MR8C-9N

Essential for providing the best possible spark to ensure optimal combustion of the air-fuel mixture in the engine cylinders while helping to dissipate the heat from the explosion of this mixture, motorcycle spark plugs should be replaced every +/- 10,000 kilometers, at regular intervals.
Their replacement may be necessary earlier if your motorcycle engine is not running properly.

A worn spark plug can cause ignition, combustion, and pre-ignition problems, increase fuel consumption, and reduce the power of the motorcycle...

There are 2 types of spark plugs: hot plugs and cold plugs. They are distinguished based on their thermal dissipation index, coded by a number on the plug.

Hot plugs have a low thermal dissipation index (low number), perfect for road riding.
Cold plugs have a high thermal dissipation index (high number), perfect for sport riding.

Thus, the performance of your motorcycle depends on them, both in terms of starting, engine efficiency, and fuel consumption.

NGK, one of the market leaders, produces the most performant and technologically adapted spark plugs for modern engines.
