since i have used it in both alter and stock states i think i have a good view of both copnditions..
first and foremost is that if you are into races stunts and dangrous riding style .. then nothing is safe ..
my observation is thta when it was stock it was dangrous and i had a few mishaps with it..
after altering it it had much pick and power and it was a bit safe.. because i could quickly accelerate and get out of trouble..
rest my riding style remained same ...
my bike after alteration would touch 100 but i have used it mostly upto 60-70.. and very rarely used it above this range .. and only to feel the thrill i would give it full race (again if one rides at this high speed then its dangrous no mater its stock or altered.. i mean riding any bike in its peak power is dangrous .. there is little power left to get u out of dangerous situation. say if i used normal bike at 70km/hr then there was little power left behind and after alteration i had a lot of power left .. this has helped me in many instances..)
these are my observations.. others may differ..
