。

Based on the overwhelming performance of R2101 with consecutive winning of Shinnosuke Yokoyama of OS works in Japan NATS, OS Speed again reengineered each element　to seek better performance than R2101 for new R2102.  The outer head is 3mm lower than the previous model to gain lower central gravity without sacrificing heat dissipation.  A newly adopted ceramic rear ball bearing reduces frictions.  An extra inner head, an standard accessory, increases torque in low-middle range.  It is also suitable for 16% nitro fuel.
