NOS Wiseco piston set for T250 and GT250 - Suzuki T250J

T250's, GT250's and T350's have different size connecting rods which affects your piston choice. I choosed to use T350, GT 250 K/L connecting rods which have 21 mm small end eye diameter. Piston pin diameter in this case is 16 mm. T250's con rods normally have 18 mm small end eye diameter and the piston pin diameter is 14 mm. Other measurements in connecting rods are the same. T305' and T350's pistons have 16 mm piston pins. That is also one reason why I decided to go with GT250 K/L connecting rods.
