NGage TORQX Gold Star-Ring Chain & Sprocket Kit for Royal Enfield Himalayan 450 / 452 – 520 116L, 15T/47T | 520X2-116LHIM450

NGage TORQX Gold Series Star-Ring Chain & Sprocket Kit for Royal Enfield Himalayan 450

Upgrade or replace the complete final-drive set on your Royal Enfield Himalayan 450 with the NGage TORQX Gold Series Chain Sprocket Combo Kit – Part No. 520X2-116LHIM450.

This is the NGage application specifically listed for the new Himalayan 450 / 452cc Sherpa-platform motorcycle. The kit uses a 520-size, 116-link Star-Ring sealed chain with a 15-tooth front sprocket and 47-tooth rear sprocket, together with a complete NGage chain-care package.

For buyers searching by common market terms, this kit may also be found as a Himalayan 452 chain kit, Sherpa 450 chain sprocket kit, New Himalayan 450 chain set or 15T/47T 116-link Himalayan chain kit. The motorcycle's official model name remains Royal Enfield Himalayan 450; 452 refers to its approximate engine displacement.

Exact Kit Specification

Designed Specifically for the Himalayan 450

The Himalayan 450 uses a different chain-and-sprocket configuration from the older Himalayan 411 and from the Guerrilla 450. NGage assigns this motorcycle its own exact kit code: 520X2-116LHIM450.

The key fitment specification is:

• 520 chain
• 116 links
• 15T front sprocket
• 47T rear sprocket

These numbers matter. Do not substitute the older Himalayan 411 kit or the Guerrilla 450 kit simply because the motorcycles share the Royal Enfield name or, in the case of Guerrilla 450, the Sherpa engine family.

Star-Ring Sealed Chain Technology

The TORQX 520X2 uses a Star-Ring sealing profile. Unlike a conventional circular O-Ring, the shaped Star-Ring seal is designed to retain lubricant around the chain's internal pin-and-bush working surfaces while helping reduce lubricant loss and contamination.

NGage positions the Star-Ring design around improved lubricant sealing, reduced chain elongation and longer service life when the chain is correctly installed, adjusted, cleaned and lubricated.

CHOHO 520X2 Technical Chain Specification

The TORQX catalogue identifies CHOHO Chains as the manufacturer of the Thai-made chain system. CHOHO's technical specification for the 520X2 Star sealing ring chain lists:

• Pitch: 15.875 mm
• Plate thickness: 2.0 / 2.0 mm
• Sleeve / bush: Seamless
• Minimum listed tensile-strength specification: 34 kN
• Manufacturer application class: 200–500 cc motorcycles

The Himalayan 450's 452cc engine falls within that manufacturer-listed displacement class.

Brass-Coated Gold Chain

The TORQX Gold Series uses a distinctive brass-coated / gold-finish chain. Apart from its premium appearance, the sealed-chain construction and surface treatment are intended for demanding everyday, touring and adventure-motorcycle use.

Super-Hardened Sprocket Teeth

NGage promotes the supplied front and rear sprockets with super-hardened teeth to improve resistance to tooth wear under repeated acceleration, engine braking, highway riding, touring and mixed-terrain use.

Special ED-Coated Sprockets

The TORQX sprockets use a special ED coating intended to improve surface durability and corrosion resistance.

Why Replace the Chain and Sprockets Together?

A new chain running on badly worn sprockets can wear prematurely, while new sprockets used with an elongated or damaged chain can also suffer accelerated wear. Replacing the chain, front sprocket and rear sprocket as one matched set gives the new drivetrain components the best chance to wear evenly.

When Should You Replace the Himalayan 450 Chain Kit?

Inspect the final-drive set if you notice:

• Repeated need for chain adjustment
• Excessive chain elongation or stretch
• Stiff or seized chain links
• Uneven tight and loose spots
• Chain slap or abnormal drivetrain noise
• Jerky low-speed power delivery caused by worn drivetrain components
• Hooked, sharp or visibly worn sprocket teeth
• Heavy rust or corrosion
• Damaged seals, plates or rollers

Installation Note

Professional installation is strongly recommended. The motorcycle drive chain and sprockets are safety-critical drivetrain components.

• Replace the chain, front sprocket and rear sprocket together.
• Use the correct chain joining / riveting method specified for the supplied chain.
• Correctly align the rear wheel.
• Set chain slack according to the Royal Enfield owner's manual for the exact motorcycle.
• Correctly secure front sprocket, rear sprocket, axle and related hardware.
• Rotate the rear wheel and check chain tension through the complete chain length.
• Verify free movement and correct installation before riding.

Chain Maintenance

• Inspect the chain regularly for wear or physical damage.
• Maintain correct chain tension and rear-wheel alignment.
• Clean the chain before lubrication and let it dry fully.
• Lubricate regularly and after wet, muddy or dusty rides.
• Do not use steam, petrol, gasoline, thinner, benzene, kerosene or similar aggressive solvents on the sealed chain.
• Replace the chain and sprockets together when worn.
