Hero Genuine Gear Shift Selector Fork R/L for Xpulse 200, Xtreme 160R, Xtreme 200, Xpulse 200T, Hunk, Achiever, Ignitor & Impulse | Single Gearbox Fork | 24211KRM840S

Hero Genuine Gear Shift Selector Fork R/L – 24211KRM840S

Replace a bent, worn, scored or damaged internal gearbox selector fork with the Hero Genuine Fork, R/L, Gear Shift, part number 24211KRM840S. This precision internal transmission component is used in the gear-shift drum assembly of compatible Hero Xpulse, Xtreme, Hunk, Achiever, Ignitor and Impulse motorcycles.

The gear-selector fork follows the shift-drum track and moves the corresponding transmission gear or sliding component along its shaft when the rider changes gear. Excessive fork wear, bending, heat marks or damaged contact faces can contribute to incomplete gear engagement, gear jumping out under load, difficulty selecting a gear or abnormal internal gearbox movement.

This listing is for one R/L gear-shift fork only. Compatible gearbox diagrams commonly require two pieces of 24211-KRM-840 because the same fork design is used in two selector positions. The separate centre gear-shift fork carries another part number and is not included.

Compatibility boundary: Similar motorcycle names do not guarantee the same gearbox internals. No automatic compatibility is claimed for Xpulse 210, Xtreme 125R, Karizma XMR, scooters or another model unless its parts catalogue specifies 24211-KRM-840.

Fitment Note / Return Prevention Note

Before ordering, match the complete Hero part number 24211KRM840S or catalogue number 24211-KRM-840 with the motorcycle’s chassis/VIN-based gearbox catalogue.

Confirm all of the following:

• Exact motorcycle model and production generation
• Engine and gearbox version
• Required selector-fork position
• Part number stamped, invoiced or identified in the gearbox diagram
• Fork guide width and contact-face condition
• Selector-fork shaft and shift-drum arrangement
• Total quantity required after dismantling and inspection

Quantity clarification: Hero’s retail pack contains one fork. Many compatible assemblies list a required quantity of two for 24211-KRM-840. Order two only when the mechanic confirms that both matching R/L forks need replacement or the repair requires both pieces.

Do not confuse this part with:

• 24212-series — centre gear-shift fork
• 24241-KRM-840 — gear-shift fork shaft A
• 24242-KRM-840 — gear-shift fork shaft B
• 24301-series — gear-shift drum
• 24610-series — complete external/internal gear-shift spindle component
• 24700-series — external foot-operated gear-change pedal assembly

A motorcycle that is difficult to shift or jumps out of gear may also have worn gear engagement dogs, damaged transmission gears, a worn shift drum, bent fork shafts, selector-spindle damage, weak return springs, incorrect clutch adjustment or internal bearing damage. Replacing the fork alone will not repair an unrelated gearbox fault.

What You Will Receive

• 1 × Hero Genuine Fork, R/L, Gear Shift
• Part number: 24211KRM840S
• One manufacturer-packed internal gearbox selector fork

Not included: second R/L fork, centre selector fork, selector-fork shafts, shift drum, gears, transmission shafts, circlips, washers, bearings, gear-shift spindle, clutch components, crankcase gasket, engine oil or installation labour.

Technical Details

Installation Note

Gearbox repair requires complete engine and transmission dismantling and should be performed only by a trained motorcycle engine technician.

During inspection and installation:

• Compare the removed fork with the exact replacement part number
• Inspect both matching R/L forks and the separate centre fork
• Measure fork contact surfaces and guide width against service limits
• Inspect the shift-drum grooves for scoring, wear or impact damage
• Check both selector-fork shafts for bending and surface damage
• Inspect gear engagement dogs, sliding gears and transmission shafts
• Replace damaged circlips, washers, bearings and gaskets as required
• Maintain the exact fork positions, direction and gearbox assembly order
• Use the prescribed engine oil and model-specific tightening specifications

After reassembly, confirm that every gear selects positively with the engine safely supported. Check clutch adjustment, neutral selection, abnormal noise and oil leakage before a controlled road test.

Buyer-Focused FAQs

1. What is Hero part number 24211KRM840S?
It is a Hero Genuine internal R/L gear-shift selector fork used in compatible Hero motorcycle gearbox assemblies.

2. Is this an external gear lever?
No. This part is fitted inside the engine gearbox. The external foot-operated gear lever or pedal is a separate component.

3. How many forks are supplied?
One fork is supplied in the manufacturer pack.

4. Why does the gearbox catalogue show quantity two?
The same 24211-KRM-840 fork design is used in two R/L selector positions in many compatible gearboxes. The retail SKU still supplies one piece.

5. Should I order one or two pieces?
Order according to the gearbox inspection. Buy two only when both matching R/L forks need replacement or the mechanic has specified two pieces.

6. Is the centre gear-shift fork included?
No. The centre fork is a separate part, commonly listed under a 24212-series part number that can vary by model.

7. Does it fit Hero Xpulse 200?
Yes. Confirmed references include Xpulse 200 and Xpulse 200 FI May 2019, Xpulse 200 2V BSVI June 2020 and Xpulse 200 4V November 2024.

16. Can a worn selector fork cause the gear to jump out?
Yes, a bent or worn fork can contribute to incomplete gear engagement. Worn gear dogs, shift drum damage and other gearbox faults can produce the same symptom.

17. Can this part fix hard gear shifting?
Only when the selector fork is the confirmed cause. Clutch adjustment, external linkage, shift spindle, drum, shafts, gears and bearings must also be inspected.

18. Can this be installed without opening the engine?
No. This is an internal gearbox component and requires major engine/transmission dismantling.

19. Is professional installation necessary?
Yes. Incorrect fork position or gearbox assembly can cause shifting failure and serious internal engine damage.

20. How can I prevent ordering the wrong fork?
Match the complete SKU, exact motorcycle and generation, gearbox diagram, selector position, required quantity and chassis/VIN-based Hero catalogue.
