NK Racing CT125 428轉420改裝套件 (RK製金色油封鏈條 & FR齒盤)

428 轉 420 改裝套件
對於 125cc 的引擎排氣量來說，428 尺寸的鏈條是超出規格的。
與 CT125 採用相同引擎，但輸出功率更高的 Super Cub C125、GROM、Wave125 等車款都採用 420 尺寸的鏈條。

將 428 鏈條降級為 420 鏈條的優點是透過輕量化，使加速和減速更加順暢。加速變快，煞車效果也更好。阻力減少，油耗也會改善。當然，最高速度也會提高，透過採用油封鏈條，保養週期得以延長，與非油封的 428 鏈條相比，油封型的 420 鏈條調整間隔更長。

同時提供前後齒盤套件

he 428 size is over spec for 125cc engine capacity.
The Super Cub C125, GROM, Wave125, etc., which have the same engine as the CT125 but even higher output, are 420 size.

The effect of downsizing from a 428 to a 420 chain is smoother acceleration and deceleration due to weight reduction. Acceleration is better and braking is more effective. Fuel consumption is also improved due to reduced drag. Of course, the maximum speed is also increased, and the maintenance cycle is lengthened by using a sealed chain.

Sprockets, front and rear, are set to match.

CUT is necessary because the number of chain links is 120.
(CT125 has 108 chain links)
