Achieve perfect tuning for your SR500 with genuine quality!
Manufactured at Yamaha's designated factory with equivalent quality and quality control standards.
This is a high-precision, high-quality, MADE IN JAPAN 0.5mm oversize piston for the SR500.
Manufactured using the same low thermal expansion casting method as the genuine part, unlike short-lived aftermarket forged (machined) oversize pistons,
this oversize piston offers the same long-lasting durability as the genuine piston.
No need to fabricate and replace cylinder sleeves for repair by swapping to genuine STD size pistons.
Replaces discontinued genuine cast oversize pistons in all sizes,
allowing complete restoration of SR500s where proper repair with cast pistons was no longer possible, using only cylinder boring/honing.
