Wossner Airsal 200cc Piston for Yamaha Blaster
The Wossner Airsal 200cc piston is a premium forged replacement piston designed specifically for the 66mm Airsal cylinder used on the Yamaha Blaster YFS200. This KOR-exclusive piston gives Airsal cylinder owners a high-quality forged option for rebuilding or refreshing their top end.
The standard replacement piston supplied for many Airsal kits is cast aluminum. This exclusive Wossner piston is forged for increased strength and durability in demanding two-stroke applications. It is an excellent choice for trail riding, recreational use and performance Yamaha Blaster engine builds.
Designed Specifically for the Airsal Cylinder
This is not simply a standard Yamaha Blaster piston placed into an Airsal cylinder. The piston is manufactured for the dimensions and requirements of the Airsal 200cc Yamaha Blaster cylinder kit.
Correct piston selection is especially important in a two-stroke engine. Piston dimensions, ring placement and cylinder clearance must all be compatible with the cylinder and ports. Using an incorrect piston can cause poor performance or serious engine damage.
Premium Forged Wossner Construction
Wossner is known worldwide for manufacturing high-quality forged pistons for motorcycles, ATVs and other performance engines. Forged aluminum construction provides excellent strength for engines that operate under elevated temperature, RPM and cylinder pressure.
Benefits include:
- Strong forged-aluminum construction
- Excellent dimensional stability
- Suitable for performance applications
- Dependable replacement for a worn Airsal piston
- Manufactured by an established performance-piston company
Yamaha Blaster Fitment
This piston is intended for Yamaha Blaster YFS200 engines equipped with the Airsal 200cc 66mm cylinder. It is not intended as a direct replacement piston for every stock OEM Yamaha cylinder.
Verify that your engine has the correct Airsal cylinder before ordering. Cylinder condition, bore diameter and piston-to-cylinder clearance should always be checked by a qualified engine machinist before assembly.
Professional Cylinder Inspection Recommended
Never install a new piston based only on the size marked on the old piston. The cylinder should be cleaned and accurately measured to determine its condition and required clearance.
If the cylinder is worn, damaged or out of round, additional cylinder work may be necessary before installing the new piston. Correct measurement, ring-gap inspection and assembly procedures are essential to achieving proper performance and service life.
