According to me, rx 135, 100 and bullet are the real bikes. Others are just Japan made toys. The style, the comfort rx 135 provides is beyond explanation. Now it's becoming a trend that purchasing for low price and modifying it. It provides 5x speed than rx 100. 2 stroke engine is used, so fuel consumption is high. That sound while a rx 135 runs on road make everyone to look. I ll definitely suggest this product.
