Description: 

Combo Set: TR03 EFRA2196 & MR04

Features:

This engine is a 1/8 on-road racing engine produced by O.S.SPEED.
The cylinder liner has a new 9-port configuration, and the port shape has been redesigned to improve power in the mid-range speed range. The crankshaft uses the proven EURO2 crankshaft, and in combination with a rear bearing with ceramic balls, the crankshaft provides improved feeling from low speeds. The connecting rods are newly designed and reinforced for improved durability during long hours of severe racing. The carburetor is based on the 21M carburetor that has been well established in the R2105, but the slide valve and needle shape have been changed to allow for easier adjustment.
The O.S. SPEED R2106 has been reborn as the O.S. SPEED R2106, which can be expected to offer an advantage in races.

• Newly designed cylinder and piston with 9 ports. The port shape has been changed to achieve torquey performance by reviewing the flow of the air mixture.
• The connecting rods are newly designed and reinforced to handle long hours of severe racing conditions.
• The letter “R” is engraved for identification.
• The outer head is black, the image color of O.S.SPEED, and has undergone exclusive laser processing.
• Ceramic balls are used for the rear bearing. This improves the feeling from low speed range.
• The use of the well-reputed EURO2 crankshaft improves mid- to low-speed torque and idling performance.
• Based on the 21M, which has also been well-reputed in the R2105, the slide valve and needle shape have been changed and revised for easier adjustment.
