We have had 10 years of automotive powertrain experience. By drawing on our innovative EFI technology, ¡§be gentle to the earth¡¨ is not a slogan but also proven to our engine to the backbone. CECTEK has created an extensive line of the powerful, reliable and clean recreation engines on the market.
These liquid-cooled single-cylinder, 4-stroke engines are designed specifically for recreation and power sports applications. They cover a range between 250 and 500 cc and come with EFI fuel system and intergraded gearboxes - with semi-automatic, manual or with CVTs (continuous variable transmissions).

Features
¡@
lPowerful
These single-cylinder engines are available with electronic fuel injection (EFI) or carburetor in order to meet all applications.
Inlet and exhaust port have been developed with assistance of a computerized flow bench and CECTEK airflow expertise. The four valves are designed for best airflow of the induction system. Valve train components have been lightened to allow faster valve opening. Combustion is therefore homogeneous allowing best thermal efficiency at any rev.
¡@
lReliability
These engines designed specifically for recreation and power sport applications. The exceptionally reliable originate in the firm and solid structure and high efficiency of cooling & lubrication system.
¡@
lCompact
Low engine height and intergraded drive system which combine with crankcase and sub-transmission. These engines are easy to fit for various frames to reduce developing time and cost.
¡@
lGreen
Comply with the newest emission norm such as EURO III, EPA2006.
