Piston: The material of this piston is choosen for its excellent strength to weight properties. The shape of the top of the piston is our 'Compact Combustion Tecnology' which improves the efficiency of the engine. This piston is also milled from a single block which further increases the strength.
Sleeve: This Piston/Sleeve set is optimized for use in EFRA/IFMAR competition events and is made from hard chromed brass and features 9 transfer ports.
Crankshaft: This is a special crankshaft. Made to meet even the highest standards of our most demanding drivers. Slightly reduced rotational mass and greatly improved fuel flow provide great performance.
Compression rings: The ignition timing is controlled with these little rings of various thickness. To change the ignition timing you can add or remove a ring of a certain thickness.
Conrod: The conrod is made from superlight&superstrong alluminium to make the lightest and strongest possible conrod to withstand the abuse of a .21 racing engine.
