Yamaha lc135 : more speed, and much more comfortable when compared with the Honda wave 125. i rode a wave 125 for like 4 years and the comfort which comes with the mono-shock on the Yamaha is unbeatable.. besides.. the Yamaha looks way cooler than the Honda. :)
honda wave and honda xrm is same engine,.. it depends on the driver but xrm and wave is beaten by my kawasaki aura,..
It should be stamped on one of the sides, Or simply count it.
