KEEP.21M Direct Drive
The conrod is made from superlight & superstrong alluminium to make the lightest and strongest possible conrod to withstand the abuse of a racing engine.
The sleeve has 9 transfer ports and an exhaust with booster ports. The special shape and positioning of the ports, covered by a patent, improve the internal fluid-dynamics to obtain the maximum possible performance.
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.
