The cooling head has been re-designed so that it is mounted lower on the case for a lower center of gravity, with additional machine work to reduce weight and improve cooling efficiency, the addition of a ceramic rear bearing helps to improve acceleration and fuel efficiency, while minimizing wear and vibration. Piston: This piston was milled from a single block of specialized aluminum, chosen for its excellent strength to weight properties. The shape of the top of the piston is features'Compact Combustion Technology' which improves the efficiency of the engine.
Conrod: The R7 conrod is made from super light aluminum which has been ultrasonically checked. The specific form of the R7 rod creates minimal turbulence inside the engine while running. Sleeve: The sleeve has 9 transfer ports and an exhaust with booster ports.The piston features a new special black superficial treatment that reduces friction and improves piston strength. Rear Cover: The rear cover features a round shape to optimize crank case volume and reduce the dead space. The steel plate is used to reduce friction and to expand the lifespan of the conrod. Front Bearing: The Front Ball Bearing has a thickness of 5mm, to prevent fuel spillage between the carter/crankshaft and the bearing. Combustion Chamber: The combustion chamber is supported by an O-Ring which is placed between the combustion chamber and the crankcase to reduce combustion chamber vibrations.
Crankshaft: The crankshaft is grinded to increase the mixture flow and has a special shape to reduce turbulences inside the crankcase. The balancing is done by 3 inserts made of tungsten alloy and the inlet has a silicon filling to reduce the weight of the crankshaft to improve acceleration. Glowplug: The glowplug is a Turbo type glowplug. Turbo glowplugs have a different shape than Standard glowplugs and are not interchangeable with Standard glowplugs!Specifications: Displacement: 3.49cc Max. Practical RPM Range: 6,000 46,300 R.
