Description
If you’re running a KX250F or RM-Z250 and want measurable gains in peak power and mid-range response, a high-compression piston kit is one of the most direct bolt-on upgrades available. The Wiseco 4843M07700 delivers a 14.1:1 compression ratio with aerospace-grade forged aluminum construction—purpose-built to handle the sustained heat and detonation stress of competitive 4-stroke racing.
