Its compact size, durable construction, and precise spark delivery make it the preferred choice for motorcycle enthusiasts, scooter riders, and small engine owners who demand reliability and peak performance.

Key Features & Technical Specifications

• Model Code: CR8E (1275)
• Thread Size: M10 x 1.0 mm
• Heat Range: 16 mm (optimal for most street and sport bikes)
• Cathode Material: Copper core – ensures excellent heat dissipation and longevity
• Tip Diameter: Ø10 mm
• Pin Length: 19 mm (standard for most motorcycle engines)
• Material Composition: Nickel‑plated steel body with a copper core electrode and a ceramic insulator
• Compatibility: Engine types ranging from 125 cc to 250 cc, including Honda CBR125R, Kawasaki KLX250, Yamaha WR125, Suzuki SV650, Kymco 125 Quannon, and many more.

Design Excellence for Optimal Ignition

The NGK 1275 Spark Plug incorporates NGK’s proprietary “Cr8” technology. This design features a precisely engineered electrode gap and a high‑temperature ceramic insulator that together produce a clean, powerful spark even under demanding conditions such as high RPMs or heavy loads.

The copper core not only improves heat transfer but also enhances the plug’s resistance to wear, ensuring consistent performance over thousands of miles. The nickel plating protects against corrosion, while the robust steel body withstands the vibrations and stresses typical in motorcycle engines.

Wide Range of Applications

The versatility of the NGK 1275 Spark Plug is evident from its compatibility with a multitude of models across several manufacturers:

• Honda: CBR125R, CBR250RR, CB500F, and various scooter models.
• Kawasaki: KLX250, KFX400, ZXR600, and sport bikes up to 650 cc.
• Yamaha: WR125, YZF125R, MT-07, and many street‑legal scooters.
• Suzuki: SV650, GSX-R750, and the popular V-Strom series.
• Kymco: 125 Quannon, 300 Dink Street, and other commuter models.

Because of its standard size and heat range, it can also be used in small engines such as lawn mowers, generators, and outboard motors that require a 10 mm tip diameter spark plug.

Installation & Maintenance Guidelines

1. Preparation: Ensure the engine is cool. Remove any old spark plugs carefully to avoid damaging the cylinder head.
2. Threading: Use a torque wrench set to the manufacturer’s recommended value (typically between 12–15 Nm for most motorcycles). Over‑torque can damage the head; under‑torque may lead to poor combustion.
3. Gap Check: Verify the electrode gap with a spark plug gauge. The standard gap is usually 0.7–1.0 mm, but check your bike’s service manual for exact specifications.
4. Inspection: Inspect the insulator and electrode for cracks or wear before installation. Replace any damaged plugs immediately.
5. Cleaning: Keep the spark plug area free of oil, dirt, and carbon deposits to ensure a clean spark.

Regular inspection (every 10,000–15,000 km for most sport bikes) will keep your engine running smoothly. Replace plugs when you notice symptoms such as rough idling, misfires, or reduced fuel efficiency.

Performance Benefits

• Enhanced Combustion: The precise spark timing and clean ignition improve combustion efficiency, leading to better throttle response.
• Fuel Economy: A reliable spark reduces fuel consumption by ensuring complete fuel burn.
• Reduced Emissions: Efficient combustion also lowers harmful exhaust emissions.
• Longevity: The copper core and nickel plating extend the plug’s life, reducing maintenance frequency.
