Cylinder kit & Tuning ECU Malossi 180cc Yamaha MT-125 from year 21, XSR 125 from year 22 onwards

A bundle for all those who want to know!

Consisting of: Malossi I-Tech 180cc cylinder kit (3117968) + ECU engine control unit Malossi Force Master (5519283B)

The Malossi I-Tech 180cc cylinder kit consists mainly of an aluminum-silicone alloy. It is coated with a silicone carbide layer, which has been cross-ground to ensure optimum lubrication. Due to the new material composition, the thermal conductivity of the cylinder has been further improved.

The very compact and therefore very light piston, designed with three piston rings and a tin surround on the sliding surfaces, is also made from a special aluminum-silicone alloy. It has a very low thermal expansion.

The piston rings are very stable and have excellent sliding properties:

• Ring 1: Ring for compression
• Ring 2: made from special pig iron
• Ring 3: Oil scraper ring

Technical data:

• Bore: Ø 63 mm
• Stroke: 58.7 mm
• Displacement: 183 cm³
• Compression ratio: 11.27

ECU engine control unit Malossi Force Master

In addition to the improved fuel curves, the efforts of Malossi's technical staff led to an increase in the rev limiter depending on the vehicle, making Force Master 2 an even more powerful ECU! Force Master 2 makes it possible to change the injection to perfectly match the Malossi 4-stroke and original cylinders.
