Been rinding sports bikes for the past 9 years and i´ve done everything you can do on a road bike...I feel it´s time for a change, something new to challenge me. Anyway to the point. 400 vs 650. i´m 6ft 3, 110kg and will be riding around the Top End were i live in Darwin. People say "your big enough for a 650", others say "650 is a pig, get a 400 cause it is more nimble, lighter etc. I´ve riden them both, but because my off road experience is nill i wasn´t able to see what they were made of. I´m 85% sure to get the 650. i can´t see how 14kg weight difference can make a bike a pig. I need your opinion.
