If you want the best piston possible to install in your bike, look no further than the VHM Billet Series, offered in flat top or 12 degree.
The Flat Top series (or FT), are pistons that are manufactured from hammer forged aluminum, then machined out of a solid billet block of billet aluminum, and into their final dimension. They are the strongest piston made, detonation resilient, and proven to last longer than weaker cast pistons and forged series.
They are also elliptically machined on the exhaust port side, (hottest side of the piston), to account for heat and expansion, meaning it is intentionally made slightly oval, but when heated up to temp, holds a true roundness to the bore dimension resulting in superior performance and power.
The VHM flat top series can be used as a stock replacement and used with the stock heads.
