Starting with the .21 buggy engines, the Legend 7 and Legend 4 Off Road engines both offer a long stroke design, new rear ball bearings with less rotational mass, redesigned 3-needle carburettors and updated venturi inserts for optimised performance. Both engines are available with standard steel or ceramic bearings.

Venturi:
This Alloy venturi is specially shaped to minimize the boundry layer build up. With this special shape it will maximize the potential performance out put of your engine.
  Rear ball bearings:
The new ball bearing reduces the inertia of the rotating masses and increases the engine's scavenging. You can see both the ball bearing and the manufacturing process result in the picture above. These novelties give an increased throttle response and a higer top speed.
  Coolinghead:
NEW COOLING HEAD.
  Carburettor:
The new three tuning needles gives a better idle and improves the ability of the engine to return to low rpm after throttling.
