Maybe you should try to understand my answer before you write anything.
1 I am not completely dissatisfied with the handling. The handling is good. But from my point of view not perfect and you can improve it. That's exactly what I do. 90% satisfied and 10% dissatisfied.
2 As I have written, my problem will not occur with bigger and heavier people. You wrote in another thread that you are 6.3 tall (192 cm) and about 215 to 218 pounds (about 100 kg) heavy. I am significantly smaller and lighter than you. Please understand that people are different and therefore everyone else may have problems.
3. do you already have the Comfort seat of the Supersport? Then you have already done a part of my planned modification. Then you sit higher than me and have a much bigger lever than me with your heavier body. Then it is no wonder that you are completely satisfied with the handling.
And one more thing: With the Ducati Supersport I intentionally bought a sporttourer. That means I want to ride it like a sporty touring bike. If I have to ride the Supersport like a real Superbike, then the Ducati Supersport is the most useless bike in the world. From my point of view, Ducati must develop the next supersport more towards Touring in order to increase the distance to the Panigale family. With my modifications I am already doing this with the current Supersport.
yes I have tried to understand. My comment is simply that I disagree. Not with what you want to achieve but rather with the belief that the change in bars will result in better handling of the Supersport. I do think you may be more at ease with the wider bars as it is what you are used and therefore you may end up happier having them but my point is technically I don’t believe it would better the handling. I also don’t see that a heavier rider has any greater advantage over a lighter rider by distributing there weight to help the bike turn better if anything it can be worse by unbalancing the natural line of the bike and introducing the need for more bar input to correct the balance. Good luck with it mate. It’s your bike and I am sure you will get what your after in the end.Maybe you should try to understand my answer before you write anything
