Kit 150cc RRD Ø57,4mm, cylinder / piston for motorcycle HONDA CBF, SDH, ARCHIVE SCRAMBLER AM64 ... 125cc from 2008 to 2016

!!! STARTING PRICE !!! Ideal in combination with a sport exhaust like the TURBOKIT, ARROW or other and a gearbox output pinion with one or two more teeth as well as a good colder racing spark plug CPR8EAIX9 (ETE) or CPR7EAIX9 ( WINTER), here is the 150cc RRD kit!

 

 

It is mounted on injection engines as well as on carburettors! A 28 to 30mm carburetor can also accompany the beast but the origin is also suitable (we recommend increasing the main jet all the same to properly adjust the air / fuel ratio, during your adjustments, you can use the AFR POLINI to point the correct AFR of 13 so have good performance without worrying about running too lean).

 

 

Its 57.4mm diameter takes you from 124.99cc to 150cc real torque and power (in combination with the original 57.8mm stroke crankshaft).

The original cylinder head and crankshaft can be preserved without problems! This kit is delivered complete with piston, seals, segments, axis, clips ...

 

 

Very correct or even high quality, this kit remains an element manufactured in Asian countries, piston machined in the cap, cast iron jacketed cylinder, quality steel segmentation, honor in the rules of the art ...

 

The cylinder is made of aluminum for good cooling with an internal cast iron jacket. Very high quality OPM Asian manufacturer!

 

 

This makes it an extremely solid cylinder! The finish is excellent! The cylinder is covered with a specific metallic gray protective paint for temperature conduction!

 

Mounts on HONDA ... 4T 125cc air cooled engine mounted on many other 125cc motorcycles, Ø13mm piston pin. The compression ratio is also greatly increased for more torque and power, only use SP98, ban SP95.
