Just my opinion , suzuki did a great job on redesighning the busa .yeah i know the tail thing , but power braking handling comfort are all greatly improved , i have ridden the 05 33000 miles all have been great , i have almost 300 miles on the 08 and can already tell major differences , the greatest improvement is the fuel delivery system , the throttle is seamless with no rough spots , un like my 05 when i was riding it home from the dealer asking myself what have i done , it needed the power comander and a map to smooth things out , second is the acceleration , it is truly mind blowing , and third the shifting , shifting the o8 has more of an electronic feel to it , i know its still linkage but this is an area suzuki has improved alot , riding the 05 home between the clunky shifter and rough throttle i was a bit dissapointed with the purchase .
