Attention kit in bi segment!
Here is a small very powerful cylinder, the DOPPLER S1R has an aluminum cylinder with racing architecture, revised and corrected exhaust, high diagrams ...
The piston is a domed hard chrome two-segment model to limit friction and allow higher speeds. The cylinder head is a polished frustoconical high compression chamber.
A very good little kit to gain in performance while respecting the 50cc displacement!
The pack contains :
X2 piston clips
X2 segment
X1 racing cylinder head
X1 piston Ø40mm
X1 piston pin 10mm
X1 aluminum cylinder 5 transfers exhaust boosters Ø40mm
X1 high engine gasket set
...
As an option we offer a stage 1 preparation, this preparation is a modification of the channels and the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement to the piston and the bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
