Bored to a I don't think that's even possible unless it's bored and stroked

Never heard of a 600cc KFX450 🤦🏻‍♂️ people must make up this shit. I literally do atv and Mx performance. The biggest is the 512 stroker. But you could put a camshaft to improve its power as well but that does not make it a 600 lol.
I’m currently building a KFX450 with a 500 stroker. Had the 490 Athena but it will dragsticallt improve the mid range torque with the stroked crank and the high compression piston. With a 98mm instead of the 100mm it will make better top end power because it isn’t stroking a larger piston. With the right engine components and tuning the 500 is really good.
The 512 in my opinion is too much bottom end and slow honestly.

Shake your head that is not a fucking 600 if it's a 600 youd have a billet cylinder
