Customer Reviews

Is as it should be. Great piston

Great as usual with Wiseco.

Excellent

Everything great

Exactly what they say in description great quality hope for many hrs out of these pistons.

These pistons are exactly what I needed. The quality is very high and I believe they will serve this engine for years to come!

Awesome parts.

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.

I bought this kit and I must say I don't regret it one bit, this piston is the way to go

It fit good and added a good bit of power

Very pleased with purchase.

I have an early 80's street and dirt bike that are hard to find parts for. The parts are top quality.

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

The piston was exactly what I ordered and it is working well.

Absolutely amazing they're in my hand 16 hours after. Beautiful pistons. Thank you so much and I enjoyed the stickers.

Amazing, thank you.

Easy rebuild parts were to spec. Bike runs great.

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.

As promised. I will look to parts giant in future.

Great
