JE Pistons Yamaha YXZ1000 12.5 to 1 Piston Single

Forged from high-strength aluminum alloy, this JE Pistons single piston is built for the Yamaha YXZ1000. It features a 12.5 to 1 compression ratio, which is a notable increase over stock, designed to help you get more power out of your engine. JE Pistons is a well-known name in performance engine building, and this piston reflects their focus on creating durable components for demanding applications.

This piston is a single unit, meaning you'll need to purchase the correct quantity for your engine. The 12.5:1 compression ratio is achieved through a specific dome design, carefully machined into the piston. This level of compression requires proper tuning and potentially higher octane fuel to prevent detonation, but it can significantly change how your engine performs when set up correctly. JE Pistons are well-made and designed to handle the increased stresses that come with higher compression and performance tuning.
