SPI replacement pistons?

[CdnSxR6]

Looking at top end maintenance on a Viper. Complete kit using SPI pistons on Ebay (item 271128915990 ) for $250.

Any opinions or experience with them?

I would always stick with OEM pistons as they are the best for your Yamaha.Some things you can go for aftermarket are things like bearings,idler wheels,belts..but when it comes to the motor..best is to stick what Yamaha uses as they designed the motor.

I have been useing them in my 98 for 3 seasons now.Cant realy say anything bad or good about them other than the price.They seem fine.
