Short Description: Restore your engine's compression and peak efficiency with this comprehensive piston overhaul kit. Engineered for maximum durability and precise fit, it is the ideal solution for returning your Dnepr MT-11 to its original heavy-duty performance.

Technical Specifications:

• Compatibility: Dnepr MT-11 (Model KM3-8.155.6 and compatible series)
• Manufacturer Code / SKU: MT8012-3
• Part Type: Engine / Crank Gear

Purpose and Role in the Motorcycle (based on the original manual):
The pistons are the central components of the engine's crank gear, acting as the primary moving boundary within the combustion chambers. In the Dnepr MT-11, these pistons are designed for a 78 mm bore and feature a critical 1.5 mm offset of the pin hole axis from the longitudinal central plane, which ensures smooth movement and minimizes impacts during the transition at the upper dead center. This kit includes a specialized four-ring configuration: two upper compression rings to ensure airtightness and prevent gas leakage into the crankcase, and two lower oil scraper rings (including a four-element steel assembly and a cast iron ring) to remove excess oil from the cylinder walls. According to the technical manual, the primary sign that these components require replacement is when engine oil consumption exceeds 0.25 liters per 100 km, or when a loss of compression is noted.

Benefits of Buying:

• Exact Technical Fit: Manufactured to strict factory specifications, including the essential 1.5 mm pin offset for reduced engine vibration and wear.
• Optimized Oil Control: High-quality scraper rings significantly reduce oil consumption and prevent carbon buildup on the piston crown.
• Complete Restoration Kit: Includes the pistons, rings, floating pins, and spring lock clips for both cylinders, providing everything needed for a professional top-end overhaul.
