I wonder if you could compare part numbers from Kymco? I don't know what the difference in the two may be. With a low cost model I can't see them making a lot of proprietary parts but don't know for sure. Can you compare part numbers on your old speedometer to the 4t speedometer? I beleive the 4t is 37200 per parts outlaw wasn't sure if the other model is correct for your 2t.
