Hello Guys, back again on Silaban Channel. This time we will again discuss the Vega R bore motorbike using the Honda Vario 125 piston. Using the Vario 125 piston is PNP, just install it without making any changes. Unlike the Kaze piston, where when we use this piston in a Vega R engine we have to change it. Both in the piston tail and piston head. Using the Vario 125 piston in this Vega R engine has several advantages, the compression is denser because the piston surface is a little thicker, but it doesn't over-compress. The piston is lighter because its length is shorter than the original Vega R piston. The movement of the piston in the liner is also smoother and lighter with minimal surface friction. #silabanchannel
