O.S.SPEED R2106 Racing Engine PBI

O.S.SPEED R2106 racing engine PBI (pre-run)

The O.S.SPEED R2106 PBI is a limited-edition, factory-tuned and pre-run (Pre-Braked-In) racing engine for 1/8 on-road competition. It uses the piston and sleeve from the Shimo Edition 3 – a 9-port sleeve with redesigned ports for better flow and more torque, and a new piston with three oil grooves.

For strong bottom-end power it has the crankshaft from the R21 Euro II and the popular ceramic ball bearing from the off-road engines. The new reinforced connecting rod, marked with an 'R', handles tough on-road races, and the carburettor is based on the 21M from the R2105 with a revised needle, slide and metering needle for easier tuning and better power from low to mid range. The head is black-anodised with laser-engraved logos.
