Engine VS Racing VS-R05 by Rody Roem
The new and exclusive VS Racing VSR05 super long stroke .21 on-road engine is based on the very powerful O.S. Speed R2102 and is an extraction of the worldfamous OS Max precision and technology together with some addional 'Rody' touch and development, equipped with a VS Bi-Turbo crankshaft and VS Spec combustion chamber.
The VSR05 is suited for high competition 1/8scale on-road racing.
A new piston/liner 9 ports for more faster climbing in rpm and in addition a new cooling-head where it is more easy to reach the engine fixation screws.
Features:
- Super Long Stroke.
- 9 Ports with MES
- CNC machined Euro-Spec. piston.
- VS Spec. 14mm MODIFIED 'Rody' DLC(Diamond Like Coating)Bi-Turbo crankshaft, lightened and silicone paste.
- Competition Conrod.
- VS Spec. Turbo combustion chamber.
- 14mm high-speed main bearing.
- 7mm high-speed front bearing with rubber protection.
- VS Spec. R05 Super lightweight cooling head
- VS Spec. crankcase.
- VS spec. aluminum lightweight slide carburetor with 8.5mm aluminum venturi.
A special interest goes to the DLC coating technology which 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 sometimes dust passes.
