■ Final Notice Please ensure full understanding of the above before purchasing. This engine is a collaboration with ADAM DRAKE, a world-renowned driver supported by Ogawa Seiki, and is an improved version of the previous model. The crankcase features a boost bypass modification, resulting in smoother rotation and even easier handling. The new outer head features a two-tone anodized finish with blue anodizing, ADAM DRAKE's signature color, applied to the machined parts. This reduces weight and lowers the center of gravity, resulting in improved riding performance. It also incorporates a new laser design. By adopting a thrust plate for the cover plate, durability has been improved, and a further advantage in racing can be expected. Reducers of φ6.5II (for buggies) and φ7.5 (for truggy vehicles) are included as standard.
