Genuine Royal Enfield rocker-cover bolt for the 650 Twin engine family. Exact current service part number: 575248/D.

Quantity supplied: 1 bolt. Four bolts are used for a complete rocker-cover set, so order four only when replacing the full set.

Verified Motorcycle Fitment

• Royal Enfield Interceptor 650 / INT 650
• Royal Enfield Continental GT 650
• Royal Enfield Super Meteor 650
• Royal Enfield Shotgun 650
• Royal Enfield Bear 650
• Royal Enfield Classic 650

Fitment is confirmed against the exact 575248/D service number. Because production changes and market specifications can vary, compare the packet number and confirm by VIN/chassis number when the motorcycle has non-standard engine parts or uncertain service history.

Verified Product Details

What This Part Does

This fastener secures the rocker cover at the top of the Royal Enfield 650 Twin engine. Correct rocker-cover clamping helps the cover and its sealing components sit evenly. A damaged, rounded, corroded, stretched or incorrect bolt can make correct assembly difficult and should be assessed before the cover is refitted.

What Is Included

• 1 × genuine Royal Enfield rocker-cover bolt, 575248/D

What Is Not Included

• Other three rocker-cover bolts required for a complete four-bolt set
• Rocker cover / cylinder-head cover
• Rocker-cover gasket
• Sealing washer, rubber grommet or isolator unless physically supplied in the sealed package
• Valvetrain parts, sealant, tools or fitting labour

Photographs and the sealed packet should be checked before installation. This listing is specifically for the bolt and does not promise separately catalogued sealing parts.

Current Revision and Supersession

575248/D is the current verified replacement. Earlier genuine revisions 575248/B and 575248/C are both shown as superseded by 575248/D. If the removed bolt or an older parts book shows /B or /C, use the current /D number when ordering.

Why Exact Part-Number Matching Matters

A rocker-cover bolt is not selected only by visible length or head shape. The shoulder, threaded section and seating arrangement must suit the cover and seal system. Do not substitute a general hardware-store bolt or a visually similar fastener. Match 575248/D or obtain an official VIN-specific supersession confirmation.

Before Ordering

1. Confirm the motorcycle is one of the verified Royal Enfield 650 models listed above.
2. Match the required service number to 575248/D, 575248/C or 575248/B.
3. Confirm that the required item is the rocker-cover bolt—not a cover, gasket or sealing grommet.
4. Count the quantity needed: this product supplies one bolt; a complete set uses four.
5. If uncertain, check the VIN/chassis number with an authorised parts catalogue or qualified Royal Enfield technician.

When Replacement May Be Appropriate

• Bolt head is rounded or tool engagement is damaged
• Threads are worn, crossed, stripped or contaminated
• Bolt is bent, corroded or visibly damaged
• Incorrect non-standard hardware was previously installed
• A technician has specified bolt renewal during rocker-cover service

Installation Guidance

Work only on a cool engine and keep dirt out of the exposed cylinder-head area. Inspect the cover, gasket, sealing elements and threaded holes before assembly. Position the cover without forcing it, start each fastener by hand and tighten progressively in the sequence and to the torque specified in the correct Royal Enfield workshop manual. Over-tightening can damage the cover, seal or cylinder-head threads; uneven tightening can prevent uniform sealing.

Professional installation is recommended. This listing intentionally does not publish an unverified torque figure because the correct specification must come from the workshop information for the exact motorcycle and assembly.

Post-Installation Checks

• All four fasteners are present, correctly seated and tightened to specification
• Rocker cover sits evenly without visible distortion
• Gasket and sealing elements are correctly located and not pinched
• No oil seepage appears after the engine is run and rechecked
• No tools, rags or loose parts remain near the cylinder head

Material, Size and Torque Note

Reliable manufacturer-published material grade, dimensions, thread specification and tightening torque were not found in the verified product records used for this listing. Those values are therefore not guessed. Identify the part by its genuine number, verified motorcycle application and assembly position.
