4. Improved ring sealing: The piston features a low-tension piston ring set that provides better sealing and reduces the chance of blowby.

1. Cost: The Wiseco piston is more expensive than the stock piston.

2. Installation: Installing the piston requires the removal of the engine from the motorcycle, which can be a time-consuming and labor-intensive process.
