Kick Starter Shaft Assembly for Royal Enfield 4-Speed Models | 111152/A | Bullet 350/500, Deluxe, Machismo, Campus, Electra 4S, Lightning 535

If your Royal Enfield’s kick-start has started slipping, skipping, jamming, or feels “free” with poor engagement, the Kick Starter Shaft Assembly (Part No. 111152/A) is one of the most common and correct fixes for 4-speed gearbox motorcycles. This is the genuine Royal Enfield kick starter shaft assembly used in the 4-speed foot-starter system (not a universal shaft). 

Unlike many aftermarket shafts that develop play early (leading to repeat kick-back, damaged pawl/ratchet parts, and inconsistent engagement), an OEM-spec shaft restores proper alignment and engagement geometry—critical for safety and gearbox longevity. It’s an ideal replacement during a gearbox end-cover overhaul or when you’re changing related wear parts like pawl/plunger/spring kits and O-rings. 

Important: this part is for 4-speed models—customers frequently order the wrong part for Thunderbird / 5-speed Electra, so please match your gearbox type before purchase.

Installation / Fitment Notes (Practical)

• Confirm your motorcycle is 4-speed gearbox before ordering (major return reason). 

• During replacement, inspect associated pawl/plunger/spring and O-rings; worn parts can mimic shaft failure. 

• If your kick lever “bites” inconsistently, check the stop plate + pawl mechanism for wear along with the shaft. 

FAQs 

Q1. Is 111152/A original (OEM) Royal Enfield?
Yes—111152/A is listed as a genuine Royal Enfield kick starter shaft assembly in dealer catalogues. 

Q2. Will this fit my Thunderbird / Electra 5-speed?
No. This part is for 4-speed gearbox fitments, and multiple sellers explicitly exclude Thunderbird / 5-speed applications. 

Q3. My kick slips—do I need only the shaft?
Often the shaft is the fix, but slipping can also come from the pawl/plunger/spring or stop plate wear. Best practice is to inspect those parts during installation. 

Q4. Is this the “foot starter spindle” / “kicker shaft” people ask for?
Yes—customers commonly refer to this as kicker shaft / foot starter spindle/shaft for 4-speed Bullets. 

Q5. Do you need my chassis number to confirm?
Recommended. If you share your model + year + gearbox type (4-speed/5-speed), we can help reduce ordering errors.
