These are basically a "decked" 250cc cylinder that has had height removed to match the stroke length of the 125 conrod by S3. All the machining is done at the S3 Factory Spain.

S3 are the original equipment suppliers of cylinders to GASGAS, so this is exactly the same quality as the original cylinders.

So a 250cc top end, bolted to a 125cc bottom end in essence - giving a capacity of 225cc.
