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 world famous OS Max precision and technology together with some additional '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 "EXPERIENCED" users.

Features:

Super Long Stroke
7 Ports with MES
CNC machined piston
14mm DLC(Diamond Like Coating) turbo crankshaft MODIFIED 'Rody', balanced, internal ground-rounded, lightened and silicone paste
Competition Con-rod
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 carburetor with single adjustment
8.5mm aluminum restrictor

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 con-rod. The crankshaft itself will resist better against wear on the con-rod area but also at the intake area where sometimes dust passes.
