B

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.
