me a dhoom user its engine is just a piece of crap .. better buy some well established brand of cHonda .. narrow ur choice to ravi or super power or uniquue ud100 .. there is slight diifference in petrol consumption of petrol b/w 70 and 100 ... but 100cc offer grt pick/power /...
how much would u be running it daily ? kitnay km ?
if ur daily avg use is little like (20-30km) better buy 100cc ( would recomend unique ud100 or superpower )or alspo consider 125cc chonda ..
for 70 dont go for thoom its poor thing overly expensive ..
