I had an 04 300 and just got an 05 280. The 280 is so much nicer to ride in my opinion, smoother and im not as affraid to give it big licks on the throttle whereas the top end on the 300 is helish.
Yeh the 300 is smooth but i think the 280 this year is smoother. i had a go on them both, Birkett also thought that the 280 is the bike this year, it carburates loads better than the 300 aswell which has got the old ducati ignition on!! had problems with that! Plus its silver. get a 280, in red its about as sexy as a trial bike can possibly be. I got gold rims on mine, looks proper bling
