PISTON SUZUKI RM 250 1987-1988 WISECO 558M06700 67.00 1 FASCIA

The WISECO pistons, manufactured in U.S.A., are produced by forging, have no grads increases and their size indicated is the rated (that is, referred to the nominal size of the cylinder). This particular feature is typical of every Wiseco piston, developed and used in its 70 years of production. The Wiseco forged pistons have in fact a different, but calculated, expansion than any other competing product that allows you to use profitably only one measure in a new cylinder or moderately worn. This is possible thanks to the uniqueness of the characteristics of the aluminum alloy used, the advanced study of expansion, then the thickness at any given point of the piston and to the particular forging system. In fact, using a piston A - B - C of a cylinder too worn or oval is only a palliative, also often used pairs A - B - C too precise that increasing the friction reducing, in fact, the engine performance. The Wiseco pistons have proven over time as the best compromise between durability and performance. Below are the items for immediate availability. For the models and items not listed please visit the site www.WISECO.com and / or contact our sales department for more information. Installation should only be carried out by professional staff, following the instructions in the motorcycle manufacturer and in any case after verification of the adaptability and the correct compression ratio BEFORE installation. They are supplied complete with bands, latches and the plug is included in almost all models. The SERIES GP words identifies a piston high performance, with a firm central band to allow machining to the transfer ports on the cylinder without the hole on the mantle suction side; the area of ​​the piston ring of the piston and the piston pin undergo a special anti-wear treatment. The words SKIRT COATED identifies a piston to which it has been reported, on the mantle, a special treatment permanent friction that, unlike competing products, not only serves to facilitate the break-in period, but permanently lowers the friction coefficient. The words CHOICE RACING identifies the most powerful model produced by WISECO. Main features: • "DLC treatment" on the plug • Internal structure to "bridge" • anti-friction treatment "skirt coating" • Privacy wear on the piston and piston rings hollow • High compression ratio • Treatment "TITANIUM NITRIDE" piston rings for better sealing
