hehhe janay de yar .. I did it once with friend who had gto 110 , when I had CG and I only gulped lots and lots of blue smoke of GTO ... never even came close to it... in 1st and 2nd gear I was ahead and then it was GTO all the way..
Some time back in this very same thread I saw a comparison chart and 4 stroke bike must be double or atleast 3/4 in 'CC' to beat a half of its cc in 2Stroke.
If you have experienced a 250cc 4stroke/16 valve/ 4 cylinder Sports bike you must have seen its top speed hardly 160 ~ Max180(ideal - never actually happens) where as RX 115 can hit 150+ in speed and its less then even half of 250cc. So you can well imagine.
