Douth

Hello everyone, Im new to biking and to the site, iv been coming on here every night for the last 2 weeks whilst iv been waiting to pick up my new bike. Picked it up on wednesday its a FZ6 S2, already done 400 miles, i love it. Its restricted at the moment but i was just wondering if there is a big noticable difference when you get them de-restricted? either on the top speed, acceleration or both? Cheers
