High quality crankshaft bearings VOCA C4. Includes VITON oil seals. For gearbikes equipped with Derbi E2 or Derbi E3 engine.
A true “High-Tech” electric pump that is manufactured with a polymer casing that guarantees a reduced weight and resistance to high, low temperatures, humidity, acids and hydrocarbons. The motor of the pump is brushless what avoids wear, noise and heat. But above all it reduces the consumption and offers us a long life of the pump. The original mecanical water pumps of the majority of bikes are driven by the crankshaft and rotate at the engine revolutions, so they do not always offer a necessary flow of cooling liquid. For example at low RPM.
New reenforced high quality VOCA crankshafts for tuned gearbikes. Elaborated of high quality materials only, completed with black anodized aluminium inserts which lower the weight of the crankshaft and increase the performance of the engine. VOCA crankshafts are made to resist and to enhance the performance of most powerful cylinders. Equiped with CNC machined conecting rod and silver needle bearing. Standard measures, validated up to 16.000 RPM. Available for Derbi Euro2, Derbi Euro 3 and Minarelli AM6 engines.
Automatic VOCA Racing waterpump cooling kit for Derbi E3 / D50B0 engines. The original Derbi waterpump has a very limited water-flow and cooling performance. Especially in highly prepared engines a much better cooling system is needed. The VOCA cooling kit substitutes the mecanic for a much more efficient brushless electric waterpump (waterflow 25 L/Min) which on top is conected to a new flow optimized waterpump cover. The waterpump is automatically activated by a thermocontact, no aditional switch is needed. The instalation is simple, any user with basic know-how can handle it. VOCA Derbi E3 cooling kit: – CNC machined red anodised waterpump cover. – Brushless waterpump: 25L/min, 12V, Ø conection 15mm. – VOCA CNC machined T-Link 1/8″. – Equiped with thermocontact: range 70ºC (ON) – 60°C (OFF).
