Where I mostly ride I think I am pretty set with 300cc. I am running 14/47 gearing and it gets a little buzzy at 65mph on the street but I only use the bike on road for short commutes and to get to trails. Offroad in the woods it has more than enough power and I can easily loft the wheel for obstacles.

I think that the only way I would go to 331 would be if I got a different bike for offroad and the klx got a sm conversion.
