 Product Description

buying-2-discount-300pxl-.png● 140CC (53MM /12MM PISTON PIN) HIGH COMPRESSION PISTON (2021 GROM125 - 2021 Z125 MONKEY - 2021 W110i/125i...)

● This 13102-K26-G53B 140cc Light Bore Piston is the second piston set we have released for the stock 110cc and 125 cylinder head, and this is the high compression version set which comes complete with the 53mm Japanese grade piston rings (LINK), 12mm piston pin & 12mm piston clips.

● A lot of time and effort went into the design and the road testing of this piston, and this in combination with different injectors, camshafts, roller rockers and even fuel blends to be ensured that the compression isn't "over the top" which could result in broken piston ring lands, or in a hole in the piston in case of too deep machined valve pockets in combination with heat and pressure...

● We saw that installing a high degree camshaft result in a compression loss of about +/- 20psi pressure, and with our high compression piston installed you are still at +/- 170 to 180psi pressure which is perfectly save to be used, and results in making good power without "overdoing" things...

● We recommend to install a 14T front sprocket (LINK) in combination with this piston because the 5th gear ratio is way way way too heavy, and you will never be able to make a good top speed if you shift to 5th gear with the stock 15T front sprocket installed (if you are a person with a +100Kg (220 Ponds (lb) personal weight, then we recommend to install a 13T sprocket (LINK))

※ This high compression piston for the stock cylinder head can perfectly be used with E85 ethanol fuel, and this results in a cooler and even more powerful engine (Don't use an injector smaller than 170cc/min)...
※ If you don't want a high compression piston to raise the compression ratio, then we have you covered because we have the low compression 140cc Light Bore Piston also available with this (LINK), which allows you to make a choice concerning the bore size and the compression you would like to see on your engine tune....

※ If you install a very high lift camshaft, then it could be that the valve pockets in the piston need to be modified based on the lift of your camshaft (This will be fine with 95% of the camshafts available, but it's always worth to check this to avoid damage).
※ This 140cc high compression Light Bore Piston needs to be installed with minimum a 170cc/min B-type injector (LINK) (flow rate of the injector to be used will be based on your location in the world)...
※ The 5-speed 2020 GROM125 and 5-speed 2021 Z125 Monkey models are called "the 2022 model" in the USA...
※ 140cc is only achieved on the 125 models in combination with the stock 125 crankshaft and not with the C110 or Wave110i 110cc crankshaft.
