All IMD pistons are made from the latest specification silicon aluminum alloy material.
This conforms to the required percentages of specialist metals, the most important of which is silicon. Silicon has been proved conclusively over a prolonged period, to give the best ring groove wear rates coupled with a low coefficient of low expansion rates. Strength has been achieved using a modern construction technique which has allowed the weight to be reduced in the piston. The weight of the piston is the most important factor in engine design, since the effect of reciprocating weight is transferred directly in terms bearing loads, engine balance and maximum permissible speed. The lighter the pistons are, then the lower are the loads on the crankshaft main bearings.
IMD have achieved piston weights comparable with the original parts, and will in the future improve upon this through innovative design.
This reduction of weight is now common place in automotive piston manufacturing worldwide, our pistons conform to this industry practice without any compromise, and are kept to the lowest level concomitant with adequate strength.
Please note: All motorcycle & automotive components supplied from this site/listing must be fitted by a qualified Engineer using the correct appropriate equipment and using the necessary technical information. No liability can be accepted for components incorrectly fitted, and any such failure after installation.
