dear can i add something ....
i have SD-110 Flash..
in short little diference between Flash and Sprinter..
SD-110 Flash ka head cylender originally 108cm ka hai..
jabky Sprinter 110ka head cylender originally 109cm ka ha..
baqi engine ke material SD-110 ka behtar hai..ziyada strong hai...
but a negative point is still here with SD-110, which is its both rear and front alloy rims..these Alloy Rims are very heawy , but they have plus point also that they cant turned to dented in case of accident..but in severe condition they just turn to pieces..like hard matel..
and on front of Flash, there is company fitted HOOD, which is very helpful to safe the front light and also add beauty in outlook of bike..
in short : agar bike bhagani hai ya race lagani hai tu go for Sprinter aor agar beauty aor reliablity chahye for long time then chose Flash...
