I'm sitting on the fence at the moment don't know weather to get a OS .25 or wait to see what the V-Spec replacement is....... I have also thought about the Ninja .21 as it has the better bottom end that the V-Spec.... I know a few that are racing the OS .25 today at the local will see what they have to say about the .25 as most of them have had the OS range V-Spec .21, Speed .21 and the mighty OS .28...... But i defiantly don't want to leave the OS camp......
