I have a tomos targa and i also feel that my speedometer isint reading accurately. I was thinking about getting a derbi's dash installed into my Targa's but I dont fare enough. I think that my Targa may read in km/h (its a 2001 targa fyi). But i KNOW that it can go faster than 33 kmh with a 110 lb. guy on it. So it must be MPH. Ahh, who knows really what the new targas read?
