Product Details

The Wiseco 374M06700 is a high-performance forged piston designed for the Yamaha YZ and IT 175cc 2-stroke off-road engines (1976–1981). Machined to a bore diameter of 67.00mm, this piston is engineered to restore or improve upon factory performance in demanding off-road riding conditions.

Wiseco pistons are forged from a high-silicon aluminum alloy, delivering superior strength, heat resistance, and durability compared to cast alternatives. The innovative forging profile and precision-designed piston skirt geometry are optimized to maximize horsepower and torque output across the RPM range.

Kit Includes:

  • Forged high-silicon aluminum piston
  • Piston ring(s)
  • Wrist pin
  • Circlip(s)

Key Features:

  • 67.00mm bore diameter — oversize fitment requires professional cylinder boring or sleeving
  • Forged high-silicon aluminum alloy construction for maximum strength and longevity
  • Optimized skirt design for improved power delivery and reduced friction
  • Replaces OEM piston with a performance-grade upgrade
  • Complete kit includes rings, pin, and circlips for a straightforward rebuild

Please note: oversize pistons require cylinder boring or re-sleeving to match the specified bore diameter. Professional installation is recommended to ensure proper fitment and engine longevity.

Best price and decent shipping

fast and quick

Web site is very easy to follow or use. I'm thinking of finding other parts here. The battery has been delivered so quickly. It'd be better to see the order status changed from processing to shipping (or something) to know that it actually was shipped. But that's a small thing. I'll try other replacement parts here next time.

I will like to get that bracket ASAP

Fast and friendly

What I wanted at the best price available with free shipping, how can you go wrong.

Shopping here was a breeze.. Information was clear and helpful. I will definitely consider shopping here in the future.

Quick

Ordered on Sunday, called on Monday for tracking #, received product on Tuesday, and received tracking # on Wed!! I got the item before Autoplicity got a chance to send me the email with the tracking #. A+++!!!

Best price I could find! Great customer service kept me informed through the whole order process to insure acuracy since it was being sent directly from the manufacture. Recieved my order in good time, right parts and no damage. Overall very satisfied and will be doing business again in the future.
