UMA Racing Super Head Pro for Yamaha 135LC – Increase at least 28HP

Racing Boy has unveiled today in its FB page this UMA Racing Super Head Pro for Yamaha 135LC. One of the interesting claim of this parts is that it will “increase at least 28HP’. The stock horsepower for Yamaha 135LC is 12HP, so this Super Head Pro are giving additional 16HP to the bike! That is a very brave claim from Racing Boy. I kept looking for the valve size but couldn’t find it. I also don’t know whether this is a special valve head or not. Maybe it is pneumatic valve system?

  1. illogical. 250cc bikes are 26HP at most, and this can pass that. Don’t even need to change anything? Just plug in head and you get 28HP?

    These guys are geniuses!

  2. Teramat tak logik..kebanyakan orang buat macam-macam, blok, head, cam, bearing, ekzos, cdi, baru dapat MAXIMUM pernah tengok 25hp, kalau setakat tukar head ni dapat 28hp, masuk barang2 lain, perghh… kompem 35hp, tambah dengan motor ringan, stakat ER6 rasa kompem boleh kejar.

  3. Skali depa reply camni kat komen :
    “Racing Boy – fix with UMA cylinder 62mm, carburator 34mm, and exhaust, then you will get 28hp ♥”
