Wiseco PK1525 ProLite Piston Kit for Suzuki - 48.5mm 1991-2001 RM80

The Wiseco PK1525 is a ProLite forged piston kit designed for the 1991–2001 Suzuki RM80. With a bore size of 48.5mm (645M), this kit is engineered for top-end rebuilds and overbore applications on this popular two-stroke motocross platform.

Wiseco's ProLite pistons are CNC-machined from aerospace-grade forged aluminum, delivering a superior strength-to-weight ratio compared to cast pistons. The lighter reciprocating mass improves throttle response and engine efficiency, making this an ideal choice for competitive and recreational riders alike.

Kit Includes:

• Forged ProLite piston – 48.5mm bore diameter
• Piston ring set – pre-gapped and ready to install
• Wrist pin (piston pin) – precision-ground for accurate fit
• Circlips (retainer clips) – for secure wrist pin retention

Key Features:

• Forged 4032 or 2618 aluminum alloy construction for durability under high heat and load
• CNC-machined to tight tolerances for optimal ring seal and reduced blowby
• ProLite design reduces rotating mass for improved throttle response
• Hard anodized crown for enhanced wear resistance
• Direct OEM replacement fitment for the Suzuki RM80 (1991–2001)
• Manufactured in the USA by Wiseco, a trusted name in performance pistons since 1941

Whether you're rebuilding a worn top end or stepping up to an overbore for more displacement, the Wiseco PK1525 ProLite piston kit provides the quality and precision needed for reliable two-stroke performance.
