The NGage B8RII-8 Double Iridium Spark Plug is a precision ignition component developed for select Suzuki motorcycles, including the Suzuki V-Strom 250 and Suzuki Burgman 125. Manufactured in Japan, this spark plug is part of NGage’s Double Iridium series and is specified for use in both BS4 and BS6 compliant motorcycles, as stated by the manufacturer.

This listing focuses exclusively on its application for Suzuki motorcycles where the B8RII-8 spark plug specification is listed by NGage in its official compatibility chart. It is intended as a direct replacement spark plug for these motorcycles, without modification.

Designed for Suzuki Motorcycles

NGage specifies the B8RII-8 spark plug for a defined group of Suzuki motorcycles that share compatible ignition system requirements.

The following Suzuki models are listed by NGage for use with the B8RII-8 spark plug:

• Suzuki V-Strom 250

• Suzuki Burgman 125

These motorcycles represent two distinct riding formats within Suzuki’s lineup: a lightweight adventure-touring platform and a fuel-injected urban scooter platform. Despite differences in displacement and application, NGage lists the same B8RII-8 spark plug specification for both models, indicating alignment with their respective ignition system design and operating parameters.

For both motorcycles, the B8RII-8 is intended to function as a like-for-like replacement for the factory-specified spark plug type. It is not positioned as a tuning component or a modification-driven upgrade, but as a specification-correct ignition part for routine service or replacement.

Double Iridium Spark Plug Construction

NGage classifies the B8RII-8 as a Double Iridium spark plug, meaning iridium material is used on both the center electrode and the ground electrode.

Iridium is used in modern spark plug construction due to its high melting point and resistance to electrode erosion during repeated ignition cycles. This construction approach is commonly applied in motorcycles with high-energy ignition systems and tightly controlled combustion environments.

The double-iridium configuration is intended to maintain consistent electrode geometry over extended operating periods under normal riding conditions. NGage does not publish electrode dimensions, spark-gap values, heat-range explanations, or service-interval figures for this model.

BS4 and BS6 Compatibility

NGage specifies that the B8RII-8 spark plug is compatible with both BS4 and BS6 vehicles. This makes it suitable for use across production years that fall before and after the BS6 emission-standard transition, provided the motorcycle is included in the compatibility list.

For the Suzuki V-Strom 250 and Suzuki Burgman 125, this ensures suitability across emission-compliant variants without requiring a change in spark plug specification.

No emission-reduction, fuel-efficiency, or tuning claims are made for this product.

Manufacturing Origin

The B8RII-8 spark plug is manufactured in Japan, as stated by NGage.

NGage does not publish further information regarding production processes, certifications, or testing standards for this model. The country of manufacture is provided here as factual product information only.

Intended Use

The NGage B8RII-8 is intended for routine replacement during scheduled maintenance or spark-plug service intervals recommended by Suzuki. It is suitable for everyday road use on the Suzuki V-Strom 250 and Suzuki Burgman 125 within standard operating conditions.

This spark plug is not positioned by NGage as a racing-only, track-specific, or specialized tuning component.

Fitment Accuracy

Correct spark plug selection is critical for engine operation and long-term reliability.

The B8RII-8 should be installed only on motorcycles listed in the compatibility section below. Use on non-listed motorcycles is not recommended.
