Beschrijving

This is the OS Speed B2103 Type S engine. This 3-port long-stroke engine offers a high torque at mid-low range with a sweet delivery and low consumption.

The B2103 Type S comes with a low–profile cooling head to provide better drivability and also vertical fins on the top to improve heat dissipation.
