B6ES - long reach / town and city use / for a standard engine.


B7ES - long reach / town and city use / for a standard engine.

B8ES - long reach / local and distance use / for a standard or midly tuned engine. 

B9ES - long reach / competition or distance travelling use / for a tuned engine.

Spark plugs with a 'BR' denomination have a built-in resistance and are designed for use with delicate electronic equipment (such as SIP rev counter / speedo units). 

Spark plugs with a 'HS' denomination are SHORT reach versions (usually utilised for early pre-S1 Lambretta models manufactured between 1947-'57).

Lambretta models that use a SHORT REACH spark plug are: A + B + C / LC + D / LD + E /F + Lambrettino 48.

Lambretta models that use a LONG REACH spark plug are: S1 + S2 + S3 + GP / DL + J (all versions) + Lui Vega Cometa + Serveta.

NGK copper core spark plugs deliver increased heat dissipation for more reliable starts and reduced risk of overheating.


Colder spark plugs are suitable for racing cylinders and use over long distances. In this context, the sound thermal output of heat to the cylinder head takes place, there is a risk of sooting, however.


Hotter spark plugs are used in sport and standard cylinders. The reach their operating temperature quickly but can also overheat.

Most spark plugs for scooters have a M14x1.25 SW 20.8 thread and are either long thread (19mm) or short thread (12.7mm).


Please note: putting a long thread spark plug in a short thread cylinder head will damage the piston.


Copper spark plugs are the most popular spark plugs on the market and are a useful tool in every day scooter life. Rapid operating temperature, constant performance, optimal reaction during changing driving conditions, for example town driving, and last but not least, fuel savings are their advantage.


The copper core of the middle electrode conducts the heat well and protects against thermal overload. Nickel-chrome-alloy protects the copper core against corrosion and guarantees high level protection against wear and tear and spark erosion.
