S-Stage Bore Up Kit (φ57mm/106cc/SCUT) for 12V Monkey/XR50R/CRF50F

S-Stage allows you to increase the engine displacement while keeping the normal cylinder head and crankshaft.
Furthermore, the S-Stage 88cc offers two options: "Standard" for high-octane gasoline and "eco" for regular gasoline.
The conventional Standard model had a compression ratio of 11.5:1 and recommended 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: Without decompression
