Komplekte rasite:

• 77cc alumininį cilindrą. 50mm su 5 įsiurbimo angomis.
• Vienžiedį Vertex stūmoklį. 50mm
• Monoblokinė cilindro galva, aliumininę.
• Pilną tarpinių komplektą

Cilindro komplektas pribloškia savo paprastumu (nereikalinga jokia bloko modifikacija), galia ir patikimumu.

- Installation is very easy, crankcase milling or any other modification are not necessary. Squish clearance is pre-set to a value optimized for the respective engine type. 
- In terms of output, the BigRacing cylinders knock it out of the ballpark: we measured a whopping 23 PS and 13 Nm on our P4 test bench using a standard set-up (24mm carburetor, original ignition, racing exhaust etc.). 
- Port timings are relatively low, cooling system volume is quite large and the piston is a top quality Vertex piston. All of these factors contribute to the cylinder's high dependability and robustness, provided that set-up and adjustments are appropriate. 

Naudojant šį 77cc cilindro komplektą mes patariame naudoti ir stiprintą (sportinį) alkūninį veleną.

Išorėje rasite 49cc užrašą, tačiau nesijaudinkite - įsigyjote tikra 77cc cilindrą!
