ESP Modified "High Rev / Lightweight" Zenoah 34mm Piston
ESP Modified "High Rev / Lightweight" Zenoah 34mm Piston
NEW ESP “High Rev” and “Light Weight” 34mm Zenoah piston.
This 34mm piston is great for racers around the world racing under EFRA racing rules, or anybody else who wants more performance from their 34mm bore Husqvarna/Zenoah engine, (works for CY 2-bolt cylinders also). It increases your exhaust duration by 5.5 degrees for more high rpm power, and is about 4 grams lighter than the stock piston, (less reciprocating mass), to help rev faster, with no loss in durability. If you are racing with your ported cylinder and wanting more high rpm power, or just want higher RPM power from a stock engine, you are missing out if this piston is not in your engine. As always with ESP, ESP performance and quality sets the standard for high performance Zenoah RC engines
