IM running about 29.5 in the back that goes up to about 33 ish when track hot. I like it there, I dont see any problems with my rear end.
It was recommended to try a bit lower, like 27 but it grows a bit much like 5 to 6 psi, and I think is a bit squirrely in hard corners.
So, basically right there 29 to 30 is the sweet spot cold. I get a nice even wear on the tire, it looks really good actually and they last a decent amount of time too.
Im running 31 to 32 in the front, it'll hit 36 ish in the front when hot. You have to remember, when it comes time to shed speed, especially if you have to do so quickly, that battery is a LOT of weight transfer forward in a hurry, you want that front loaded up to hold it. Not to mention if you are running a hard regen mode, you can probably easily transfer half your body weight or more to the handlebars as well, which will be picked up by the front.
Thank you for sharing this!
Looking at the numbers I am guessing these are for your EGO in racetrack setting. Surely, on the street with your Ribelle you choose a higher pressure?
I had a (street) one-on-one training last week and the instructor encouraged me to reduce the tire pressure from the 2.9 bar / 42 PSI (Energica spec).
Currently I am trying 2.7/39 rear and 2.5/36 front. Still running on the Pirelli Diablo Rosso III.
Especially the reduction in front tire pressure improved the handling of the bike so much!
The reduction on the rear tire feels a bit wobbly sometimes, especially when accelerating after the apex of the curve. IDK if this is a bad thing.
