S Stage eco Bore Up Kit
Sports Camshaft

You can enjoy Torque fully output performance which is not in NORMAL.

■ S Stage Bore Up Kit181cc
It is Bore Up Kit which can change Engine Displacement Volume from NORMAL124cc to 181cc by changing Cylinder and Piston.
FI Controller TYPE-e (Injection controller) Simultaneously wearing it realizes Torque fully output characteristic different from NORMAL.
Cylinder adopts All Aluminum Ceramic plating cylinder excellent in durability, airtightness and heat dissipation.

Piston is an eco corresponding to RegularGasoline

■ Sports Camshaft (N-20)
The optimum profile that derives the performance of Normal cylinder head to the maximum Large limit improves output performance.
By installing it in the Normal engine, the output in the high speed range will be improved.
Sports Camshaft (N-20) Normally, if you remove DecompressionParts from Standard Camshaft and attach it to Sports Camshaft, it becomes Automatic DecompressionSpec.

*It requires a simultaneous installation of FI CON TYPE-e (injection controller) when S stage bore up kit is installed.
*It cannot travel on public roads by registering two types of mopeds because the engine displacement is 125cc or more. It is exclusive to competition.

*About installation of S stage bore-up kit
It increases the burden of twist and deflection on the crankshaft with the installation of the high comp Piston kit by SP TAKEGAWA because the engine output and torque are greatly increased.
It is recommended to install crankshaft support adapter at the same time in order to reduce the burden on the crankshaft at SP TAKEGAWA.
The crankshaft support adapter adds support by ball bearings to the end of the crankshaft flywheel side, thereby suppressing twisting, deflection, etc., and enhancing the durability of the crankshaft.
It is a crankshaft support adapter for MONKEY 125 (JB02) 01-10-0138
