the bike “pulls,” or you see uneven bearing wear even after fresh races.

Q4. Any torque specs?
Use the workshop manual values for the top nut and lock-nut; adjust bearing preload so the bars fall side-to-side smoothly with no play.
