This high-performance piston set is designed for the Yamaha FZ150, YZF155K YZF R15 SP 2014, YZF155K YZF R15 2011-2014, and YZF155K YZF R15 2015-2018 models (excluding the R15 VVA Version 155cc 2018-2019). Crafted from durable aluminum, the piston features a standard bore type with a size of 58.00mm. The wristpin diameter measures 14mm, and the wristpin height is 39mm, while the piston height is approximately 32mm.

The package includes a piston, a piston ring set, a wristpin, and two circlips. These high-quality components have been manufactured using the latest computerized technologies derived from the world of GP and F1 racing. The forged pistons are more temperature resistant and longer-lasting than their cast counterparts, and they also feature a piston skirt coating for enhanced performance and durability.

The piston set is designed to provide an airtight function, preventing gas leakage from the top of the piston. The piston ring also helps to dissipate heat effectively, ensuring optimal engine performance. Furthermore, the ring is engineered to prevent excessive oil from entering the combustion chamber while fully lubricating the cylinder wall, maintaining the proper direction of piston movement.

It is important to note that professional installation is highly recommended, as no installation instructions are included with the kit. Please check whether your model and parameters are consistent with the specifications provided, as there may be a 0.5-1mm variation due to manual measurement.

The piston dome is anodized for superior heat resistance and a longer lifespan, ensuring that your engine can withstand the demands of high-performance riding. This comprehensive piston set is an ideal choice for those seeking to upgrade or replace the original equipment in their Yamaha FZ150, YZF155K YZF R15 SP 2014, YZF155K YZF R15 2011-2014, or YZF155K YZF R15 2015-2018 models.
