We’re still open, and monitoring the situation. At times we won’t be able to answer the phone or get your order out the same day. The best email address to get us on is sales@dellorto.co.uk. Thanks for your patience!

We are still open but we are limiting the amount of staff in the office so some are working from home

** We are not open for personal callers **

We can currently take orders and ship the same or next day.

We’ll update if this changes.

The spark plugs for motorcycles and scooters have to endure extreme conditions voltages in excess of 30,000 volts, temperatures above 1000° and chemically corrosive environments, with very high pressures involved . The range offered by Bosch is extensive and appropriate to working on two wheels, and the application is simplified thanks to the electrode gap preset at the factory.

In the race, a motor runs for more than 80% at full throttle position and, therefore, the spark plugs  are specially designed to meet the specific demands that result from this condition.

The use everyday instead involves continuous goodwill , stop and go driving in traffic and even long journeys. The Bosch spark plug is designed precisely to respond adequately to all of these operating variables always ensuring:

– High resistance to wear

– Quick self-cleaning for safe ignitions

– Protection of the engine and the catalytic converter

– Immediate Starts

With these adaptors it is possible to use aircooled type 3 manifolds on the waterboxer engines, allowing the use of twin carburettors and hexbar or bellcrank type linkages.

The type 3 manifolds will allow the use of Weber ICT or IDF or Dellorto DRLA carburettors and give adequate clearance for short air filters.

Made exclusively for us to our design in the UK from aluminium.
