OS SPEED R2106 COMBO (TB03 EFRA2196 + MR05) COMPLETE SET

This is O.S. Engine R2106 Onroad Engine w/TR03 EFRA2196 & MR05 Pipe Combo Set. The OSSPEED R2106 is a new factory-tuned engine designed for 1/8th-scale on-road racing competition. The new 9-port cylinder liner with redesigned ports provides more power. For a great low-end power feel, we adopted the crankshaft from the R21 Euro II, as well as the well-proven ceramic ball bearing from the off-road engines. The redesigned reinforced connecting rod is now stronger to withstand all the tough on-road racing conditions.

Feature:

The 9-port cylinder liner with redesigned channels improves flow for more torque and a new piston with 3 oil grooves.

The redesigned reinforced connecting rod is now stronger to withstand all the harsh on-road racing conditions.

*The letter "R" is engraved on the connecting rod for identification.

The outer head is black anodized with laser engraved OSSPEED and R2106 logos.

The rear bearing is a ceramic ball bearing for a better feel at low revs.

The crankshaft comes from the R21 Euro II engine for more power and a better mid-speed feel.

Based on the 21M carburetor of the R2105, the R2106 carburetor features a revised needle, slide valve control and metering unit for easier adjustment and better low to mid-range power delivery.
