GRAND-SPORT MALOSSI 210 piston kit for MALOSSI 210/221 aluminium cylinder
Finally it is available! The brand new GRAND-SPORT piston kit for the MALOSSI 210 / 221 cylinder!
GRAND-SPORT piston kit especially developed for the aluminium MALOSSI 210/221ccm cylinder kit.
Available now as "0" size and as big bore with 69mm!!!
Piston kit with a modern layout and 18% sillicium alloy, offering an extended lifetime and a perfect shape stability.
2 extremly strong 1mm steel piston rings, providing maximum break resistance combined with maximum freedom for individual exhaust port shaping.
The position of the steel piston rings has been lowered by 1,5mm. This eleminates ring problems at the top edge of the cylinder when using a long stroke crank shaft.
The bottom area of the piston skirt is 1,5mm shorter, for preventing a piston contact to the engine case in case of useing a long stroke crank shaft.
Although the GRAND-SPORT piston is "stronger" than the original MALOSSI piston, the weight of this new piston is lower than the MALOSSI product.
The transfer port design offers an optimized gas transfer with more "out of the box" power in the whole RPM range.
CNC manufactured boostport windows are enlarged and reinforced.
Optimized piston pin clearance with lubrication grooves.
Biconic piston pin comes as a standart with the piston kit.
