Crankshaft -STOFFI Racing (rotary valve) 60mm stroke- Vespa PX200

partnumber 7676163

Sports crankshaft from Austrian legend „Stoffi” made by Tameni. Good choice for all daily runners with Standard, Pinasco 213/225, Polini 207/210/221 or Malossi 210 Sport Cylinder.
With the inlet closing near at 65° ATDC (depending on casing) the engine is easy to jet in, without all the trouble you get from a crankshaft with blow back created due to a too long inlet timing.

Sadly not as wide as a bgm crankshaft, measuring at the inlet crank web. Therefore you have to be careful not to open the inlet area to wide.

  • Inlet timing closing: 65° ATDC
  • Stroke: 60mm (standard 57mm)
  • Con rod lenght: 110mm (as standard)
  • Suitable Engines: PE200, PX200, Cosa200, Rally200 (Ducati Iginition)
  • Crank pin: 20mm (full material)
  • Necessary stroke compensation: 1,5mm Spacer (Base or Head, only cylinders made for 57mm stroke)
