FOR VESPA GTS / GTS SUPER 

TECHNICAL SPECIFICATIONS

Cylinder

  • Bore Ø 75.5 mm;
  • Stroke 63 mm;
  • Displacement 282;
  • Compression ratio 12.5:1.
  • Material: primary aluminium alloy with a high content of hardened and tempered silicon, cylinder liner with silicon carbide coating in a galvanic nickel die and crossed smoothing with two diamond passages with very limited tolerances.
  • Machining: on machine tools with high precision numerical control.
  • Cylinder-piston connection with an allowance of 0.05 mm.
  • Recalculated and upgraded heat exchange surfaces.

Piston

  • Ultra compact with 3 rings.
  • Material: special aluminium alloy with high silicon content, low thermal expansion and a tin facing on the sliding surfaces.
  • Machining on machine tools with numerical control.
  • Lightened and reinforced.
  • Upgraded heat exchange surfaces.

Piston rings

  • Special rings with high sliding ease and very high mechanical resistance.
  • I° ring compression in nitrided and chromium steel.
  • II° special cast iron ring.
  • Three - piece scraper ring made of chromiumplated special steel alloy.

Head

  • Head made of gravity-fed cast aluminium alloy, tempered and sandblasted, machined within thousandth (mm) tolerances utilizing super precise work cells.
  • Valve guides designed with new profile, made using a powdered metal sintering process (steel, phosphorous, carbon, copper and manganese).
  • Valve seats made of cobalt-molybdenum steel alloy characterised by copper infiltration and a special heat/chemical treatment. Increased intake valve - ø 25 mm, made of a special steel alloy and a special heat/chemical treatment.
  • Increased exhaust valve - ø 22.2 mm and made of Nimonich 80 material (Nickel, Chromium, Titanium, and Aluminium alloy).
  • Exhaust and Intake valve springs made of Si-Cr oil-tempered and annealed steel, designed to operate optimally under increased loads due to increased engine power.
