I know my fellow latin americans and trust me, there are a lot of bull going around those 300cc conversion... They are not 300cc, but actually a 250cc conversion.
The base engine is a CG 200 which has a stroke of 62.2 mm now if we add a 72 mm piston we have an engine with a displacement around 253cc... A Far cry from a 300c.
If we use a cg250 which has a stroke of 65 we have an engine that has around 265cc displacement
Yes the cylinder says 300cc but because it was meant to be matched with an engine with a different stroke.
In this area of the world the history goes like this.
Dude without a lot money waste money on a 300cc conversion, tries to race an Honda CBX 250 or even worst a Ktm duke 290, not only they lose because they are outclassed by better engines but they trash their own engine.
