OS SPEED B21 ONGARO EDITION Combo with exhaust

Davide Ongaro, who won the last IFMAR 1/8 Nitro Off-Road World Championship with an LRP / OS MAX engine, signed a contract with OS SPEED at the end of 2021 for at least 2022.

Thanks to this cooperation, the BESTIE called "OS SPEED B21 ONGARO EDITION" was born, which was modified according to his suggestions, comments, but mainly experience from tracks from all over the world.

Based on the latest OFF ROAD engine OS SPEED B2104, the crankshaft was changed to the shape of an extra-square engine and a crankshaft with one tungsten weight, made especially for this engine, was used to suit the driving style of DAVIDE ONGARA and similar pilots. The inner head liner also has a specially designed combustion chamber and its effect realizes a smooth feel and more powerful upper engine speeds. In addition, the cooling head uses a standard round type and the laser marking with the original ONGARO logo creates a racing atmosphere.
The carburetor uses new 5.8mm and 6.3mm black anodized aluminum diffusers so that everyone can set up a "Big Race Engine" and meet the requirements of every demanding pilot.
