They had the part and I got it in 3 days. I was in a hurry before a long weekend ride. Installed piston and it fired on first kick. Wiseco has good premium parts, you do have to pay for they, but you get what you pay for.

Part was as described. But I'm giving 4.5 stars out of 5, only because I didn't get any stickers! Ha

Amazing product
By Mike P on
Verified Purchaser
The packaging of the product was great. The Wiseco piston came in a velvet bag, the piston rings were in a seal plastic bag then package in a cardboard box, the wrist pin was package in the corner of the product box with it's own compartment.
Installing the product was quick and easy. The directions were spot on. I purchased a 13:1 compression kit. After installation, the engine ran stronger and the throttle was snappier. Overall, I'm extremely pleased with this product, I would recommend this product to anyone wanting to a little more out of their stock engine, and I'm so pleased with this product that I'm buying another one for my other Yamaha Raptor 250.
Pistons for a classic.

Questions & Answers
If I order this for a 2020 kx250, will it have the stock compression ratio? It needs to be 14:2:1
By Ben K.
If you were to select the 2020 Kawasaki KX250 4-Stroke piston from our fit guide, and assuming all the remaining cylinder and gasket components remain stock, the piston you'd receive will provide a 14.2:1 compression ratio.
This pistons and gaskets?
By Anon.
If you want a piston and gasket in one box, check out the Wiseco Piston Kit. Those will come with the piston and a top end gasket kit, all in one package.
