Introducing the all new kit 50cc DOPPLER called Vortex for DERBI Euro 3, which is the evolution of ER1. First start on design, as you can see it is like no other high engine. The mold is totally different which is not unpleasant to see, on the contrary it will allow you to distinguish yourself from others. Cooling is obviously improved with a new architecture!

This kit is very high quality aluminum, a nykasil premium treatment to give you maximum strength. Then the exhaust is a strip pattern like most competing models, admission transfers are 5 in number and they are redesigned for better performance / better filling. Preferred is a simple but éfficace system a complex system has 6, 7 or 8, often fragile and rather trade transfers!

  The cylinder head is a polished hemispheric model the studied form that will ensure optimum combustion. This cylinder head allows you to reconnect if desired antifreeze on your carburetor. This cylinder head provides excellent compression ratio.

The piston is a model VERTEX, very high quality silicon content along two chrome segments 1mm thick to push hard in high revs (reductions in friction) while maintaining a good couple. Doppler recommends éffectuer a 300km break-in and use the oil DOPPLER Racing 2t or the Ipone STROKE 2R was up 2.5% with super unleaded 98.

In short this kit will do you gain performance without neglecting the strength. It will be great for the road and competition. We enjoyed the very channels worked on this vortex model ....

We advise to accompany this kit with at least: reinforced crankshaft, bearings, unlock coil, racing exhaust, racing dampers and 21mm minimum carburetion 17,5mm to operate well, candle B9 or B10, alignment cylinder transfers / casings recommended!

The pack contains:

Ø39.84mm piston mono-segment axis 12mm

Cylinder aluminum strip 5 transfers

two hard chrome domed segment Ø39.84X1mm

Polished hemispherical cylinder head Ø39.84mm

Cylinder head screws

Optional we offer a preparation course 1, this preparation is a modification of the channels and the exhaust port by increasing the charts and improvement of the duct, it increases the cylinder performance. Improved piston and bottom skirt is also included in the amendment. Allow a little extra time for this preparation!
