我住在泰国曼谷。 我有雅马哈 R3 和川崎 Z400。 我更换了雅马哈 R3 的前后链轮,以赋予它更多的动力。 对于川崎Z400来说,情况恰恰相反。 它的功率太大了,我会将前链轮更改为 15,并保持后链轮相同。 如果你把前后链轮换成泰国规格,你可能会发现 400 太强大了,有时有点危险。 I live in Bangkok Thailand. I have both the Yamaha R3 and Kawasaki Z400. I have changed the sprocket front and back of the Yamaha R3 to give it a little bit more power. for the Kawasaki Z400, it is the opposite. it has too much power and I will change the front sprocket to 15 and keep the rear sprockets the same. if you change the front and rear sprockets to Thailand's spec you might find the 400 too powerful and a bit dangerous at sometimes.
