The new and exclusive VS Racing 2102R super long stroke .21 on-road engine is based on the very powerful O.S. Speed R2101 and is an extraction of the worldfamous OS Max precision and technology together with some addional 'Rody' touch and development, equipped with a VS Spec combustion chamber. 

The VS Racing 2102R is suited for high competition 1/8scale on-road racing.
This engine is intended for "EXPIERIENCED" users. 


  • Super Long Stroke
  • 7 Ports with MES
  • CNC machined piston
  • 14mm DLC(Diamond Like Coating)turbo crankshaft MODIFIED 'Rody', balanced, internal grinded-rounded, lightened and silicone paste
  • Competition Conrod
  • Turbo combustion chamber VS Spec.
  • 14mm high-speed main bearing
  • 7mm high-speed front bearing with rubber protection
  • VS Spec. Super lightweight cooling head
  • VS crankcase
  • VS spec. aluminum lightweight slide carburettor with single adjustment

A special interest goes to the DLC coating technology wich will increase the lifespan of the rotating parts, especially in the piston-area where the pin is exposed to high pressure from both piston and conrod. The crankshaft itself will resist better against wear on the conrod area but also at the intake area where someteimes dust passes.
