Yesterday i visit McLeod road lahore. I inspect unique UD70 and UD100cc in different showrooms there. Believe me or not the worst quality of 70cc bike i have ever seen was by Unique. You can't believe what was my feeling when i saw both bikes. I asked price of both, dealer told me Rs.55,000 for UD100 and Rs.43,500 for UD70.
I probably suggest you take a look on Unique alternatives Yamaha Dhoom 70, Pakhero and Metro 70cc bikes. I know these are also not excellent in quality but in my opinion these brands quality seems better then Unique company. Rest its up to you. Make your choice.
