INNOVATION FROM DR FOR FANS OF THE VESPA ET3!12-12-2018
Following demand from the market for high performance kits for the Vespa ET3 Classic small frame, DR, a well-known brand in this field, has recently completed development of a conversion which will fully meet the requirements of the most demanding owners of these legendary Piaggio scooters. The kit is based on an aluminium cylinder with nickel-silicon galvanic coating, with a 57 mm bore, 130 cc displacement, characterized by distribution through 6 transfer ports and elliptical exhaust. The piston is cast in aluminium alloy with a high silicon content and 2 segments to ensure maximum tightness even in extreme conditions of use. The high turbulence head has a calculated squish band with the spark plug in the traditional position. The main advantage of this thermal assembly is the balance which the technicians have managed to achieve in terms of power delivered and the corresponding quality. This puts the assembly at the mid-way point between basic cast iron thermal assemblies and extreme assemblies used at competition level, a compromise ensuring great satisfaction for those driving these wonderful classic scooters.
