I am going to go along to everyone else and say that is a really big step up. Honestly there is a pretty good argument to be made that for sport bikes at least liter bikes do not really have any business on being on the road. 9 times out of 10 a 600 will serve you better. I for one can get onto more than enough trouble on a smaller bike.

One really good way to think about it. All bikes have more or less the same amount of travel in the throttle(60° if I remember correctly). So a bike making 30 hp will give you 1 hp for every 2°. One making 60 hp will give you 1 hp for every 1° and one making 120 HP will at 2 hp per degree. You have to be way more precise on the high HP bikes. It isn’t just making sure you only use half the throttle.
