S-Stage+D Bore Up Kit (Scat/106cc) 12V Monkey, CRF50

The S-Stage allows for an increase in displacement while retaining the stock cylinder head and crankshaft.
Furthermore, the S-Stage 88cc offers a choice between the "Standard" type, which requires high-octane gasoline, and the "eco" type, which uses regular gasoline.
The conventional Standard type had a compression ratio of 11.5:1, recommending high-octane gasoline, but the S-Stage eco has a compression ratio of 10.5:1, making it possible to use regular gasoline.
This can reduce fuel costs.
Displacement: 106cc
Type: Standard
Cylinder: φ57 Scat Cylinder (All-aluminum ceramic-plated cylinder with excellent durability, airtightness, and heat dissipation)
Included Camshaft: With decompression
