OS SPEED B21 ADAM DRAKE 3 engine itself

And it's here, just before the World Cup 2022 comes a new, dangerous and as always perfect weapon !!!

DRAKE 3 is a LIMITED SERIES with stunning performance

ADAM DRAKE is a household name in the professional 1/8 OFF ROAD world. His racing achievements cannot even be counted, only the title of World Champion is missing from his collection. (but in Italy after the holidays he will have another option) Adam uses exclusively and only OS MAX engines in his MUGEN models. We are pleased to announce the release of the OS SPEED B21 ADAM DRAKE 3 with an impressive cooling head and aluminum replaceable diffusers in black.

The OS SPEED B21 ADAM DRAKE 3 engine is a redesigned and improved version 2 that impresses with high torque in the medium to high speed range with linear power development and low consumption. The crankcase, crankcase cover and carburetor have a redesigned new design. The DLC-coated crankshaft has two tungsten weights for perfect balance and maximum smoothness. OS SPEED B21 ADAM DRAKE 3 has a tall but lightweight cooling head for the best possible cooling at high ambient temperatures. The O-ring between the cooling head and the combustion chamber insert reduces vibration and protects against contamination in the best possible way. The 22E carburetor guarantees perfect response and maximum power development.
