MVT cylinder kit and crankshaft for Derbi Euro 3/4

The MVT Thermal Group and Crankshaft Kit represents the ideal choice for those looking to enhance their Derbi, Aprilia, or Gilera (D50B) engine with a highly efficient system. This complete package includes an MVT Iron Pro Max cast iron cylinder of 90 cc, designed to deliver exceptional performance in sports applications. With its 7 transfers and a wide exhaust chamber with a booster, the cylinder ensures remarkable power at low revs, lightning-fast acceleration, and a significant increase in top speed.

The high-compression head, made from high-density aluminum and painted in an eye-catching orange, not only improves the aesthetics of the engine but also contributes to more efficient combustion. With a bore of 50.5 mm and a stroke of 44.8 mm, this kit is designed to withstand the stresses of intensive use, ensuring longevity and reliability.

The MVT SC crankshaft included in the package is built to tackle the challenges of high speeds and large displacements. Its high-load CNC connecting rod, with a length of 90 mm and a connecting rod pin of 18 mm, is reinforced to ensure superior strength. The filled masses optimize pre-compression, allowing for high revs with reduced vibrations, resulting in smoother and more efficient operation.

With a displacement of 90 cc and a piston pin of 13 mm, this kit is the perfect solution for those looking to take their engine to the next level without compromises. It is important to note that the product is not approved for use on public roads, making it ideal for sports applications and circuits.
