Short Description: Restore your engine's compression and peak performance with these precision-engineered standard pistons. Essential for any professional engine overhaul, these pistons ensure maximum reliability and smooth operation for the Dnepr MT-11.

Technical Specifications:

• Compatibility: Dnepr MT-11 (Model KM3-8.155.6 and compatible variants)
• Manufacturer Code / SKU: KM3-8.15501237
• Part Type: Engine (Crank Gear)
• Diameter: 77.95 mm (Standard)

Purpose and Role in the Motorcycle (based on the original manual):
The piston is a fundamental component of the Dnepr MT-11's crank gear, acting as the primary interface between the combustion of the air-fuel mixture and the mechanical movement of the crankshaft. These pistons are designed with a four-groove configuration to accommodate two compression rings for airtightness and two oil scraper rings to manage lubricant on the cylinder walls. A key engineering feature is the 1.5 mm offset of the piston pin hole from the longitudinal central plane, which minimizes piston slap and ensures the piston moves smoothly within the cylinder without excessive impact at the upper dead center. Owners should look for signs of wear such as excessive oil consumption (exceeding 0.25 liters per 100 km) or a significant drop in engine power as indicators that the piston and ring assembly requires replacement.

Benefits of Buying:

• Exact Factory Specifications: Manufactured to the precise 77.95 mm standard, ensuring a perfect fit within the 78 mm cylinder bore for optimal compression.
• Enhanced Engine Longevity: The precise pin offset reduces internal mechanical stress and noise, contributing to a smoother ride and a longer engine lifespan.
• Restored Oil Control: Replacing worn pistons eliminates excessive oil consumption and reduces carbon buildup in the combustion chamber, improving overall fuel efficiency.
