Davide Ongaro, the IFMAR 1/8th engine off-road car world champion, has signed a works driver contract with O.S.SPEED starting in 2021. The "O.S.SPEED B21 ONGARO EDITION" has been created with modifications to match his feeling! Based on the latest off-road engine, the crankshaft was modified with a new counterwaves shape and a single tungsten weight to suit his driving style.

The inner head also has a specially designed combustion chamber, and the synergistic effect of these two elements results in a smooth feeling and high RPM growth. The outer head is a standard round type, and the laser marking of ONGARO's logo creates a racy atmosphere. The carburetor also features a new size of ø5.8mm/ø6.3mm black anodized aluminum reducer to match his requirements for an "engine that can win big races. We also have a combo set that includes the TB02 EFRA2089 tuned silencer and /MB01-75 (75mm) manifold exhaust system.
