buying-2-discount-300pxl-.png● 160CC CYLINDER KIT, HIGH COMPRESSION (eSP+ 125CC/150/160 ENGINES) (12100-K0S-V60)

● The one thing the old Forza125 4-valve, and the new 125, 150 and 160 eSP+ 4V engines have in common, is that they are all sharing the same intake and exhaust valve sizes, and even exactly the same cylinder heads if it comes to the 125, 150 and 160 eSP+ engines!

● It's surprising to see that Honda have chosen to install the same crankshaft on both the 160 and the 125 engines, with also the head of the 160 engines on the 125cc engines.

The result of this is that you get an engine a very low compression ratio (11.5:1 to be exactly for the 125, and this is 12:1 with the stock Honda 60mm piston installed).

● The reason why the compression ratio is still low if you are installing a stock Honda 60mm 160 piston is because Honda has chosen to use a dish type piston instead of a flat piston.

● By installing the YUMINASHI 60mm cylinder kit (12100-K0S-V60) with the flat piston on a 125 you're not only getting a 156.86cc engine, but you also get the compression ratio where the head was basically designed for, and if you have a 150 or 160 engine, then the higher compression piston in the set has the possibility to produce more power compared to the stock 160 piston so both the 125 and the 150/160 engines have a benefit with installing this kit.  

 

● PISTON DETAILS:

● The piston you get in the 160cc YUMINASHI high compression kit is not only a higher then the stock 160 piston, but also a lighter piston compared to stock, where the valve pockets are prepared to run a high lift performance camshaft.

● The hard chromium plating layered (Cr) piston rings which come with the set are produced by very strict Japanese standards and has excellent characteristics which combine the original properties of chromium metal with the advantages of erector-deposits!

The main benefits from the chrominum plating layered piston rings are extremely high hardness of HmV (Micro Vickers), 800 to 1100 (cf. gray cast iron 220 to 270), high melting point of approx. 1800°C (cf. cast iron 1200°C), good thermal conductivity and corrosion resistance, a low friction factor and excellent wear resistance, such features are very effective in preventing piston ring wear.

● The enlightened piston is made from A-grade materials and the piston skirts come with a molybdenum coating. The Anti-detonation grooves on the top ringland provide several advantages, which include further atomization of the combustion charge to prevent damage to the piston and ring caused by pre-ignition. These grooves also prevent carbon build up on the ring land which can cause the compression ring to stick in the ring groove.

The pressure seal groove will prevent gas build up below the top compression ring; these gases can cause the ring to lift from the ring groove. Unseating of the ring will result in compression losses and lower performance.

The valves of the 160cc and 125cc head are the same size, there is no difference in valve size between the 125 and 160 4V head.

We recommend to install the 170cc B-type 8-holes injector (LINK) in combination with this 160cc cylinder kit.
