The DOPPLER connecting rod is made of forged and ground solid mass with an aluminium balancing plug (which reduces dead volumes in the lower engine while guaranteeing maximum balancing and good inertia). It benefits from a heat-treated forged connecting rod and an INA silver nickel chrome plated needle cage for high engine speeds. The crankpin has been increased from 17mm to 18mm to handle higher loads - 12X17X15 needle bearing (ref: 451081)
