dea i m using dyl yd 70 and have put 20,000 km's on it,its feul efficiency is pretty much close to 45-50 rang ,, the 2010 + models may do 55+.as the first batchg of dooms were doomed ,, first batch had some serious problems,, but heared new modeel ratified them.. regarding body i wwould say its very very strong and wxcellant quality no rust so far,, mud stick to it no corrosion at any place,, si i would suggest u buy the dyl 70..
another option is ravi premium r1,, that has 88cc engine bakol some ravi man here,, annd doom is 78cc honda is 72cc... dyl is pretty cheap at i think 47k,,or 46k,, and it has best resalle value as well according to market here in pindi islamabad,,
reagrding 100cc's i dont know too much cuz never used them for long ,, but suzuki 110cc and junoon are excelant ,, junoon was very impressive and mmy friend says it is giving him a realistic 50 km/ltr ,, if u can pay a bit more i wpoiuld say don buy anything below 100cc,,, they are realy pathetic and uncomfortable nbikes,, no good road grip and pick,, and then on double sawari the 70cc is something very pathetic and on 100cc u will anjoy double sawari..
