This is a bore up kit that allows you to change the displacement to 178cc by changing the cylinder and piston. You can enjoy the torqueful output performance that is not found in normal engines. N-20 camshaft included Compatible models: Z125 PRO (BR125H-A02621~)

■ All-aluminum ceramic-plated cylinder The cylinder uses an all-aluminum ceramic-plated cylinder with excellent durability, airtightness, and heat dissipation. ■Compression ratio 178cc 11.5:1■Bore diameter 178cc 67mm■Stroke 50.6mm (normal)■ A stick temperature sensor can be installed on the cylinder. By purchasing SP Takegawa's compact LCD thermometer with stick temperature sensor, you can measure cylinder temperature. ■ Scut Piston The piston skirt of the aluminum cast piston is coated with molybdenum to improve initial fitting. ■ N-20 camshaft included Optimal profile that maximizes the performance of the stock cylinder head improves output performance. Built-in auto decompression mechanism similar to normal model. Precautions for use When installing the S stage bore up kit, it is necessary to install the FI controller TYPE-e (injection controller) at the same time. When using FI CON TYPE-e, you will need a computer or smartphone that meets the specified usage conditions. Also, you will need to be connected to the internet as you will need to download software and apps. Since the engine displacement is over 125cc, it cannot be driven on public roads with Class 2 moped registration. It will be for competition only.
