Hyper S-Stage Bore Up Kit (59mm/138.3cc/Plated Cylinder) KSR110

You can achieve 138cc by using the stock cylinder head and crankshaft and simply changing the cylinder and piston.
The Hyper S-Stage kit includes the S-Stage bore-up kit, a MIKUNI VM26 carburetor kit, and a spark plug.
The cylinder uses a ceramic-plated cylinder that offers excellent airtightness, durability, and heat dissipation.
Since Takegawa bore-up cylinders can accommodate a stick temperature sensor, you can measure the cylinder temperature by purchasing a separate thermometer.
If a 138cc bore-up kit is installed, registration as a Class 2 moped is not possible.
A muffler change will be necessary.
138cc Bore diameter 59mm Compression ratio 12.3:1
