 Product Description

buying-2-discount-300pxl-.png● YUMINASHI 125CC (53MM) LIGHT BORE UP PISTON V2.0 (NAVI110 / ACTIVA110 3G) (OVERSIZE 3.00) (13101-KWP-D53)

● YUMINASHI has worked this 53mm (122.60cc a.k.a. 125cc) Light Bore Piston Set out as a powerful low cost solution to bore up the stock NAVI10, or ACTIVA110 barrel (cylinder block) up, from the STD 50mm to 53mm bore, which is a 3.00mm oversize.

● The term "Light Bore" is a reference to the fact that this piston has been designed to be installed with the stock 110cc cylinder head, and the stock 110cc 25.5 IN / 21mm EX valves.

● The squish area on the V2.0 piston has a flat face and a rough finish to improve air fuel atomization and create a more efficient fuel curve with less ignition timing.

● By installing the Light Bore Piston you hit 2 birds with 1 stone, because you are raising the low compression from the stock engine, and you are sucking more air in with the 3mm larger 125cc piston, so by sucking harder and getting more air in you can install a larger main jet, or even the larger YUMINASHI/KEIHIN PE24 carburetor & Manifold to get again more power out of your engine.

● The piston has been developed in combination with the YUMINASHI high lift SS240 Super Sport Camshaft and YUMINASHI Racing Digital CDI Unit to create a powerful combination and to make the real performance difference for the NAVI were you are looking for. 

● Plug & Play solution!...

※ If you are using the stock NAVI or ACTIVA carburetor, then installing a larger main jet is required!...
※ Need to be installed with the 53mm Copper Head Gasket Set (LINK), a 54mm gasket can also be used (LINK).
※ The stock barrel (cylinder) need to be bored up, and we recommend a piston to cylinder wall clearance of 0.05mm (0.002inch).

info-icon-25pxl-.png The wall thickness will be 1.45mm after boring the stock NAVI110 barrel/cylinder block up, which is perfectly fine, and still reliable to do so.

  • 1 x 53MM PISTON
  • 1 x 53MM PISTON RING SET
  • 1 x WRIST PIN 12x33.8MM
