The stock cylinder head and stock crankshaft can be used without modification. Fits all years/models of the KLX110 and DRZ110. Only works with stock head and valves.
Displacement = 138cc
Bore Diameter = 59mm
Compression Ratio = 12.3:1 (pump gas ok)
The cylinder is a ceramic plated cylinder which has excellent airtightness, durability, and heat dissipation.
SP Takegawa's big bore cylinders can be equipped with a stick temperature sensor, so you can measure the cylinder temperature by purchasing a thermometer separately.
The combustion chamber shape and compression ratio have been balanced to achieve high combustion efficiency and reduced weight. The piston skirt is coated with molybdenum for better initial adhesion.
