O.S. Engine 28XZ Truggy Engine  [OSMG2074]

With input from top truggy drivers, O.S. has developed the best motor for these hybrid hot rods! The 28XZ produces more low-end torque, providing the rpm/torque balance that weightier truggies require. The effect is energy that??s extremely smooth, for truggies more drivable than ever before thought possible!

The larger head supports cooling, and is a 2-piece construction with inner mind key.
A sealed front bearing and high-performance internal bearing are area of the new crankcase design.
The high-performance con pole features oiled bushings.
Three needles enhance fine-tuning regarding 21J slide-valve carb.
Is sold with a high-performance P3 hot turbo plug.
The Mark Pavidas Edition Tuned Pipe (OSMG2969) could be the perfect accessory for the 28TZ; flywheel sets are needed (OSMG2648 for Mugen, OSMG2649 for Kyosho, both sold individually) for many truggy models.
